At first with reference to Fig. 1 and 2, at first describe according to mobile radio communication apparatus of the present invention, for example mobile cellular equipment 20.Cellular device 20 schematically comprises shell 21 with the first half 46 and the latter half 47 and by the main dielectric substrate 67 of for example printed substrate (PCB) substrate of shell carrying.For example, with respect to being used in renovating or slide lid housing in many cell phones, illustrated shell 21 is fixed shells.Yet, also can use these and other shell configuration.
As skilled in the art will appreciate, and as discussed further below, the multiple circuit 48 of dielectric substrate 67 carryings, for example microprocessor, memory, one or more transceiver (for example honeycomb, WLAN etc.), audio frequency and power circuit etc..Preferably, shell 21 also carries the battery (not shown), is used for to circuit 48 power supplies.
In addition, audio frequency output transducer 49 (for example loud speaker) is carried by the first half 46 of shell 21, and links to each other with circuit 48.Preferably, shell 21 also carries for example one or more user's input interface units of keypad 23 and so on, and user's input interface unit links to each other with circuit 48.Other example of user's input interface unit comprises roller (scroll wheel) 37 and back (back button) 36.It will be appreciated, of course, that and also can use other user's input interface unit (for example writing pen and touch screen interface) among other embodiment.
As further discussing hereinafter, cellular device 20 also schematically comprises the antenna 45 in the latter half 47 that is carried on shell 21, and antenna 45 comprises the conducting wire pattern on the dielectric substrate 67.By antenna 45 and the latter half 47 adjacency of shell 21 are placed, the distance when advantageously having increased the use phone between antenna and the user's head helps to meet suitable SAR requirement.
More specifically, the user can hold the first half of shell 21 usually, very near head, makes the ear that audio frequency output transducer 49 directly is close to the users.Yet the latter half 47 of the residing shell 21 of audio frequency input transducer (for example microphone) does not need the mouth of directly being close to the users, and typically away from user's mouth.That is to say that audio frequency is imported the mouth that transducer keeps being close to the users not only can be uncomfortable for the user, and under some environment, can make user's voice distortion.In addition, the latter half 47 that antenna 45 is placed on latch housing 21 can also advantageously make the brain of antenna away from the user.
Another important benefit that antenna 45 is placed on the latter half 47 of latch housing 21 is, can reduce the influence of the obstruct of user's hand to antenna performance.Therefore that is to say that the user holds the middle and upper part of honeycomb telephone shell usually, compare with near the situation antenna is installed in the latter half 47 of shell 21 that the user more may be placed on their hand the top of this antenna.Therefore, by antenna 45 being placed on the latter half 47 places of latch housing 21, can realize more reliable performance.
Another benefit of this configuration is, for one or more auxiliary I/O (I/O) device 50 that will be carried on shell the first half 46 places provides more space.In addition, by antenna 45 is separated with auxiliary I/O device 50, can reduce interference between the two.
Just as skilled in the art will recognize, some examples of auxiliary I/O device 50 comprise the WLAN that is used to provide the WLAN communication function (Bluetooth for example
TM, IEEE 802.11) and antenna and/or be used to provide global position system (for example GPS, the Galileo etc.) antenna of positioning function.Other example of auxiliary I/O device 50 (for example comprises the second audio frequency output transducer, the loud speaker that is used for speakerphone operation) and be used to provide pick-up lens, the electric equipment connector (for example, USB, headphone, secure digital (SD) or storage card etc.) of digital camera function.
Should be noted that to be used for assisting the term " I/O " of I/O device 50 to represent that these devices can have input and/or input function here, but two kinds of functions needn't be provided in all embodiments simultaneously.That is to say that for example, the device such as pick-up lens can receive only the light input, and headphone jack can only provide audio frequency output.
When at first pressing or encouraging alternate function key 25, following line unit 26 also can be used for input " * " symbol.Similarly, when at first encouraging alternate function key 25, space bar 27, switch key 28 and backspace key 30 are respectively applied for input " 0 " and " # ".Just as skilled in the art will recognize, keypad 23 also schematically is included in and dials transmission key 31, end key 32 and quick (the being menu) key 39 that uses in the cellular calls.
In addition, the symbol arrangement on each key 24 becomes top line and end row.When the user does not at first press alternate function key 25 and when pressing key 24, the symbol in the input end row, and import symbol in the top line by at first pressing alternate function key.As shown in Figure 2, many symbol keys 24 be arranged in send and the first three rows of the keypad 23 that end key 31,32 is following in.In addition, arrange the letter character on each button 24, to limit the QWERTY layout.That is to say that the letter on the keypad 23 occurs with the form of triplex row, the character in every row has order and the relative position identical with standard QWERTY keypad.
Each row (comprising fourth line function key 25-29) of button is arranged as five row.Has figure notation by at first encouraging alternate function key 25 to visit (promptly 1 to 9) on many symbol keys 24 of second, third in first, second and the third line and the 4th row.As mentioned above, just as skilled in the art will recognize, also as finding on the conventional keys formula phone, with following line unit, space bar and the switch key 26,27,28 of input " * ", " 0 " and " # " combine the telephone keypad layout of standard that this group has been pressed key definition respectively by at first encouraging alternate function key 25.
Therefore, mobile cellular equipment 20 not only can be advantageously used for traditional cellular phone, can also be advantageously used in sending and/or receive data (for example e-mail data) by honeycomb or other network (for example internet).Certainly, in other embodiments, can use other keypad configuration.As what one of ordinary skill in the art will recognize that, repeatedly knock (multi-tap) or predict that input pattern (predictive entry mode) can be used to key in Email etc.
With reference now to Fig. 3 to 10,, the typical implementation of antenna 45 is discussed.Preferably, antenna 45 is multiband antennas, and the transmission and the receiving feature of enhancing is provided on a plurality of operating frequencies.More specifically, designing antenna 45 with the impedance matching that high-gain is provided, needs, and satisfies the SAR requirement that is suitable on wide relatively bandwidth and a plurality of cellular band.For example, antenna 45 preferably is operated on five frequency bands, be global system for mobile communications (GSM) frequency band of 850MHz, GSM frequency band, DCS frequency band, PCS frequency band and the WCDMA frequency band of 900MHz (promptly going up), but antenna 45 also can be used for other bands/frequencies to about 2100MHz.
Shown in Fig. 7 to 10, though antenna also can realize that for conserve space, antenna 45 can be advantageously with three dimensional realization with two dimension or plane embodiment.Antenna 45 schematically comprises the first 61 on the PCB 67.Second portion 62 is wound to L shaped dielectric extension (dielectric extension) or antenna fixing holder (retainer frame) 63 from PCB 67, and L shaped dielectric extension or antenna fixing holder 63 comprise the vertical components 51 that outwards stretch from PCB 67 and outwards extend and be in outer outstanding part (overhang portion) 68 on the adjacent part of PCB from vertical component.In certain embodiments, if desired, sidewall 55 can also be positioned on the opposite end of L shaped dielectric extension 63, so that additional support (seeing Fig. 7 and 9) to be provided.
Tuning branch conductors 72 has first end that links to each other with main loop conductor 64 between first and second branches, first end separately.That is to say that first end of tuning branch conductors 72 is linking to each other with main loop conductor 64 along certain the some place on the length between first and second branch conductors 70,71.The position of branch conductors 72 between part 77 and 78 can be changed easily, and frequency parameter can be do not had a strong impact on.In this example, main loop conductor 64 is roughly rectangle, has first side that comprises part 75-78 and gap, second side 74 and respect to one another first and second ends 79,80 relative with first side.Shown in Fig. 7 to 10, the order wire circuit path that can use printing or form pattern forms first and second parts 61,62 of antenna 45.
In illustrated embodiment, though first branch conductors 70, second branch conductors 71 and tuning branch conductors 72 first end separately link to each other with first side of main loop conductor 64 respectively, other configuration also is fine.For example, first end of tuning branch conductors 72 can link to each other with one of second side 74 or first and second ends 79,80.
As mentioned above, the second portion 62 of antenna 45 can be placed on the vertical component 51 of L shaped dielectric extension 63.This advantageously allows significantly to reduce antenna 45 and always contain the surface on the top side of PCB 67 (being circuit).In addition, the part of main loop conductor 64 can also be wound up on the outer outstanding part 68 of dielectric extension 63, with further saving space.Yet should be noted that just as skilled in the art will recognize, in certain embodiments, if enough free spaces are arranged, can realize antenna 45 (that is, first and second parts 61,62 are in the same plane) according to two-dimensional approach, and the 3D configuration that also can use other.
Part 74-80 limits main loop conductor 64.Just as skilled in the art will recognize, first branch conductors 70 can link to each other with signal source 54 under the situation of using or do not use passive matching network.Preferably, second branch conductors 71 links to each other with ground under the situation of not using matching network, and tuning branch conductors 72 is floated (that is, not linking to each other with signal source 54 or ground).
In general, branch 70,71 and 72 length are used to set the work centre frequency.Branch conductors 70 and 72 square complications (square meandering) or back and forth (back-and-forth) pattern be to can be used in the tuning feature that changes electrical length, wherein electrical length changes centre frequency.In addition, the difformity of branch 70,71,72 (that is tuning feature) can be used to the frequency that provides different.For example, except indentation shown in Fig. 3 and linear, other geometry that can be used for these branches comprises branch 41 (Fig. 4 B) of zigzag or triangle indentation 40 (Fig. 4 A), band etc.As what one of ordinary skill in the art will recognize that, various other shapes and combination thereof also can be used to the frequency characteristic that provides different.
The part 73 of main loop conductor 64 also is used for the Control work frequency.Multiple shape and/or cut-outs can be used for part 73.This tuning feature for example can comprise hair clip shape 94 (Fig. 5 E), indentation 95 (Fig. 5 F) and the zigzag 96 (Fig. 5 G) of " dog bone " shape 90 (Fig. 5 A), bear dog bone-shaped 91 (Fig. 5 B), hair clip shape 92 (Fig. 5 C), two hair clip shape 93 (Fig. 5 D), band.In addition, in certain embodiments, the part of main loop conductor 64 not only, and whole main loop conductor 64 also can adopt one of aforementioned shapes or other shape.
As what one of ordinary skill in the art will recognize that,, then can use the annular pattern of creating the tuning level of additional resonance if need circuit element to adjust input impedance and/or spread bandwidth in the specific embodiment.If enough free spaces are arranged, then can in suitable length, use straight line portion.Therefore yet typically, for built-in cellular device antenna, especially for the model of compactness, the space is of great rarity, and one of above-mentioned shape (or other) will be preferred.
The width and the shape of part 74 influence antenna gain.The length of part 74 also influences to some extent to operating frequency.Yet, should be noted that the length of part 70,71,72 and 73 (that is the length of entire antenna 45) also influences operating frequency as under the situation of typical dipole antenna.
In addition, part 74 can also have groove, sticking patch (patch) etc.Sticking patch can be used to increase surface area, thereby part 74 can be carried out shaping to wave beam.Should be noted that under cellular situation, should preferably make wave beam depart from phone, that is, vertical with the plane of PCB 37.For example, the width of antenna 45 can approximately be 7cm or littler, and the height of first 61 can approximately be 1 to 3cm, and the height of second portion 62 can approximately be 1 to 3cm, and this depends on given implementation.Certainly, can also use other size.
About the S11 impedance operator in the antenna 45, for wide bandwidth is provided, need be in the matched well on the interested frequency range.Therefore, as what one of ordinary skill in the art will recognize that, need dwindle S11 circle and the circle that will dwindle moves to the 50Ohm central point.The other parts of zone 73 and antenna 45 can be used to dwindle and/or mobile S11 circle, and preferably, this realizes in distributed mode.In addition, the matching network of antenna 45 and meanders also can be used for the S11 circle is shifted to required 50Ohm central point.According to as mentioned above of the present invention, owing to the S11 circle that dwindles advantageously can be moved to the 50Ohm point, so the center of the S11 that dwindles circle is not very crucial.
In general, above-mentioned antenna 45 allows to use multiple shape and length that suitable electrical length and CURRENT DISTRIBUTION is provided.Some shapes are simple delay lines, and other shaped design influences the electric current in the specific region.As mentioned above, suppose that the space is unrestricted, then many above-mentioned shapes and geometry are dispensable.Yet under the limited space environment of Wireless Telecom Equipments such as cell phone, above-mentioned antenna features is particularly advantageous in the multiplex (MUX) and makes the performance that provides required on the frequency band.
