Fig. 5 A and Fig. 5 B is the concept map of the antenna assembly illustrating the comparison embodiment according to the present invention, and Fig. 5 C is the concept map of the antenna assembly according to embodiment of the present invention.

Being the antenna being transformed from slot antenna (slotantenna) according to the antenna assembly comparing embodiment, it is configured in multiple frequency bands radio signals while resonance.Generally, slot antenna is according to being structured with, i.e. form gap on the wall surface of waveguide, the surface of cylindrical conductor or flat conductor plate, and to cutler feed so that electric field can be formed in gap.In this configuration, slot antenna works as radiant body.This general slot antenna has been used in single frequency band rather than processes radio signal in multiple frequency bands.Will with reference to Fig. 5 A and Fig. 5 B illustration.

Fig. 5 A and Fig. 5 B is that the present invention first compares embodiment and second and compares embodiment respectively, respectively illustrates the slot antenna 30 with an open side.Slot antenna 30 is configured in low-frequency band resonance, due to mirror effect, has the gap length (D) shorter than the slot antenna with two closed sides.It is to say, have an open side slot antenna can at identical frequency band resonance, and length corresponding to have two closed sides slot antenna length about 1/2.

When having the slot antenna of two closed sides, gap has the length corresponding with λ/2 of the wavelength of the mid frequency of the first frequency band, in order at the first frequency band radiated radio ripple.When having the slot antenna of an open side, gap has the length that λ/4 of the wavelength with this mid frequency are corresponding.It is to say, the slot antenna with open side can have minimum size, this is because it can pass through have the radio wave that the gap radiation of short length is corresponding with the radio signal of low-frequency band.

Fig. 5 A is exemplified with when slot antenna 30 relation between impedance and electric current when the first frequency band radiated radio ripple.At this, dotted line indicates the size of impedance and the electric current that arrow instruction is flowed along gap.

First component 31 and second component 32 form gap (S).

The length (D) in gap (S) is corresponding to λ/4 of the wavelength of the mid frequency of the first frequency band.The value of the impedance (antenna assembly is by this impedance radiated radio ripple) of antenna assembly is about 377 ohm, and the open side 35 in gap carries out impedance matching.Owing to carrying out the impedance matching of antenna at about 50 ohm, so feed section 33 and a closed side 34 (D1) spaced a predetermined distance from.

Fig. 5 B is exemplified with the impedance when the antenna radiated radio ripple in the second frequency band of Fig. 5 A and electric current.The length (D) in gap is corresponding to λ/2 of the wavelength of the mid frequency of the second frequency band.The value of the impedance (antenna assembly is by this impedance radiated radio ripple) of antenna assembly is about 377 ohm, and the core on the length direction in gap carries out impedance matching.

Unless feed section 33 moves, otherwise feed section 33 corresponds to realize in the second frequency band the position of the impedance of about 300 ohm for the position of impedance matching in the first frequency band.On the contrary, the impedance matching position (D2) in the second frequency band separates predetermined length with the enclosure portion in gap.

Therefore, if the invariant position of feed section 33, then impedance matching it is difficult to allow slot antenna to have the efficiency higher than predetermined value in the second frequency band.

If it is to say, feed section 33 is positioned in the first frequency band to carry out impedance matching, then being difficult to carry out impedance matching at the second frequency band.Gratifying antenna performance is obtained at the second frequency band it is thus impossible to enough.

In order to solve this problem, it is provided that a kind of antenna assembly according to embodiment of the present invention as shown in Figure 5 C.With reference to Fig. 5 C, this antenna assembly is provided with the feed extension 36 extended out from feed section 33.

Feed extension 36 extends from feed section 33 so that when slot antenna works in the second frequency band, impedance can be about 50 ohm.It is to say, when slot antenna works in the first frequency band, feed section 33 transfers to the position that impedance is 50 ohm.Predetermined length (D3) is extended from feed section 33 in feed extension so that when slot antenna works in the second frequency band, impedance can be 50 ohm.

Antenna assembly according to the present invention can have such impedance matching, i.e. when not using balanced-to-unblanced transformer or duplexer, it is possible to realizes the antenna efficiency higher than predetermined value at multiple frequency bands.

Fig. 6 A is the concept map of the antenna assembly illustrating the mobile terminal according to first embodiment of the invention, Fig. 6 B is the concept map that the antenna assembly illustrating to Fig. 6 A with the addition of the example of protuberance, and Fig. 6 C is the figure of voltage standing wave ratio (VSWR) of the antenna assembly illustrating Fig. 6 A.

As shown in Figure 6A, antenna assembly 300 includes the first component 310, second component 320, feed section 330 and feed extension 360.

Each party in first component 310 and second component 320 can be configured to conductive member, and the first component 310 and second component 320 define the gap (S) of antenna 300.It is to say, the space between the first component 310 and second component 320 is used as the gap (S) of antenna assembly.The opening portion in gap (S) is referred to as opening 350.Due to the connection between the first component 310 and second component 320, the enclosure portion of gap (S) is referred to as adapter 340.

Length (D) from the opening 350 of gap (S) to adapter 340 is corresponding to λ/4 of the wavelength of the mid frequency of the first frequency band or λ/8.The length in gap (S) can change due to antenna feeding methods, the dielectric constant of the dielectric material of antenna or the capacitor of interpolation feed section.Such as, when causing antenna assembly to work in λ/4 mode of resonance due to the change of feed method, the length in gap can correspond to λ/4 of mid frequency.In order to make the smaller of antenna assembly 300, gap (S) can be bent, or gap (S) can have curved structure.

Such as, when the first frequency band is corresponding to the communication service bandwidth of GSM850, gap (S) is formed with the length of about 45～53mm.When the first frequency band is corresponding to the communication service bandwidth of LTE700, gap (S) is formed with the length of about 50～60mm.Consider the efficiency of antenna assembly, it is desirable to the width of gap (S) is at least 0.003 λ.

Each party in first component 310 and second component 320 only needs to be made of an electrically conducting material.In this embodiment, the first component 310 is implemented as the flexible printed circuit board with ground connection, and second component 320 is implemented as the frame of the inside for supporting mobile terminal.

Feed section 330 is to gap antenna feed electricity so that antenna assembly can at characteristic frequency resonance.More specifically, one end of feed section 330 may be coupled to a component in gap so that feed section 330 can form electric field in gap (S).

Can completely or partially be connected with each other according to feed method, feed section and component.

According to direct feed method, the feed section (referring to Fig. 4) extended from coaxial cable 252 can extend to another component to stride across gap (S) from a component.It is to say, according to direct feed method, one end of feed section may be coupled to a component, and the other end of feed section can extend to connect to another component.

According to couple feed method, one end of feed section may be coupled to a component, and the other end of feed section can separate with another component.

With reference to Fig. 6 A, feed section 330 extends from second component 320 to the first component 310.According to couple feed method, one end of feed section 330 is connected to second component 320, and the other end of feed section 330 and the first component 310 separate.

As shown in Figure 6A, feed section 330 is spaced a predetermined distance from adapter 340 so that due to feed section 330, the impedance of the mid frequency of the first frequency band can be about 50 ohm.Feed section 330 can include being implemented as the vent diverter with capacitor or inducer introduction row impedance matching.Vent diverter can control resistance, the real part of impedance.Such as, inducer can be controlled as has high resistance, but capacitor can be controlled as and have low resistance to perform impedance matching.Vent diverter can be embodied as lumped constant element on one end of feed section.

Preset distance is extended from feed section 330 in feed extension 360, make due to feed extension 360, the impedance of the mid frequency of the second frequency band can in 50 ohm, and making when antenna assembly includes three components, the impedance of the mid frequency of the second frequency band can in 50 ohm.The length of feed extension 360 can carry out suitable control for impedance matching so that antenna assembly 300 can work efficiently.Feed extension 360 can include the series element having capacitor or inducer to carry out impedance matching.Series element can control reactance, the imaginary part of impedance.Such as, inducer can be controlled as has high reactance, but capacitor can be controlled as and have low reactance to carry out impedance matching.Series element can be implemented as lumped constant element in a part for feed extension 360.That is, it is possible to arrange series capacitor in one end of feed extension, or series reactor can be arranged in a part for feed extension.

When including vent diverter or series element, by changing length or the shape in gap, antenna assembly can have the performance further enhanced.

Such as, when bridging condenser is arranged in feed section 330 and series capacitor is arranged in feed extension 360, due to the resistance reduced and reactance, the length in gap can be formed to correspond to about λ/8 of the center frequency-band of the first frequency band.Due to the contraction in length in gap, antenna assembly can be minimized.

Feed extension 360 is alternatively coupled to a surface of second component 320.Dielectric material can be disposed between feed extension 360 and second component 320.FR-3 and CEM-1 can be used as dielectric material.FR-3 is made up of the paper of multiple layers that are filled with epobond epoxyn, and CEM-1 is the synthetic material with the refill being filled with epoxy resin.Alternatively, dielectric material may be implemented as CEM-3, FR-4, FR-5 or GI.The CEM-3 being filled with epoxy resin has braiding glass cloth (wovenglasscloth) surface and the core of nonwoven ground glass fiber (non-wovenmattefiberglass).FR-4 is structured on the multi-layer braided glass cloth being filled with epoxy resin.FR-5 is structured in the multilamellar being filled with epoxy resin to be strengthened on braiding glass cloth.GI is structured on the multi-layer braided glass cloth being filled with polyimide resin.Alternatively, dielectric material may be implemented as printed circuit board (PCB) (PCB).

As shown in Figure 6A, feed extension 360 is alternatively coupled to a surface of second component 320.As shown in Figure 5 C, feed extension 360 can extend from feed section 330 so that when slot antenna works in the second frequency band, impedance can be about 50 ohm.

But, when antenna assembly as will be discussed later includes three components, there is additional resonance from the 3rd frequency band, cause strengthening at the second band impedance.Therefore, feed extension can extend (with reference to Fig. 5 C) according to the mode making impedance in the second frequency band can be about 150 ohm from feed section.

When the mid frequency of the second frequency band is about 1900MHz, the length with about 8～13mm can be formed as from the feed extension 360 that feed section is extended.Due to the electromagnetic effect of other parts from antenna assembly, this increasing length of feed extension 360 is big or reduces.Insulator or dielectric material can be disposed between feed extension 360 and second component 320.

Different from the above-mentioned situation on the surface that second component 320 is coupled in feed extension 360, feed extension 360 can separate to extend parallel to second component from second component.Implementation below shown in Fig. 7 B to Fig. 7 D will be explained.If feed extension and at least one component separate with this member parallel extend, then between feed extension and this component, there is Capacitance Coupled.Owing to this Capacitance Coupled changes the electric capacity of antenna assembly, the interval between feed extension and the component being arranged in parallel or the length of feed extension therefore can be controlled, in order to for controlling the characteristic of antenna.If feed extension is formed according to allowing to this capacity coupled mode of generation, then the length feeding extension can be shorter than the length in the embodiment shown in Fig. 6 A.

With reference to Fig. 6 B, except the first component 310, second component 320, feed section 330 and feed extension 360, antenna assembly 300 can also include the 3rd component 370.

Due to the radiation in the second frequency band, in the central part office of gap (S), the opening part occurred rather than at gap (S) occurs, and due to peripheral devices, antenna efficiency can reduce at the second frequency band.Therefore, antenna assembly 300 can also include the 3rd component 370 with at the threeth frequency resonance adjacent with the second frequency band.3rd component 370 is a kind of protuberance.

3rd component 370 may be implemented as conductive member, and can the side from the first component 310 and second component 320 extend.Such as, the 3rd component 370 can extend from the first component 310.As shown in Figure 6B, the 3rd component 370 can be formed by predetermined length, and wherein the part bending of the 3rd component 370 is parallel with the first component 310.3rd component 370 can be formed as having the length corresponding with λ/4 of the wavelength of the 3rd frequency.The length of the 3rd component 370 (from being connected to one end of another component to the other end) is corresponding to the 3rd frequency.2 when the 3rd frequency is 2100MHz, and the length of the 3rd component 370 is preferably about 20～25mm.During antenna tuning processes, the length of the 3rd component can increase or reduce.Such as, when the inducer as series element is added to the 3rd component a part of, the length of the 3rd component can shorten.If the contraction in length of the 3rd component, then can reduce the interference to other antenna being arranged in the mobile terminal with multiple antenna.

The figure (REF1) of Fig. 6 C middle and upper part is exemplified with the voltage standing wave ratio (VSWR) of the frequency of the antenna assembly according to Fig. 6 A.Even if as it can be seen, bandwidth is a bit narrow, also achieve good antenna performance at the first frequency band.But, at the second frequency band, voltage standing wave ratio (VSWR) is about 8, and this represents that antenna efficiency is low at the first frequency band in the second band ratio.

The figure (REF2) of the bottom in Fig. 6 C is exemplified with the voltage standing wave ratio (VSWR) of the frequency of the antenna assembly including the 3rd component according to Fig. 6 B.

As the antenna assembly of Fig. 6 B, antenna assembly can also include the 3rd component 370 with at the threeth frequency resonance adjacent with the mid frequency of the second frequency band.If the mid frequency of the second frequency band is about 1900MHz, then the 3rd component 370 can be formed such that the 3rd frequency can be about 2100MHz.In this configuration, shown in the figure (REF2) of the bottom in Fig. 6 C, antenna this add at the 3rd frequency resonance.Therefore, antenna assembly can form wide bandwidth at the high frequency band of the mid frequency and the 3rd frequency that include the second frequency band.

When antenna assembly also includes the 3rd component 370, there is additional resonance at the 3rd frequency band, thus enhance impedance at the second frequency band.Therefore, feed extension 360 can extend from feed section so that impedance can be about 150 ohm in the second frequency band.It is to say, antenna assembly has the surplus (margin) of impedance matching.More specifically, it is preferable to ground, at the second frequency band, impedance is about 50 ohm.But, even if impedance is about 150 ohm at the second frequency band, antenna assembly still can realize predetermined antenna performance.Additionally, antenna assembly also includes the surplus of the 3rd component impedance matching to have about 50～150 ohm at the second frequency band.

Fig. 6 D is the sectional view intercepted along the IV-IV line of Fig. 3, it is shown that have the mobile terminal of the antenna assembly shown in Fig. 6 A.

In the mobile terminal with monopole type, PIFA type or folded dipole type antenna, the component of antenna is separated by other electronic installation.Reason is that this reduction is because owing to the electronic installation arranged near antenna assembly causes electromagnetic property variable in order to prevent from reducing antenna efficiency.It is to say, mobile terminal needs the inner space with predetermined volume for installing antenna assembly.In the related, it is difficult to design mobile terminal, this is because mobile terminal should have sufficient inner space to install antenna assembly.

But, in the present invention, mobile terminal has the antenna assembly 300 being transformed from slot antenna.The antenna assembly 300 of the present invention has the efficiency of enhancing at multiple frequency bands.Additionally, even if electronic installation is disposed near the conductive member of antenna assembly 300, the performance of antenna assembly 300 does not also reduce.The ground connection as mobile terminal that reason is because in the component of antenna assembly 300 carrys out work.Another reason is because when the radio signal of the first frequency band, and electromagnetic wave radiates in the open side of gap (S).According to this structure, with time compared with the other type of antenna of the preferred embodiment of the present invention, mobile terminal need not internal radiation space.As a result, terminal body is made to thinner.Additionally, as shown in Figure 6 D, it is possible to achieve one has specially designed mobile terminal, and wherein the antenna mounting portion of this mobile terminal is more slim than other parts (display or battery mounting section).It is to say, the thickness that mobile terminal is configured such that mobile terminal reduces to its direction, upper and lower.Even if as it has been described above, formed in little space, the antenna assembly of the present invention can realize sufficient antenna performance and be not subjected to the impact of other electronic installation.

As shown in Figure 6A, the first component 310 can include the socket (socket) 219 that can electrically connect with external equipment.Even if the component defining gap (S) includes other electronics coupling part, antenna assembly can also maintain the performance higher than predetermined value.This can enable to design mobile terminal according to mode more freely.Additionally, due to all parts can be integrated each other, mobile terminal can reduce to less.

The inner space of the mobile terminal according to the present invention can be utilised more efficiently.With reference to Fig. 4 and Fig. 6 A, the first component 310 is for electrically connecting the button of the user input unit of mobile terminal with circuit board 350.Button is disposed on a surface of the first component 310, and display 310b is disposed on a surface of second component 320.Button and display 310b are formed according to predefined size, and are formed multiple parts assembled with one another.When multiple parts by assembled with one another, owing to assembling tolerance or dimensional tolerance, it is desirable to have the spacing distance for overdose space between parts.

In order to the tolerance (surplus) between parts and in order to user watch display time handle display, button and display 310b can be spaced apart in the longitudinal direction.With reference to Fig. 6 D, in this configuration, between the first component 310 and second component 320, gap (G) is formed.

In the present invention, this gap is used as the gap (S) of antenna assembly 300.It is to say, in the present invention, the gap (S) of antenna assembly 300 forms the gap location required in the terminal due to tolerance.Therefore, the inner space of mobile terminal can more effectively be obtained by.

Hereinafter, by not illustrating with the same or similar structure mentioned in Fig. 7 A to Figure 11, different structures will be only described.

Fig. 9 A to Fig. 9 C is the antenna assembly illustrating the mobile terminal according to third embodiment of the invention and the concept map according to the antenna assembly comparing embodiment.In this embodiment, multiple antenna is defined.First antenna device may be operative to above-mentioned slot antenna, and the second antenna assembly may be operative to monopole type antenna, dipole-type antenna or PIFA type antenna.

As shown in Figure 9 A, the first component 1210 and second component 1220 form the gap (S) of antenna assembly.Such as, the first component 1210 can be implemented as the flexible printed circuit board (FPCB) for the signal that user input unit produces is sent to controller.Second component 1220 may be implemented as the frame of the inside for supporting mobile terminal.

First antenna component is fed by the feed section 1230 being connected to circuit board 1250 by coaxial cable.Feed extension 1260 extends from the first feed section 1230.

The 4th component 1280 realizing the second antenna assembly is fed so that can radiate the radio signal of the 4th frequency band.4th component 1280 may be implemented as the conductive shell of the outward appearance forming terminal body.Can be fed by the second feed section 1290 that one end is connected to from another coaxial cable of circuit board 1250 extension with ground connection.According to this structure, the 4th component 1280 may be operative to monopole type antenna or dipole-type antenna.

First antenna device and the second antenna assembly are arranged to close to each other, and have ground connection independent of each other.It is to say, the ground connection of first antenna device is used as second component 1220, and the ground connection of the second antenna assembly is used as circuit board 1250.Can work independently of one another according to this structure, the ground connection of first antenna device and the ground connection of the second antenna.

When mobile terminal is provided with multiple antenna, in fact it could happen that the antenna problem to the isolation of antenna.But, in this embodiment, first antenna device and the second antenna assembly are configured with different radiation directions.It is to say, first antenna device has the first radiation direction, and the second antenna assembly has a perpendicular to the second radiation direction of the first radiation direction.

In a preferred embodiment of the invention, even if the operation of multiple antenna assemblies is MIMO or diversity system, mobile terminal can also reduce the mutual coupling between first antenna device (main antenna of sending side or reception side) and the second antenna assembly (sub antenna receiving side of MIMO or diversity system) and envelope correction coefficient.

At least one antenna in the multiple antenna assemblies being installed to mobile terminal is the slot antenna according to the present invention, it is possible to realize multiple antenna assembly in the space less than existing mobile terminal.It is to say, in a preferred embodiment of the invention, in the frame portion of mobile terminal, the first antenna device as slot antenna work is arranged near the second antenna assembly being implemented as monopole type, dipole-type or PIFA type.Alternatively, as described below, it is possible to by first antenna device and the second antenna assembly lamination each other.Here, frame portion refers to that the Outboard Sections from display unit of terminal body extends to the inner space of the housing of mobile terminal.

Second device is arranged to the surface covering first antenna 1200 '.It is to say, first antenna device and the second antenna assembly lamination each other.

Laminar structure due to antenna assembly, it is possible to freely arrange the various types of mechanical parts within mobile terminal, and the smaller of mobile terminal can be made.

Owing to the first antenna device according to the present invention is not subjected to the impact of surrounding mechanical parts, it is possible to more freely design mobile terminal.

Fig. 9 C illustrates according to the antenna assembly comparing embodiment, and wherein each party in first antenna device and the second antenna assembly is implemented as monopole type antenna, dipole-type antenna or PIFA type antenna.Each party in first antenna device and the second antenna assembly can include carrier 12 85 ' and form the conductive pattern 1280 ' on a surface of carrier 12 85 '.

This antenna assembly should with electronic installation 250 and 310 " ' separate, this is because this antenna assembly is subject to the impact of surrounding mechanical parts.When multiple antenna assembly, each antenna assembly all should be separated with electronic installation.This can cause the restriction of the inner space for installing antenna assembly of mobile terminal.Additionally, the design of mobile terminal is subject to the restriction of antenna assembly, therefore, it is difficult to make mobile terminal miniaturization.

Being different from the mobile terminal of Fig. 9 C, the antenna assembly of Fig. 9 B reduces antenna efficiency almost without the electronic installation due to periphery.Therefore, it can freely design mobile terminal.

Figure 10 is the concept map of the antenna assembly illustrating the mobile terminal according to four embodiment of the invention.

In the 4th embodiment, mobile terminal is provided with multiple slot antenna.In this antenna assembly, the first gap (S) can be formed by the first component 1310 and second component 1320, and the second gap (S) can be formed by the 4th component 1310 ' and the 5th component 1320 '.

3rd component 1370 can the side from the first component 1310, second component the 1320, the 4th component 1310 ' and the 5th component 1320 ' extend out.3rd component 1370 may be operative to the device relevant with the impedance matching of slot antenna, and may be operative to cause the device at another frequency resonance.

Feed section 1330 is formed multiple.More specifically, feed section 1330 can include the first feed section 1330 for the gap (S) formed by the first component 1310 and second component 1320 is fed and the second feed section 1330 ' for the gap (S) formed by the 4th component 1310 ' and the 5th component 1320 ' is fed.First feed section 1330 is provided with the first feed extension 1360, and the second feed section 1330 ' is provided with the second feed extension 1360 '.

For the impedance matching of the mid frequency corresponding to high frequency band, feed extension 1360 and 1360 ' extends out from feed section 1330 and 1330 '.

In this embodiment, the ground connection of the first slot antenna is used as the first component 1310, and the ground connection of the second slot antenna is used as the 4th component 1310 '.Therefore, it can realize independently of one another the ground connection of each antenna.

In a preferred embodiment of the invention, even if the operation of multiple antenna assemblies is MIMO or diversity system, it is also possible to reduce the mutual coupling between the first slot antenna (main antenna of sending side or reception side) and the second slot antenna (sub antenna receiving side of MIMO or diversity system) and envelope correction coefficient.

Figure 11 is the concept map of the antenna assembly illustrating the mobile terminal according to fifth embodiment of the invention.

The back casing 202 ' covered by the battery container 203 of mobile terminal has gap (S).With this gap (S) for benchmark, the top of back casing 202 ' is used as the first component 1410, and the bottom of back casing 202 ' is used as second component 1420.In this embodiment, back casing 202 ' is formed by conductive material, and has gap (S).The dielectric material with predetermined dielectric constant can be used to fill this gap (S).

Feed section 1430 extends from second component 1420 to the first component 1410, and feeds extension 1460 from feed section 1430 definite length extended.

In this embodiment, terminal body can have the back casing 202 formed by conductive material as slot antenna.

Back casing 202 ' owing to forming the outward appearance of mobile terminal is used as the component of antenna assembly, and a part for antenna assembly is arranged on the edge of terminal body.This internal structure allowing to design mobile terminal according to greater compactness of mode.

Figure 12 A is the concept map of the antenna assembly illustrating the mobile terminal according to sixth embodiment of the invention, and Figure 12 B is the axonometric chart of the antenna assembly of Figure 12 A, and Figure 12 C is the sectional view of antenna assembly of Figure 12 B.

In a preferred embodiment of the invention, conductive material the conductive shell 202 formed can be arranged to the side surface covering mobile terminal.Conductive shell 202 forms the outward appearance of terminal body.If the outward appearance of mobile terminal is formed by conductive shell 202, then mobile terminal can keep enough intensity and less thickness, and can have special outward appearance.In this embodiment, back casing 202 is used as conductive shell 202.Alternatively, procapsid 201 is used as conductive shell 202.

Conductive shell 202 can include the first conductive shell 202a and the second conductive shell 202b.First conductive shell 202a can be disposed in the side of terminal body or upper end or lower end, and the second conductive shell 202b can be formed cover the side surface of mobile terminal rather than cover with the first conductive shell 202a.If antenna assembly is formed as multiple, then the first conductive shell 202a can also be formed as multiple.

Dielectric material is formed between the first conductive shell 202a and the second conductive shell 202b.It is to say, when being arranged in by dielectric material between the first conductive shell 202a and the second conductive shell 202b, the first conductive shell 202a and the second conductive shell 202b is spaced apart.Ground connection according to this structure, the first conductive shell 202a and mobile terminal separates, thus being in electromagnetism quick condition.Therefore, even if the first antenna device including the first component and second component being arranged near the first conductive shell 202a, also reduce due to the first conductive shell 202a electromagnetic effect to first antenna device caused, thus prevent the performance of first antenna device to reduce.

Owing to the first conductive shell 202a and the second conductive shell 202b is spaced apart, it is possible to prevent the reduction of the antenna performance caused due to body effect.Body effect refers to when human contact or the change of the antenna performance of generation when the specific part of mobile terminal.Such as, dead grasp (deathgrip) (phenomenon that when a kind of specific part at mobile terminal is by the grasped of user, acceptance rate reduces) is considered body effect.As shown in Figure 12 B, the first conductive shell 202a is disposed in upper end or the lower end of mobile terminal, and the user's contact being likely to affect the performance of antenna assembly occurs over just on the second conductive shell 202b.According to this structure, it is possible to reduce the reduction of the performance of the antenna assembly caused by body effect.

Conductive shell 202 is provided with the opening 202c that the gap (S) with first antenna device connects.As it has been described above, opening 202c can fill with dielectric material.Can be separated by opening 202c and socket 219 according to this structure, the first conductive shell 202a and the second conductive shell 202b.Owing to opening 202c utilizes conductive shell 202 to be formed, therefore the open area of first antenna device can extend up to the outside of terminal body.

As it has been described above, the first component 1510 of first antenna device and second component 1520 can be implemented as conductive member, and the gap (S) of antenna assembly can be limited.It is to say, the space between the first component 1510 and second component 1520 is used as the gap (S) of antenna assembly.Feed section 1530 is formed so that the antenna assembly including gap (S) at the first band resonance, and can feed extension 1560 and be formed so that antenna assembly can at the second band resonance.

The radiation of the second frequency band carries out at the core of gap (S), rather than carries out at the opening 202c place of gap (S).This may result in antenna efficiency and reduces at the second frequency band due to surrounding devices.Therefore, antenna assembly can also include the 3rd component 1570 with at the threeth frequency resonance adjacent with the second frequency band.3rd component 1570 operation is a kind of protuberance.3rd component 1570 is formed parallel with the first conductive shell 202a.

The compatible portion 1531 being configured to carry out impedance matching at special frequency band can be formed between feed section 1530 and feed extension 1560.

With reference to Figure 12 C, carrier 1585 can be formed between first antenna device (ANT1) and the second antenna assembly (ANT2,1580).The irradiator of the second antenna assembly 1580 may be implemented as the conductive pattern 1581 being printed onto on carrier 1585.

Carrier 1585 is the dielectric material with dielectric constant, it is possible to be implemented as FR-3 and CEM-1.FR-3 is made up of the paper of multiple layers that are filled with epobond epoxyn, and CEM-1 is the synthetic material with the refill being filled with epoxy resin.Alternatively, carrier 1585 may be implemented as CEM-3, FR-4, FR-5 or GI.The CEM-3 being filled with epoxy resin has braiding glass cloth (wovenglasscloth) surface and the core of nonwoven ground glass fiber (non-wovenmattefiberglass).FR-4 is structured on the multi-layer braided glass cloth being filled with epoxy resin.FR-5 is structured in the multilamellar being filled with epoxy resin to be strengthened on braiding glass cloth.GI is structured on the multi-layer braided glass cloth being filled with polyimide resin.Alternatively, dielectric material may be implemented as printed circuit board (PCB) (PCB).

Second antenna assembly 1580 is formed send at the 4th frequency band and receive (transmitting-receiving) signal.Conductive pattern 1581 as irradiator can be formed as having the electrical length corresponding with the 4th frequency band.

According to antenna type, conductive pattern 1581 can be connected to substrate to process radio signal by feed connector or grounding connector.Such as, when monopole type antenna device, conductive pattern 1581 can be fed by feed connector and ground connection.On the other hand, when PIFA type antenna assembly, the conductive pattern 1581 being provided with feed connector and grounding connector may be connected to substrate.

Feed connector (F) can be configured to electrically connect feed section with conductive member, and can be configured to according to EM (electromagnetism) feeding classification, conductive member be fed.For this, feed connector (F) can include at least one in feeder panel, feeding clip and feed line.Owing in feeder panel, feeding clip and feed line is electrically connected to another, it is passed to the conductive member of transmitting-receiving (send and receive) radio signal from the electric current (or voltage) of feeder equipment offer.Here, feed line can include the micro-strip that is printed on substrate.

With reference to Figure 12 A, it is possible to even form compatible portion 1582 between machine 1583 at conductive pattern 1581 (irradiator) and feed.Compatible portion 1582 may be implemented as series element or vent diverter.When compatible portion 1582 is implemented as series element, thus it is possible to vary reactance, i.e. the imaginary part of impedance.Such as, inducer can be controlled as has high reactance, but capacitor can be controlled as and have low reactance to change the impedance at special frequency band.On the other hand, when compatible portion 1582 is implemented as vent diverter, thus it is possible to vary resistance, i.e. the real part of impedance.Such as, inducer can be controlled as has high resistance, but capacitor can be controlled as and have low resistance to change the impedance at special frequency band.

Mobile terminal can use radio communication and wireless base station to communicate.Such as, cell phone can use 850MHz, the cellular telephone band of 900MHz, 1800MHz and 1900MHz (such as, main global system for mobile communications or GSM cellular telephone band) communicates.Communication even should carry out at the 1.92～2.17GHz serviced for WCDMA (WCDMA).Additionally, communication even should carry out at 704～960MHz of B13 or the B17 communication service for LTE (Long Term Evolution).In order to the mobile terminal according to the preferred embodiment of the present invention provides communication service at multiple frequency bands, antenna assembly includes gap (S), feed section, feed extension grade.
