Description

Antenna component

Technical field

The present invention relates to be used for as on the electronic equipment of mobile communication equipment, personal computer and analog to finish the antenna component of wireless telecommunications.

Background technology

In portable terminal, as cellular phone, the quantity of equipment is rising constantly, and each terminal is equipped with the antenna component that is used to finish with other electronic equipment wireless telecommunications except the common whip antenna or built-in aerial that are used for the telephonic communication purpose.

The quantity of Portable mobile electronic device such as notebook computer is also increasing, and this equipment can be finished with those of quantity growth and be equipped with the wireless data communication of the electronic equipment of antenna component.

In addition, owing to be basic demand to portable terminal and notebook computer reducing size and power conservation feature in recent years, and the miniaturization of strong request antenna component.Because recent Communications service variation, produced a plurality of standards, because antenna component need be suitable for use in the communication according to a plurality of standards, expect also that therefore antenna component can finish the transmitting and receiving of frequency of different-waveband.

An example as the said chip antenna, have a kind of antenna component to comprise to be arranged on the insulated substrate of prism (prismal) shape spiral helicine conductor and in the terminal at substrate two ends, one of them terminal is used for power power and inserts and connect (the open 2001-326522 of reference example such as Japan Patent).Figure 44 is a perspective view of describing the prior art antenna component.Substrate 103 is made of as for example pottery the insulating material of prism shape, and power is supplied to the terminal 101,102 that is arranged on 103 liang of opposite ends of substrate one of them.Helical conductor 104 perhaps removes the conductive layer formation that is plated on the substrate 103 by repairing by coiling copper cash or analog.Because can do very for a short time, this antenna component can easily be installed in portable terminal and the analog.

The antenna that also has another kind of type, this single antenna can transmit and receive the signal (the open 2002-33616 of reference example such as Japan Patent) of a plurality of frequencies individually.Owing to can transmit and receive the radio wave of a plurality of frequencies,, use this antenna to make it unnecessaryly have a plurality of antennas for portable terminal with individual antenna.

Yet, can only transmit and receive the radio wave of an independent frequency at the disclosed antenna component of 2001-326522, though theirs is small-sized.

On the other hand, though disclosed antenna component can transmit and receive the radio wave of a plurality of frequencies in open 2002-33616, have bigger framework and be not suitable for reducing size because complex structure requires many assemblies and electricity supply element.When considering the operation of actual installation especially, obviously reduce size and be suitable difficulty.Particularly, antenna component need be suitable for reducing size, low section and energy-conservation to portable terminal, notebook computer and analog.

In addition, owing to be basic reducing size and power conservation feature these years to cellular phone and notebook computer, thereby want to make the antenna assembly miniaturization.Simultaneously along with the raising of emissivities, wish that also antenna can work on the frequency band of broad.In addition, to as the multi-process (multi-career) of OFDM (OFDM) but method is necessary in the further growth of bandwidth of operation.Form electric capacity by increasing conductor to the top ends of antenna component, may produce can be at the little and lightweight antenna component (reference example such as Japan Patent disclose H10-242731) than broadband work.

Figure 45 is the perspective view that is provided with the prior art antenna component of conductor, and this conductor forms electric capacity at the point of antenna.Capacitor board 105 is as the load capacitance of helical conductor 104, and the frequency response of the input impedance of antenna component is flattened, and makes frequency bandwidth broaden.As disclosing as shown in 2002-124812 and the H10-247806 at Japan Patent, the use of crown conductor is a general knowledge.

Yet in the structure of the antenna component shown in the H10-242731, the conductor that forms electric capacity need be attached to the point of antenna.This causes a problem promptly, and especially when mounted, owing to the element that need increase quantity makes complex structure also bigger, it is too big that antenna becomes.This has also increased the quantity of manufacturing process, and it is difficult to the low cost manufacturing.Because especially for portable terminal and notebook computer, little and energy-conservation is indispensable, therefore wish the antenna component miniaturization.Yet the crown conductor that is attached to the point of any one rod shape antenna or pattern antenna is a problem, because the entire antenna device becomes too big.Especially to cellular phone and laptop and since they need do the littler thinner limit until them, thereby do not wish very much to use big so dimensionally antenna assembly.

Also has a problem, promptly when antenna assembly such as rod shape antenna and pattern antenna, it is loaded with a crown antenna at point, when being installed to main circuit board, perhaps select the degree of flexibility of crown antenna pattern to descend, if perhaps give the shape more flexibility of crown antenna, the area of the device that need be used to fix up an aerial wire increases.In addition, need to solve another problem, as because the gain loss that antenna causes with respect to the position of main circuit board.

Antenna assembly is built in laptop, portable terminal and the analog.Some examples are disclosed in Japan Patent open 2003-163521, H10-200438, H11-4117 or the like.When antenna assembly will be installed in the electronic equipment, the position of installation was determined according to the specification of this instrument.If make portable terminal or analog, the installation site is the top of instrument normally.

Yet another problem is need be on the circuit board big erection space of antenna assembly, and this requires circuit board to have extra length to this degree.When circuit board is done more, the housing of portable terminal also needs extra length to hold it, is difficult to reduce the size of portable terminal thus.

Summary of the invention

The invention provides a kind of antenna component, it comprises the helical conductor that is arranged on the substrate, be arranged on a pair of terminal on the substrate, wherein a helical conductor in these a plurality of helical conductors is electrically connected to a terminal, and has a helical conductor to be electrically connected to another terminal in addition.

Embodiment

Below, the description to one exemplary embodiment of the present invention is provided with reference to the accompanying drawings.

First one exemplary embodiment

Fig. 1 is the perspective view that illustrates according to the antenna component of first one exemplary embodiment.

Substrate 1 is formed by insulating material or dielectric material as aluminium oxide or pottery by using compression moulding, extrusion modling and similar approach, and main component is an aluminium oxide.Other are suitable for comprising ceramic material as the material of the component of substrate 1, as forsterite, magnesium metatitanic acid base, calcium metatitanic acid base, tin zirconium titanium oxide acidic group, barium metatitanic acid base and plumbous calcium metatitanic acid sill, and resin material such as epoxy resin.Consider the easiness of intensity, insulating property (properties) and processing, in first one exemplary embodiment, use aluminium oxide or have with the pottery of aluminium oxide as main component.Substrate 1 also is provided with conducting film in its whole outer surface, and this conducting film comprises one or more layers that be made up of electric conducting material such as copper, silver, gold, nickel and similar material.

All chamferings of all limits of substrate 1.Provide chamfering can prevent that substrate 1 from breaking, prevent that conducting film lacks thickness and prevents conductors against damage.

End 2,3 is formed on the two ends of substrate 1.Substrate 1 can have the cross section with end 2,3 same sizes, or its (stepped down) that can be rank fall makes mid portion have the area of section littler than end 2,3.Provide rank to fall part and allow substrate 1 when being installed to circuit board, to keep its periphery and circuit board surface that an interval is arranged, and prevent its character variation.Rank fall part and can only be formed on the part of substrate 1 outer surface, or whole surface.When in whole when surface that part is formed in substrate 1, fall in rank, when installation base plate 1, do not pay particular attention to be which side of substrate 1 to circuit board, reduced the cost of installing thus.

The end 2,3 of substrate 1 is provided with terminal 5 and 6 respectively, and this terminal comprises connecing after hope is applied by plating at least, vapour deposition, sputter, silver slurry fires the conductive film that (firing) one of them and similar approach forms.Terminal 5 or 6 is as the power access point, and is connected to current feed department.Terminal 5 or 6 another be connected to an open solder joint or an analog that separates with other circuit, with the intensity of guarantee installing and finish electromagnetic emission.In first one exemplary embodiment, though substrate 1 all is provided with terminal 5 and 6 at its two ends, it only needs a terminal is that one of terminal 5 or 6 are as the power access point.As mentioned above, terminal is connected to current feed department power and inserts and allow another terminal for open, allows substrate 1 to transmit and receive signal as antenna.

In addition, though terminal 5 and 6 is arranged on whole side surface, reach the end face that also is arranged on end 2 and 3 in the mode that covers fully, they can be arranged on the only side in four sides.Optionally, terminal can be arranged on all four sides of end 2 and 3.

Helical conductor 7,8 and 9 is formed on the surface of substrate 1, rather than the surface of end 2 and 3.Spiral-shaped slits in helical conductor 7,8 and 9 is formed on the whole periphery of substrate 1.One end of helical conductor 7 is electrically connected to terminal 5, and an end of helical conductor 9 is electrically connected to terminal 6.Helical conductor 8 be placed in make between helical conductor 7 and 9 its not with 7 and 9 any one be electrically connected.That is, single helical conductor 7,8 and 9 does not have the electricity continuity each other.In other words, a spiral-shaped slits 4 that is positioned between helical conductor 7 and 8 is severed conducting film on substrate 1 surface for continuous morphology, as shown in Figure 1, has cut off the electricity continuity between helical conductor 7 and 8 thus.Another spiral-shaped slits 4 between helical conductor 8 and 9 also is a continuous form and sever conducting film in a similar manner.Thereby helical conductor 8 and 9 is that electricity is separated.

In this structure, though do not connected by electricity, helical conductor 7 and 8 is capacity coupled mutually. Helical conductor 8 and 9 also is capacity coupled.

Description to the operation of antenna component with a helical conductor at first is provided.

Fig. 2 is the diagram that the equivalent electric circuit of the antenna component with a helical conductor is shown.More given condition of resonances, resonance frequency can be expressed by following equation 1:

${\mathrm{\ω}}_0=1/\sqrt{L\·C}$ (equation 1)

As can be known, when having inductance composition and capacitive component, antenna has the electromagnetic function of the characteristic frequency of transmitting and receiving from equation 1.The electromagnetic frequency that the value decision of inductance composition and capacitive component can be launched and receive.In other words, the capacitive component of the inductance composition of helical conductor and substrate decision resonance frequency omega ₀This principle will be explained the operation of the multiple resonance of antenna component.

Fig. 3 A is the diagram that the equivalent electric circuit that only has an antenna component that is formed on the helical conductor 7 on the substrate 1 is shown, Fig. 3 B is the diagram that the equivalent electric circuit with two another antenna components that are formed on the helical conductor 7,8 on the substrate 1 is shown, and Fig. 3 C is the diagram that the equivalent electric circuit with three another antenna components that are formed on the helical conductor 7,8,9 on the substrate 1 is shown.The example that terminal 5 wherein is used as the power access point is shown.Antenna component shown in equivalent electric circuit statement Fig. 1 of Fig. 3 C.Shown in Fig. 3 C, capacitor C 1 is formed between helical conductor 7 and 8, and capacitor C 2 is formed between helical conductor 8 and 9.In addition, helical conductor 7 has inductance component L 1, and helical conductor 8 has inductance component L 2, and helical conductor 9 has inductance component L 3.

Here, when supposing C1 and C2, transmit and receive frequency and provide by the resonance frequency that L1 and C1 determine all at isolated state.On the other hand, if only C2 is assumed at isolated state, transmit and receive frequency by L1, L2 be connected in another resonance frequency that C1 therebetween determines and provide.In addition, if C1 and C2 are assumed to not at isolated state, transmit and receive frequency and provide by another resonance frequency that L1, L2, L3 and connected C1 and C2 determine.In brief, because antenna component shown in Figure 1 comprises three helical conductors in a single chip component, thereby it can realize three different resonance.

The antenna component of these triple resonance can transmit and receive the signal of the frequency of wanting, as near 800MHz (for example being used for the telephonic communication frequency), near 1.5GHz (frequency that for example is used for GPS) with near 2.4GHz (frequency that for example is used for the high speed wireless data communication).

The realization that transmits and receives on the wave band of 800MHz is by using antenna component as Comparatively speaking long antenna, wherein shown in Fig. 3 C, independent helical conductor 7,8 and 9 and capacitor C 1 and C2 be capacitive coupling.The realization that transmits and receives on the wave band of 1.5GHz is by such use antenna, promptly helical conductor 7 and 8 and capacitor C 1 be capacitive coupling, simultaneously capacitor C 2 is counted as in theory at isolated state.The realization that transmits and receives on the wave band of 2.4GHz is that promptly antenna has helical conductor 7 by such use antenna, and capacitor C 1 and C2 are counted as in theory at isolated state simultaneously.

Except the above, other combination also is considered to reach the frequency as transmitting and receiving triple resonance antenna components, comprising:

(1) as near 800MHz (for example being used for the telephonic communication frequency), near 1.5GHz (frequency that for example is used for GPS) with near 1.8GHz (for example being used for telephonic communication frequency) at the wave band different with 800MHz; And 2.4GHz (frequency that for example is used for the high speed wireless data communication).

(2) as near 800MHz (for example being used for the telephonic communication frequency), near 1.8GHz (for example being used for telephonic communication frequency) at the wave band different with 800MHz; With near 2.4GHz (frequency that for example is used for the high speed wireless data communication).And

(3) as near 900MHz (for example being used for frequency), near 1.8GHz (for example being used for telephonic communication frequency) by the DCS-1800 system by the GPS communication; With near 1.9GHz (for example being used for telephonic communication frequency) by the GSM-1900 system.

In Fig. 1, though embodiment comprises three helical conductors and obtains the antenna component of triple resonance, the antenna that has two helical conductors under the situation of dual resonance is suitable, and if want four and more resonance, then four and more helical conductors are suitable.Yet if the series connection of many helical conductors, it is oversize that antenna becomes dimensionally.Thereby for dual to provide two to five helical conductors to five heavy resonance be suitable, but the present invention is not limited to top example.

Fig. 4,5,6 and 7 is the perspective views according to the antenna component of first one exemplary embodiment, and they illustrate the different structure of the antenna component that is used for Fig. 1.

Antenna component shown in Figure 4 has the plane surface structure, and wherein substrate 1 is not provided with rank and falls part.The structure that this has quite simplified substrate 1 makes and has improved productivity ratio on the certain degree.

Though be made of the prismatic substrate with square-section at the antenna component shown in Fig. 1 and Fig. 4, can replace them is that polygonal is prismatic as triangular prism, five jiaos of prisms or the like.

As shown in Figure 5, substrate 1 and end 2 and 3 also can be made of the cylinder with circular cross-section., this shape may bother in installation process, and for example compared with the structure in Fig. 1 and Fig. 4, its can roll on circuit board.Yet,,, can very accurately form spirality conductor by rotating it forming in the process of helical conductor 7,8 and 9 by laser and grinding grinding because the outer peripheral portion that lowers from rank, substrate 1 two ends has circular cross-section.

Optionally, substrate 1 and end 2 and 3 can form the plane surface structure and not have rank to fall part, as shown in FIG. 6.

In addition, substrate 1 can be built as the combining structure between those in Fig. 1 and Fig. 5, and as shown in Figure 7, its medial end portions 2 and 3 is square-sections, and the middle body that 2 and 3 rank lower from the end forms circular cross-section.Because the polygonal cross-section of end 2 and 3, antenna rolled when this structure prevented to install.Because it has circular cross-section in the part of helical conductor formation place, this structure allows to form point-device helical conductor by laser and grinding helical conductor while rotational substrate 1 in addition.Antenna component has spiral-shaped slits 4.

Provide below and have the helical conductor description of the antenna component of conduction connecting structure each other.

Fig. 8, Fig. 9 A and Fig. 9 B illustrate the perspective view according to the antenna component of the different structure of first one exemplary embodiment.Antenna component 20 have for the part 15,16 of non-helical shape and 17 arbitrarily.Unlike the antenna component shown in Fig. 1, those antenna components are provided with the helical conductor 7,8 and 9 of mutual electrical connection. Non-helical part 15,16 and 17 is the zones that do not form spiral, and they are not provided with spiral-shaped slits 7b, 8b and 9b.Use with Fig. 1 in the element of identical Reference numeral designate similar.The material that is used for substrate 1 identical with reference to the description of figure 1 is as pottery and resin material.

Substrate 1 and end 2 and 3 have rectangular shape, and promptly to have than size longer on the vertical direction in the horizontal be suitable.Such reason is when substrate 1 has the length of specific degrees, guarantees the intensity of element body.The helical conductor that same reason may be used among Fig. 1 is non-conductive situation.

Fig. 9 B illustrates the perspective view of the antenna component of making rectangular shape, and it has the advantage that element body has intensity, especially when the mounting core chip antenna, and the advantage that durability is improved in the back is installed.

Fig. 8 illustrates the example with the antenna component that wherein is formed with three helical conductors, and Fig. 9 A and Fig. 9 B illustrate the example with two helical conductors.

Figure 10 A, Figure 10 B and Figure 10 C are the diagrams that is illustrated in the equivalent electric circuit of the antenna component shown in Fig. 8, Fig. 9 A and Fig. 9 B.Helical conductor 7,8 and 9 has the inductance element that is denoted as L1, L2 and L3 respectively, and non-helical shape part 15,16 and 17 has capacitive component, and they are together in series.Figure 10 C illustrates the example with three each parts of helical conductor and non-helical shape partly being made of of picture in antenna component shown in Figure 8 20 situations, and Figure 10 B illustrates as the example with two each parts that partly are made of helical conductor and non-helical shape at the antenna component shown in Fig. 9 A and the 9B.Antenna component shown in Figure 8 has triple modes of resonance, comprises by the resonance frequency of L1 and C1 decision, by another resonance frequency of L1, L2, C1 and C2 decision, and by another resonance frequency of L1, L2, L3, C1, C2 and C3 decision.On the other hand, the antenna component that shows at Fig. 9 A and Fig. 9 B has dual mode of resonance, comprises by the resonance frequency of L1 and L2 decision and by another resonance frequency of L1, L2, C1 and C2 decision.

This can provide the antenna component as an individual component, and it is still to for example 900MHz (for example being used for the frequency by the GPS communication), 1.8GHz (for example being used for the communication frequency by the DCS-1800 system); And 1.9GHz (for example being used for the frequency by the PCS communication) is adaptive.Certainly, antenna component only can be designed as to two in these resonance frequencys or four or mostly be adaptive.This point by provide four its each partly constitute by helical conductor and non-helical shape and realize.

The peak frequency that this antenna can transmit and receive is by inductance component L 1 and capacity cell C1 decision, the inductance composition with around the number of turns (being the number of turns of spiral) proportional, and the square root of frequency and inductance composition is inversely proportional to.Therefore transmitting and receiving frequency can improve by reducing the number of turns.Therefore, the electromagnetic frequency that transmit and receive can improve considerably by the number of turns that minimizing is connected at the helical conductor 7 of the terminal 5 of power supply receiver side.

Figure 11 is the perspective view that illustrates according to other structural core chip antennas of first one exemplary embodiment to Figure 17.These antenna components have and those the different structures shown in Fig. 8, Fig. 9 A and Fig. 9 B.

Figure 11 illustrates and forms the plane surface structure, does not have the antenna component that part falls in rank.Structure falls in the rank that have on the whole periphery at substrate 1 at the antenna component 20 shown in Fig. 8, Fig. 9 A and Fig. 9 B, makes end 2 and 3 stretch out to improve installability.Yet on the other hand, the plane surface structure can obviously be simplified the structure and sizable the boosting productivity of substrate 1.

Figure 12 illustrates has the antenna component 20 that forms cylindrical substrate 1 and end 2 and 3.Cylindrical when being shaped as, antenna component 20 has out of order possibility in installation process, and for example it can roll on circuit board compared with prism structure.Yet because antenna component 20 has circular cross section, it have raising with laser beam and analog on substrate 1 repair the efficient of removing operation and the advantage of accuracy, make and improve the accuracy that is formed on the spiral-shaped slits in the helical conductor.

Antenna component 20 shown in Figure 13 is provided with cylinder-shaped end 2 and 3 at the two ends of cylindrical base 1, and wherein substrate 1 is that the periphery of end 2 and 3 that makes that rank fall stretches out from substrate 1.Be provided with prismatic end 2 and 3 at another antenna component 20 shown in Figure 14 at the two ends of cylindrical base 1.It is that the polygonal cross-section of end 2 and 3 prevents that antenna from rolling when mounted that these structures can provide advantage, and when forming by laser beam or grinding, realizes point-device helical conductor in the circular cross-section of substrate 1 middle body.

Having such structure at the antenna component 20 shown in Figure 15,16 and 17 is that the part of non-helical part has big external measurement.

Each of these antenna all is provided with the protuberance 18 with big external measurement at the part place of non-helical part 15.Protuberance 18 has the external shape with end 2 and 3 same sizes.Because non-helical part 15 and 16 has capacitive component, their electric capacity can increase by the external area that enlarges them as protuberance 18.Big capacitive component can increase the load capacitance of antenna component, and bandwidth is broadened.When it was installed to circuit board, except end 2 and 3, by with scolding tin or analog protuberance 18 being connected to conductive region, so these structures also had the advantage that improves installation strength.

Figure 16 and 17 illustrates the example of difform protuberance 18.

Protuberance 18 shown in Figure 16 has the external shape that extends laterally, and makes electric capacity increase and bandwidth is broadened.Because this structure provides protuberance 18 big basal surface, has increased soldered area when it is installed to circuit board, and has further improved installation strength.Terminal 2 and 3 can be formed the size same with protuberance 18, and perhaps they can be of different sizes.When end 2 and 3 bottom surface are arranged to protuberance 18 mutually concordant, can easier antenna be installed on the circuit board.

In the example of Figure 17, protuberance 18 and end 3 all are that U-shaped is to increase surface area and their capacitive component.This increases their electric capacity more, and frequency bandwidth is broadened.This length that also can reduce antenna component 20 keeps the amount of enough capacitive component simultaneously.

As the alternative scheme of U-shaped, protuberance 18 and end 3 can form comb teeth shape with their surface area of further increase and capacitive component.

With reference now to Figure 18,19 and 20,, provide down a kind ofly, antenna component is provided with the description of the situation of diaphragm.This structure adapts at non-electric-connecting each other any antenna component of the wherein helical conductor shown in Fig. 1 or the like, and reaching at the wherein helical conductor shown in Fig. 8 is those antenna components that are electrically connected mutually or the like.

Figure 18,19 and 20 is coated with the front view and the cutaway view of the antenna component of a diaphragm according to each of first one exemplary embodiment.Antenna component comprises in diaphragm 21, tubular diaphragm 22, electro-deposition diaphragm 24 and the conducting film 23 any.

Figure 18 illustrates diaphragm 21 and is arranged on structure on helical conductor 7,8 and 9.Diaphragm 21 has improved the weather resistivity, and prevents owing to other electronic component physics on helical conductor and the circuit board contact the character variation that causes.Diaphragm 21 need be set to cover helical conductor 7,8 and 9 at least.It is suitable as epoxy resin that diaphragm 21 is used any resin material.Perhaps, silicon rubber and analog also are suitable for use in this purpose.What wish in addition is that the material that is used for diaphragm 21 has low dielectric constant as far as possible.This is because when being wrapped, the material of diaphragm 21 is easy to flow into the slit, thereby if has high dielectric constant, the resonance point of possible portable antenna.Therefore wish to have low dielectric constant.

Yet,, considered the dielectric constant or the similar characteristics of diaphragm 21, the antenna performance that can obtain to want when the yardstick of the structure of helical conductor 7,8 and 9 and the not coupling part between it is designed in advance.

It also is suitable that the rank that diaphragm 21 is formed on substrate 1 fall in the part, this make it the surface with end 2 and 3 surperficial equal or lower level on.The diaphragm 21 of Xing Chenging can not cause any surface of when antenna component is mounted terminal 5 and 6 and the loose contact between the circuit board by this way.

Diaphragm 21 can form by resin material or the analog that applies or wrap up paste-like.

Figure 19 illustrates the diaphragm that forms by the diaphragm 22 that uses the image tube shape.

The diaphragm 22 that uses the image tube shape can be protected helical conductor effectively and not change their characteristic.That is, the diaphragm 22 of image tube shape is arranged on the substrate 1 in the mode that covers each helical conductor 7,8 and 9, and making does not have other materials can flow in the slit and space between the helical conductor in forming the process of diaphragm.Therefore the diaphragm 22 of image tube shape unlikely changes characteristic.To the diaphragm 22 of image tube shape, those that select to be made by the castable resin with pyrocondensation characteristic are suitable.The diaphragm 22 of image tube shape is placed as and encircles a heating process covering substrate 1 and attended the meeting this pipe of contraction.This is the fixing diaphragm 22 of image tube shape in the place on substrate 1 securely.

Figure 20 A, Figure 20 B and Figure 20 C illustrate the another kind of form as diaphragm, and electro-deposition diaphragm 24 is arranged on the example on the conducting film 23 that is formed by the helical conductor helical form.Unlike the diaphragm of being made by resin material as the diaphragm 22 of diaphragm 21 and image tube shape, it is suitable that this electro-deposition diaphragm 24 is used metal materials.

Electro-deposition diaphragm 24 is with different in the situation shown in Figure 18 and Figure 19, and it only protects the spiral helicine conducting film of staying on the helical conductor that forms.In other words, it does not cover spiral-shaped slits 4, and only covers the conducting film 23 that is formed on the spiral section.Electro-deposition diaphragm 24 is made of metal material more excellent on the weather resistivity; more specifically; its by at least from as gold, platinum, palladium, silver, tungsten, titanium and one group of material of nickel a kind of metal of selecting or exclude a kind of alloy that the element in the above-mentioned material group forms from above-mentioned group of a kind of material of selecting and another and make.Consider cost and weather resistivity characteristic, especially preferably use gold or billon.Electro-deposition diaphragm 24 forms by the method as plating, sputter and vapour deposition.

Be considered to adoptable in the structure shown in Figure 20 B and Figure 20 C as the shape of electro-deposition diaphragm 24.In other words, almost completely with the whole surface of electro-deposition diaphragm 24 covering conducting films 23, protect conducting film 23 in the structure shown in Figure 20 B thus reliably.Only with the outer surface of electro-deposition diaphragm 24 covering conducting films 23, stayed the side that forms spiral helicine conducting film 23 in the another kind of structure shown in Figure 20 C.Though this structure is compared with to a certain degree the low-level weather resistivity of providing among Figure 20 B, because the surface that exposes is quite little corresponding to the thickness of conducting film 23, it remains practical concerning its purpose.

Can be by on the surface of a part or whole base plate 1, forming earlier conducting film 23, secondly repairing and remove spiral-shaped slits 4, form diaphragm 24 by electro-deposition or similar approach thereafter and be structured in the structure shown in Figure 20 B.

Can be by on the surface of a part or whole base plate 1, forming earlier conducting film 23, form diaphragm 24 at conducting film 23 tops, repairing thereafter and remove spiral-shaped slits 4 and be structured in the structure shown in Figure 20 C.This process only produces electro-deposition diaphragm 24 at the outer surface of conducting film 23.

Electro-deposition diaphragm 24 thickness are suitable at (more preferably, between 0.1 micron and 5 microns) between 0.05 micron and 7 microns.If thickness is less than 0.05 micron, it does not just provide enough weather resistivities.If thickness is greater than 7 microns, the possibility of the short circuit between adjacent helical form conducting film 23 will increase, and causes the problem that cost increases, although it has not really significantly improvement on weather resistivity characteristic.

For guaranteeing not deterioration of stable properties, it is suitable that electro-deposition diaphragm 24 keeps low resistance as antenna.Consider this point, it is suitable using one of gold, billon, platinum, platinum alloy, palladium and palldium alloy (being platinum group metal and platinum metal alloy).

In addition, some metals as tungsten, titanium and nickel form oxide on its surface, and the formation of oxide layer provides stable weather resistivity.Though these metals may depend on the concrete condition in the use in the little variation of using the back to produce gradually for a long time in antenna characteristics, they also are useful to antenna for suitable occasion.For solving top problem,, prevent characteristic deterioration after use thus being pre-formed oxide layer on the surface of electro-deposition diaphragm 24 in manufacturing, to adjust its characteristic.

It may be that antenna is avoided as in the damage of installing and taking place between the operating period and the problem of characteristic changing that the diaphragm that forms in top mode makes it.

Next the formation of helical conductor 7,8 and 9 described.

Figure 21 describes the diagram that forms the method for helical conductor according to first one exemplary embodiment.Method herein illustrates the substrate 33 of swinging mounting 30, motor 31, laser irradiator 32, conducting film covering and repaiies the slit 34 of removing out.

In this example, the preparation of the substrate 33 that conducting film covers is the whole surfaces that are formed into substrate 1 by one or more layers conducting film that will be made of the electric conducting material as copper, silver, gold and nickel, and is used for laser processing procedure as device shown in Figure 21.In Figure 21, the substrate 33 that conducting film covers is set in swinging mounting and by revolution, and spirality repair the slit 34 of removing out then by the substrate 33 that covers from laser irradiator 32 radiation lasers to conducting film simultaneously mobile in one direction laser irradiator 32 and swinging mounting 30 at least one of them and cut out.Conducting film 34 is divested completely from the slit in this process, stays the spirality conducting film when repairing after slit after removing forms.Here the spirality conducting film that stays is as spirality conductor 7,8 and 9.

When make shown in the image pattern 1 that the same have the antenna component of discontinuous type helical conductor the time, the not coupling part between helical conductor 7 and 8 be by interrupt laser irradiator 32 relatively the moving of substrate 33 of conducting film covering relative to break-in repair the annulus of removing and form around substrate 33.Perhaps, the formation in this slit can be two region overlappings (being that adjacent slit forms in overlapping mode) that make laser emission by the such degree that relatively moves that slows down between the substrate 33 of laser irradiator 32 and conducting film covering.

The antenna component with a plurality of electrical connection helical conductors of that another kind of type can be by supspending the substrate 33 that laser emission and mobile conducting film cover after forming first spirality conductor with laser emission as shown in FIG. 8, restarts laser emission again and form next spirality conductor with the position after moving and form.This method is made non-helical part between the conductor of adjacency.

Among the exemplary in the above embodiment, though show the laser emission that conduct forms the method for single helical conductor, other are repaiied, and processing also is useful as emery wheel except that means.

In said method, because conducting film is formed on the whole base plate 1, conducting film also covers the surface of end 2 and 3.Therefore the part that conducting film covers end 2 and 3 can be used as terminal 5 and 6.Optionally, the conducting film on end 2 and 3 can be also at least one covers to form terminal 5 and 6 by the anticorrosive film of being done by for example nickel (weld decay prevents film) with by tin or by tin mixes in the adhesive film that the lead-free solder of the alloy composition of other metals (not comprising lead) does.Perhaps independent helical conductor can be made from the conducting film on the middle body 4 that only is formed on substrate 1, and another group conducting film forms by conductive paste such as the silver slurry that applies and fire on end 23.By the two ends of connection conducting film and corresponding each side of conductor, these conductors of firing can be used as terminal 5 and 6.The conductor of firing also can further be covered by any above-described anticorrosive film and adhesive film.

As another example, helical conductor 7,8 and 9 can make up by the fine rule of coiling electric conducting material.When this situation, by use adhesive or by resin molded method fixedly fine rule to substrate 1.Perhaps, substrate 1 can be provided with a plurality of isolated conducting films, and an end that forms the helical conductor 7 of fine rule is connected to terminal 5, the other end is connected to first of these isolated conducting films, one end of helical conductor 8 is linked second conducting film with first isolation, the other end is to the 3rd conducting film of all isolating with any above-mentioned conducting film, and an end of helical conductor 9 is linked the 4th conducting film of all isolating with any above-mentioned conducting film, and the other end is to terminal 6.Via by thermo-compression bonding, ultrasonic bonding and the similar approach of not using binding material the conductor wire end of helical conductor being bonded to conducting film, this structure has and is easy to independent helical conductor is fixed to advantage on the substrate 1.

The thickness of single helical conductor, length etc. can obtain from the suitable result of experiment according to the characteristic of operative installations.In single helical conductor, be used for that the interval scale of coupling part can be from suitable experiment and similar acquisition yet.

Suppose that helical conductor is 5 to 20 microns on thickness, and substrate 1 yardstick is 7 millimeters of diameters, 23 millimeters of length, for example, helical conductor 7,8 and 9 needs electrode length 15-20,20-30 and 50-60 millimeter respectively around substrate 1.In the minimum interval that needs between helical conductor 7 and 8 and another minimum interval between helical conductor 8 and 9 is respectively 0.1-0.2 millimeter and 0.1-0.2 millimeter.Yet the length of electrode depends on the capacitance variation of C1 and C2 coupling, and they need be adjusted to obtain optimal properties.

Use Figure 22 and Figure 23, provide to as above the description of the experimental result finished on the antenna component that makes up of discussion.

Figure 22 is the chart that the VSWR (being voltage standing wave(VSW)) according to the antenna component of first one exemplary embodiment is shown, and Figure 23 illustrates a pair of diagram according to the directivity of the antenna component of first one exemplary embodiment.All these results obtain from experimentation.

These experimental results are to carry out on the antenna component of the helical conductor on the substrate 1 having two, and adjust to 900MHz and 1800MHz wave band.Use network analyser measuring voltage standing-wave ratio or VSWR at this band, and directivity.

Can obviously find out from Figure 22, approximate correctly reach impedance matching, its illustrate to GSM cellular phone (880MHz is to 960MHz) and DCS cellular phone (1710MHz is to 1880MHz) both on wave band voltage standing wave ratio all less than 3.In other words, these results show that it can be finished and transmit and receive because this antenna component produces enough gains in transmitting and receiving on these wave bands.Also very clear, antenna component has been finished dual resonance on 900MHz and 1800MHz wave band, and so single this antenna component can transmit and receive the electromagnetic wave with two different frequencies.

Figure 23 illustrates the directivity of antenna component on Y and Z direction.From Figure 23, can obviously find out all have omnidirectional's directivity at 900MHz and two wave bands of 1800MHz.

From aforementioned, can obviously draw, yet the present invention has realized can transmitting and receiving with very little discrete component the antenna component of a plurality of communication frequencies.In addition, because substrate is provided with a plurality of such structures of helical conductor that have spiral-shaped slits, compared with traditional rod shape antenna, paster antenna and analog, it is very little that it can be done.This antenna component thereby can easily be built in little, thin and the highly integrated electronic equipment such as portable terminal, notebook personal computer and analog that any needs do.

When using λ/4 type Antenna Design, the present invention has also realized antenna component is made very little element, and very little antenna is provided thus, and an one monolithic can transmit and receive a plurality of frequencies.

Antenna component in this one exemplary embodiment adapts to the high frequency band of any actual frequency scope at 0.7-6.0GHz, and the appropriate size of length L, height H and width W is

L=4.0 to 40.0 millimeter

H=0.5 to 10.0 millimeter, and

W=0.5 to 10.0 millimeter.

Any length L 4.0 or littler antenna can't reach the inductance value that needs.The antenna that surpasses 40 millimeters on the length L is considered to too big and hinders carrying circuit board of electronic component or reducing of analog (following finger circuit board) size, limited thus the electronic equipment that is used for built-in this circuit board size reduce the space.If height H and width W all are 0.5 millimeter or littler, antenna element is in the time can becoming too weak so that attaching it on the circuit board etc. with erecting device on the physical strength, and it may damage.If any one of height H and width W is 10 millimeters or bigger in addition, antenna element can be excessive so that it stops circuit board and electronic equipment to be reduced in size.

Second one exemplary embodiment

Figure 24,25,26A and 26B are the perspective views according to the different antenna components of second one exemplary embodiment.

In this one exemplary embodiment, provide to be installed in the description of antenna component that the antenna open end is used for the crown conductor of the wave band that broadening transmits and receives to having.

Being arranged on helical conductor in the antenna component herein can be the just type with electricity noncontinuity of Fig. 1 discussion of picture, or picture just Fig. 8 discussion have a successional type of electricity.

Antenna component 40 comprises crown conductor 41, distributing point 42 and current feed department 43.Omitted below to have with Fig. 1 in the description of assembly of identical Reference numeral.Figure 24 provides the example with two helical conductors.This antenna component 40 is the structure that helical conductor 7 and 8 mutual conductions are connected.

Antenna component 40 can be at the multiple mode of resonance with a plurality of helical conductors shown in Figure 24 and Figure 25, or at the single mode of resonance that only has a helical conductor shown in Figure 26 A.

Distributing point 42 is formed by pad, wiring diagram or analog, and is connected with terminal 5 by welding or similar means.Distributing point 42 is accepted from the signal code of radiating circuit supply and by terminal 5 it to be guided to the antenna component 40 of radiated electromagnetic wave.Perhaps, antenna component 40 sends the electric current that gone out by the electromagnetic wave induction that receives to receiving circuit.

Crown conductor 41 is an independent domains that is not connected with other circuit or ground wire as the open end.Crown conductor 41 is formed by wiring diagram, pad or analog, and is connected with terminal by welding or similar means.Because crown conductor 41 has electric capacity, it has as the equal effect that connects a load capacitance terminal 6.Though Figure 24 illustrates tetragonal crown conductor 41, it also can be other polygonal shape, as triangle and pentagon.Figure 25 illustrates an example, and it is the crown conductor 41 of triangle, and Figure 26 A illustrates another example, and it is the crown conductor 41 of pentagon.In addition, Figure 26 B illustrates the example of another antenna component that provides the crown conductor 41b on the installation surface of the protuberance 18 that forms around non-helical part.In this structure, crown conductor 41b is used as the load capacitance that is used for the relevant resonance frequency of broadening pair and helical conductor 7 and crown conductor 41, and crown conductor 41 is used as another load capacitance to the resonance frequency relevant with helical conductor 7 and 8, and each that is implemented in thus in the multiple resonance frequency all realizes broadband operation.

Crown conductor 41 can be that other shapes are as oval and circular.Because crown conductor 41 with capacitive component be loaded into beginning terminal 6, so crown conductor 41 has been expanded frequency bandwidth.Because the value of capacitive component is an important factor in this structure, wish that flexibility ground forms the optimum shape of the crown conductor 41 relevant with the assembly of other installations to guarantee capacitive component.Shape such as triangle, quadrangle and pentagon, and size can according to circumstances be defined as suiting.Be arranged near in the situation of antenna component 40 at other assemblies, crown conductor 41 can form the shape or the flat pattern of elongation, so that it can be installed in the appropriate location for other assemblies, to be issued to significantly reducing of whole erection area in feasible situation.

In this structure, the frequency of operation wave band that is used to transmit and receive depends on the value of load capacitance.Crown conductor 41 has capacitive component, and this capacitive component is as the load capacitance for distributing point 42 that is attached to the tip of antenna.Therefore, from distributing point 42, crown conductor 41 is a load impedance.Herein, the rising delay time of the gain curve of resonance frequency and fall delay time are directly proportional with load impedance.In other words, the rising delay time of the gain curve of resonance frequency and fall delay time can change according to the value of the load capacitance of the value of load impedance or crown conductor 41.For example, if load capacitance is little,, represent the frequency response characteristic of gain curve to have sharp-pointed peak because rising delay time in resonance frequency and fall delay time are short.On the other hand, if load capacitance is big,, represent the frequency response characteristic of gain curve that the peak of inclination gradually is shown because rising delay time in resonance frequency and fall delay time become long.Yet, having such possibility promptly, gain descends when bandwidth is broadened.Therefore it is crucial finding balance by selecting as the suitable size of the crown conductor 41 of load capacitance and capacitive component that dielectric constant is adjusted load capacitance between optimum gain and the bandwidth wanted.

Figure 27 is the diagram displaying that illustrates according to the frequency response curve of second one exemplary embodiment.Two frequency response curves are arranged, a situation of representing little load capacitance, the situation of the load capacitance that another representative is big.The curve display of little load capacitance goes out the sharp-pointed peak that increases with the gain at the resonance frequency place, and the curve display of heavy load electric capacity goes out the peak of the mitigation that increases with gain.The inclination at peak relaxes more, and is just wide more at the frequency of operation wave band that transmits and receives frequency, by the capacitance that is provided by crown conductor 41 is provided frequency band broadened like this.

Owing to the trend of the expansion of the recent volume of transmitted data in wireless telecommunications, need to obtain enough wide frequency of operation wave band, because this needs, to come the broadening bandwidth be very important by using crown conductor 41 to improve load capacitances.The multi-process as requiring broadband OFDM (frequency division multiplexing) that above-mentioned technology is particularly suitable for is in recent years transmitted.

Ensuing providing to showing the description of crown conductor 41 these true experimental results of broadening frequency band.Figure 28 is that the diagram that is illustrated in the result of experiment of finishing in second one exemplary embodiment is showed.Fig. 1-1 illustrates the vertical scale of given crown conductor 41 and the relation of bandwidth, and VSWR is equal to or less than the predetermined value of the correct condition of resonance of representative under this bandwidth.This curve display goes out when the vertical scale by increasing the crown conductor of quadrangle simultaneously during the constant surface area that increases crown conductor 41 of breadth wise dimension, the change on bandwidth.The predetermined value of VSWR is 3.

In this Fig. 1-1, transverse axis sign vertical scale and the longitudinal axis is represented bandwidth.The area of crown conductor 41 increases with the increase of vertical scale.The increase of area means the increase of the value of capacitive component C1.Can see obviously that from Fig. 1-1 bandwidth enlarges with the increase of vertical scale.Can confirm be when vertical scale by when increasing to 10 millimeters with respect to 4 millimeters, bandwidth has enlarged 40%.This makes that the transfer rate of data may increase by 40% when modulator approach, error correction rate and data speed keep identical.

Fig. 1-2 illustrate the representative crown conductor 41 area crown conductor 41 vertical scale and transmit and receive in gain between relation.From Fig. 1-2, can obviously see, may not cause any problems such as adverse effect that reach performance as gain decline by the area of regulating crown conductor 41 and enlarge bandwidth, or even when frequency band is enlarged.

The growth of vertical scale and the increase of bandwidth normally are in direct ratio.In the computing formula of Q value as can be known, the square root of bandwidth and electric capacity

Proportional, the area of electric capacity " C " and crown conductor 41 is proportional, and if foursquare words, the quadratic power of the length of side of the area of crown conductor 41 and crown conductor 41 is proportional.Therefore, top conclusion is that the length of side of bandwidth and vertical scale or crown conductor 41 is proportional.Also clearly, this theory result that can be obtained from Fig. 1-1 confirms.

In this connected, load capacitance can be linked the electric capacity that the terminal 6 of open end has by use and be formed by the electric capacity that the part of the circuit board that is connected with terminal 6 provides with another.Yet the width that this needs the length of some extra measures such as dorsalis medullae spinalis extension base 1 and increases terminal 6 is to guarantee enough capacitances.These measures cause the shortcoming as the increase of antenna component size and extra manufacturing process.Opposite, the present invention makes it possible to easily obtain enough load capacitances by connecting terminal 6 to pad and at the crown conductor 41 of its most advanced and sophisticated formation.In addition, the present invention also provides such advantage, and promptly when the position relation of consideration with other installation components, even after the manufacturing of finishing antenna component, can easily form crown conductor 41 and increase load capacitance and can form it neatly is Any shape.

Figure 29 is the diagram that illustrates according to the structure of the antenna assembly of second one exemplary embodiment.Antenna component is installed on the circuit board, and is provided with the crown conductor that is connected with the antenna component open end.

Antenna component comprises the lateral edges 51 of main circuit board 47, auxiliary circuit board 45, Power feed 46, RF circuit 48, processor circuit 49, control circuit 50 and main circuit board 47.Main circuit board 47 and auxiliary circuit board 45 are with respect to mutual same level, and they are electrically connected by Power feed 46.Not not being grounded plate and covering on main circuit board 47 by RF circuit 48, processor circuit 49 and control circuit 50 region occupied.Control circuit 50 is to be used for processor controls circuit 49 and analog, and it uses CPU, IC customized or the like.Processor circuit 49 is finished and is added identifying code (error code) and demodulation as modulation and in signal transmission and function such as error correction in received signal.The signal of modulation is changed into signal on tranmitting frequency by the RF circuit in processor circuit 49, and outputs to antenna component 40 by Power feed 46.On the other hand, the signal of antenna component 40 receptions outputs to RF circuit 48 by Power feed 46, change frequency in RF circuit 48, and demodulation in processor circuit 49.At the antenna component 40 shown in Figure 29 and Figure 30 are the dual mode of resonance antennas with helical conductor of two electrical connections.Yet it can be the antenna component of other types, comprises not the helical conductor that connects, and is suitable for use in triple and the antenna that shakes of multi resonant more.

When antenna assembly is built in cellular phone or the laptop, such situation is often arranged, promptly consider the available erection space and the easiness of installation process, be more suitable for antenna assembly being installed to independent auxiliary circuit board 45 rather than being installed on the main circuit board 47 with multiple treatment circuit.In other words, to auxiliary circuit board 45 and it is linked main circuit board 47, can simplify installation process by mounting core chip antenna 40 in advance with Power feed 46.If antenna component 40 is installed on the main circuit board 47, and is opposite,, and the risk owing to the performance degradation that is caused by the phase mutual interference of generations such as noise is arranged because main circuit board 47 also has RF circuit 48 except processor 49.Mounting core chip antenna 40 demonstrates bigger advantage to independent accessory plate 45 for this reason.This also provides another advantage promptly, and accessory plate 45 can provide antenna component 40 with greater flexibility in the space that guarantees to be used to have the crown conductor 41 of essential shape of extension frequency wave band and surface area.

When antenna component 40 is λ/4 types, the surface of its ground plate on main circuit board 47 produces image current (image current).In this example when antenna component 40 is installed in usually direction perpendicular to the lateral edges 51 of main circuit board 47, the image current that produces in the ground plate of main circuit board 47 has and the essentially identical vector of electric current that flows in antenna component, makes and improves the gain that antenna component 40 transmits and receives.Thereby, mounting core chip antenna 40 on usually perpendicular to the direction of main circuit board 47 preferably.Especially when antenna component 40 was λ/4 types, its produced the induced current that is equivalent to λ/2, comprises image current, thus antenna component to produce image current effectively be very important.Thereby it is inevitable that the accessory plate 45 that has the main circuit board 47 that is used to allow the ground plate that the image current that produces flows and be loaded with antenna component 40 is placed on same plane usually.

The existence of crown conductor 41 has increased load capacitance and has therefore widened frequency band, the feasible naturally antenna component optimization that is used for the wireless telecommunications of high transmission rates.

As described, the present invention can guarantee to transmit and receive enough levels of gain, and improve the performance of antenna component 40, simultaneously by mounting core chip antenna 40 with accessory plate that main circuit board separates on and two circuit boards are placed on suppress noise on the general same horizontal plane and keep design flexibility crown conductor 41.In addition, when the accessory plate 45 that has the main circuit board of processor circuit 49 and analog and have an antenna component 40 when installation is built in cellular phone or the laptop, because they are placed on generally is on the same horizontal plane, this structure can reduce the space that is used to install these two circuit boards.The performance of antenna assembly is even as transmit and receive under the superincumbent situation of level of gain and also can remain on the high level effectively.

Figure 30 is the diagram that illustrates according to the structure of another antenna assembly of second one exemplary embodiment.Figure 30 illustrates antenna component 40 and crosses main circuit board 47 and be placed on the example that the accessory plate 45 on the same substantially horizontal plane is installed with main circuit board 47.

Distributing point 42 is arranged on the main circuit board 47, and the terminal 5 of antenna component 40 is connected to distributing point 42.On the other hand, crown conductor 41 is arranged on the accessory plate 45, and the terminal 6 of antenna component 40 is connected on the crown conductor 41.That is, main circuit board 47 and accessory plate 45 interconnect by antenna component 40.Even the present invention adopts this structure, having the shape of the crown conductor 41 of raising and the advantage of the flexibility that surface area designs reaches, because main circuit board 47 and accessory plate 45 are placed on same plane, realize that electronic equipment reduces the advantage of size and low section thereby reduce the space that is used to install main circuit board 47 and accessory plate 45.Accessory plate 45 shape and size form that to make the shape and size of itself and crown conductor 41 match be suitable.Perhaps, accessory plate 45 can make with the same shape and size of crown conductor 41 so that the minimized in size of accessory plate 45.

Because the direction of antenna component 40 is basically perpendicular to the lateral edges 51 of main circuit board 47, the image current in the ground plate of main circuit board 47 that is produced by antenna component 40 has the essentially identical vector with the electric current that flows in antenna component 40, make to have and improve the advantage that transmits and receives gain.When antenna component 40 is λ/4 types, its generation is even more important with the image current of antenna component 40 identical vectors, transmits and receives gain because it need improve by generation image current (this image current produces the induced current that is equivalent to λ/2 types then).For this reason, antenna component 40 need be installed on the direction vertical with the lateral edges 51 of main circuit board 47.Install under infeasible situation vertical, antenna component 40 can be according to other situations of mounting condition and electronic equipment, consider with performance on the balance of shortcoming, and be installed as with vertical direction at angle.Even in the superincumbent situation, the ground plate of main circuit board 47 can be used as the ground plate that produces image current, and to obtain the improving advantage that transmits and receives gain, this advantage is very important, especially to the antenna component 40 of λ/4 types.

Above the structure ground plate that make to use the main circuit board 47 that processor circuit 49 and analog are installed become possibility as the ground plate of antenna component 40, and antenna component 40 can be used as λ/4 type antennas.Thereby can make antenna component 40 and therefore antenna assembly miniaturization like this.Above structure decrease the space of the device that is used to when being built into electronic equipment in the time to fix up an aerial wire, the low section of realizing electronic equipment thus with reduce size.Therefore it can improve by image current and transmits and receives gain and improve the performance of extension frequency wave band by the function of crown conductor 41, still keeps described small size simultaneously.The expansion of frequency band realizes the wireless telecommunications of high transmission rates.

The other multichannel ability that transmits and receives frequency is used two or more antenna components 40 also is suitable in order to have concerning electronic equipment.

If it is not parallel with the lateral edges 51 of main circuit board 47 to be formed on the edge of ground plate of main circuit board 47, antenna component 40 need be installed in the edge with ground plate, rather than on the vertical substantially direction of lateral edges 51.In this way, antenna component 40 can be used to produce image current well.

When using a plurality of antenna components to be applicable to diversity, the present invention also is useful to the receptivity of improving electronic equipment.For example, when two antenna assemblies were installed, it is suitable for finishing selected diversity promptly to improve receptivity by the high-power signal that demodulation is optionally received in antenna assembly, and combination and variation and obtain the high specific of combination based on the power of receiving.

As described above, this antenna assembly can be realized broadband operation by crown conductor is provided, substantially be on the conplane accessory plate and use the ground plate that is arranged on the mainboard can improve high-gain by crown conductor being installed in, by crown conductor being installed in the flexibility that can guarantee on the accessory plate to the design of crown conductor shape and area size with main circuit board.

The 3rd one exemplary embodiment

In this 3rd one exemplary embodiment, provide a kind of when antenna component is installed to portable terminal and analog, reduce the installing space description of the method for the performance of holding core chip antenna simultaneously.

In common practice, when being installed to portable terminal and analog, antenna component often attaches it to the top of circuit board.This need be on circuit board big area.Thereby this makes circuit board length become inevitably greatly, and portable terminal is wanted containment circuit board like this, makes terminal be difficult to realize that size reduces thus.

Using owing to the reason that reduces size in the situation of λ/4 cake core antennas, especially, is to guarantee the gain that requires, necessity when ground plate of sufficient size is arranged.This makes the space with length necessitate to be used to fix up an aerial wire, because it also depends on ground plate.Corresponding to top described, be that circuit board and two further growths on length of electronic equipment are unescapable with regard to causing such problem.

Opposite, owing to the three-dimensional ground of antenna component and effectively utilized available space and reduced installation length, the use of the antenna component in this one exemplary embodiment can be implemented in wants to reduce the portable terminal of size and the optimum mounting structure in the analog.

Figure 31,32,33 and 34 is the schematic diagrames that illustrate according to the structure of the antenna assembly of the 3rd one exemplary embodiment.

This antenna assembly comprises antenna component 55, circuit board 56, circuit mounting area 57, antenna mounting panel 58, ground plate 59, bent angle portion 60 and foreshortened length 61.

Can be clear that in Figure 31 the primary flat of antenna mounting panel 58 tilts with respect to the primary flat (promptly distributing to the face of circuit mounting area 57) of circuit board 56.Circuit board 56 and antenna mounting panel 58 are electrically connected.Antenna component 55 received signals also are delivered to them on the circuit element that is installed on the circuit board 56.On the other hand, circuit element is to antenna component 55 suppling signals.To circuit board 56 and the 58 all requirements of antenna mounting panel is that they are electrically connected with the angle of inclination, and they can be made of the epoxy plate that bends to the angle of a solid, or are made of the circuit board 56 and antenna mounting panel 58 angled being placed in together of independent preparation.Have angle of inclination ground to settle circuit board 56 and antenna mounting panel in this way, they can by with glutinous bonding, welding, the mechanical fixation that connects, screw is installed and analog is placed in together, is with or without physical clearance between them.

Antenna component 55 can be an any kind, has a plurality of helical conductors, or only has the single mode of resonance of a helical conductor.

Optionally, circuit board 56 and antenna mounting panel 58 can be to make mechanicalness crimping then (crimp) separately.

Though not shown in Figure 31, also be suitable between antenna mounting panel 58 and circuit element placing barricade on the circuit board 56.Barricade can alleviate the mutual interference between them effectively.

Though the angle of the rake 60 between circuit board 56 and antenna mounting panel 58 can be according to the arbitrary decisions such as shape of housing, in order to make foreshortened length 61 maximizations, the angle θ that the front of circuit board 56 and antenna mounting panel 58 forms is 90 degree or is suitable more for a short time.For the height H that reduces the antenna mounting panel also can further reduce angle θ to spending less than 90.Yet too small if angle θ reaches, too near because the circuit element of antenna component and circuit mounting area 57 leans on, this causes the problem as the phase mutual interference.Therefore, between 70 to 100 degree, be suitable with angle initialization, consider intensity and workability even preferably keep vertical substantially angle.

In conventional equipment, circuit board 56 and antenna mounting panel 58 are indiscrete, but are assembled to one in the plate of single and same level.Opposite, structure is to be that antenna mounting panel 58 centers on 60 bendings of bent angle portion like this in Figure 31, and antenna component 55 and ground plate 59 are installed on this antenna mounting panel 58.

By to the circuit board 56 direction inclined antenna mounting panels 58 that the treatment circuit that comprises LSI and discrete component is installed, this structure usage space effectively on three-dimensional makes and has saved the space that is labeled as foreshortened length 61.This degree with foreshortened length 61 has reduced the length overall of circuit board, and the housing of these plates is held in realization or the size of this electronic equipment reduces.Especially, because these size and dimensions as its housing of device of portable terminal greatly depend on circuit board, can shorten the length of portable terminal and satisfy the requirement that size reduces with the space that foreshortened length 61 is saved.In the structure of conventional apparatus, various treatment circuits and antenna element are installed on the circuit board on a flat plane, and antenna element requires have a wide buffering of leaving circuit mounting area 57 to bring the interference that prevents its receiving circuit element.Because alleviated the mutual interference mutually with these circuit elements, the concrete enforcement structure with antenna mounting panel 58 of inclination can be dwindled buffer strip.Because this reason, the height H of upward bent antenna mounting panel 58 do not need the same big with foreshortened length 61.Though the thickness of the housing of these plates is accommodated in the height H of antenna mounting panel 58 decision and since a part of foreshortened length 61 be by the minimizing contribution of buffer strip and be not that each inch all changes height H into, what shortcoming requires housing to increase thickness does not almost have.Therefore, this embodiment reduces the whole volume that length can reduce the device as portable terminal by realizing the thickness that does not increase it.
