Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
In the design of mobile communication terminal, radio sensitivity is a very important index, is related to the stability problem of the Distance geometry signal of communication.Improve the radio sensitivity of system, the design of antenna is most important.In the appearance design of current a lot of mobile communication terminals, manufacturer, in order to pursue external styling more attractive in appearance and hand touches texture, often needs to adopt the positions such as the frame of metal material design mobile communication terminal and bonnet.The use of large-area metal material also makes the operational environment of terminal inner antenna become worse and worse, causes serious impact to the reception of antenna and emitting performance.
Be described for current panel computer.Current panel computer is much all designed with metal edge frame 1 and is partly the bonnet 2 of metal material, as shown in Figure 1.In Fig. 1, the nonmetallic materials such as the part A of bonnet is made up of metal material, and remainder B is made up of nonmetallic materials, such as plastics.Wherein, the bonnet A of metal material is often as battery flat bonnet, and run user dismounting is to change battery; The bonnet B then often fixing assembling of nonmetallic materials, generally do not allow user to dismantle, the antenna of panel computer is just laid in the position corresponding with the bonnet B of nonmetallic materials usually, such as, be laid in dotted line frame region 4 as shown in Figure 1.The bonnet B of the nonmetallic materials in the antenna left and right sides can also arrange sound chamber 3 further, with external playing audio signal.
For mobile communication terminals such as current panel computer and mobile phones, its complete machine thickness often pursues more Bao Yuehao, usually requires to be limited in about 10mm.After the thickness of such removing display screen, casing and circuit board, antenna also only has 3mm many to the distance of circuit board.In addition, be all metal material around antenna, therefore operational environment is very poor, brings very large difficulty to the design of antenna.
The present embodiment is specifically described for the bluetooth of 2.4GHz frequency range or WiFi antenna.
Because the metal around antenna is more, therefore antenna cabling is easy to form resonance with peripheral part metal at multiple frequency, thus affects antenna at the reception of 2.4GHz frequency and emitting performance.For the loop aerial that performance in existing antenna design is relatively good, its cabling as shown in Figure 2, network analyzer is tested, although this loop aerial its voltage standing wave ratio in 2.4-2.84GHz frequency range can reach about 2, but due to the impact by surrounding metal, its actual testing efficiency is very low, only has about 10%.
In order to improve the performance of antenna, reduce the impact that it is subject to surrounding metal environment, the present embodiment proposes the Antenna Design thought of two-layer wiring, as shown in Figure 3, Figure 4, namely adopt two-layer cabling to form described antenna, and two of antenna tie points are defined as respectively feedback point 8 and place 9, for being communicated with (for bluetooth or WiFi antenna with the holding wire of mobile communication terminal internal circuit board is corresponding with ground wire, should specifically correspondingly with the Bluetooth circuit on circuit board or WiFi circuit connect), to transmit radio signal.
The present embodiment walks out one section of ground wire 5 specially, the place 9 described in connection on the ground floor cabling (representing ground floor cabling with solid line in Fig. 3, Fig. 4) of antenna; Second layer cabling (being represented by dotted lines second layer cabling in Fig. 3, Fig. 4) is formed feeder line 6, and be communicated with described feedback point 8, two-layer cabling is contacted by via hole 10 and connects, the bluetooth formed thus/WiFi antenna is owing to there being a special ground wire, thus for antenna provide one with reference to ground, this reduces interference and the impact of this antenna of other metal pairs generation around, and then be conducive to wireless receiving and dispatching performance and the stability of lifting mobile communication terminal.
The antenna of the present embodiment can adopt cathode copper material to make, and preferably adopts flexible PCB FPC to be made.Ground wire 5 for ground floor cabling can be designed to various shape, such as shown in Figure 3 horizontal U-shaped or approximate horizontal Y type etc. as shown in Figure 4, concrete shape can be that reserved space size, shape and the test effect comprehensive consideration of antenna is determined according to mobile communication terminal inside.As two tie points of described antenna---feedback point 8 and place 9, both can layer same with ground floor cabling, be such as all arranged on upper epidermis; Also can layer same with second layer cabling, be such as all arranged on layer.The present embodiment preferably leaks copper at upper surface, the feedback point 8 described in formation and place 9, as shown in Figure 3, Figure 4.Conveniently place 9 is connected with difform ground wire 5, can walk one section of straight ground wire 12 and be connected between described ground wire 5 and place 9; Its one end can be contacted connection by via hole 10 with the ground wire 5 being positioned at upper epidermis for the feeder line 6 being positioned at layer, the other end of feeder line 6 then can be directly connected with the feedback point 8 being positioned at upper epidermis by the mode of via hole or employing welding.Due in theory, when the length of antenna is suitable with the wavelength of its radio signal that will receive, the transmitting and receiving conversion efficiency of antenna is the highest, therefore, the frequency (can be conversed the wavelength of corresponding radio signal by the centre frequency of the radio signal of transmitting and receiving) that the length of antenna can will transmit and receive signal according to it is decided.But in fact, in the antenna environment of the mobile communication terminals such as current mobile phone and panel computer, due to the restriction by terminal inner space, the whole wavelength that the length of antenna will reach radio signal is substantially impossible, therefore, the feed line length of antenna is preferably designed at least 1/4 of the radio signal wavelength that will receive at antenna by the present embodiment, at least 1/4 of the radio signal wavelength that feeder line 6 Design of length being about to be positioned at lower surface will receive at described antenna, thus while satisfied laying space and the beamwidth of antenna require, relatively high conversion efficiency can be obtained.For bluetooth or the WiFi antenna of 2.4GHz frequency range, the length of described feeder line 6 can design at about 31.2mm, to obtain relatively high transmitting and receiving conversion efficiency.
Certainly, also one section of feeder line 7 can be walked specially in ground floor cabling, as shown in Figure 3, Figure 4, be connected between feedback point 8 and the feeder line 6 of the second layer, via hole specifically can be adopted to realize the connection of two-layer feeder line, to be contacted with the ground wire 5 of ground floor cabling by via hole 10 by one end of second layer feeder line 6 and connect, the other end of feeder line 6 passes through via hole 11 and contacts with the feeder line 7 of ground floor cabling and connect, and then connects described feedback point 8 by the feeder line 7 of ground floor cabling.When adopting this Antenna Design mode, in order under the prerequisite meeting limited antenna laying space, obtain relatively high transmitting and receiving conversion efficiency, preferably the total length of the feeder line 6 of the second layer and the feeder line 7 of ground floor cabling is arranged at least 1/4 of the radio signal wavelength that antenna will receive.For bluetooth or the WiFi antenna of 2.4GHz frequency range, preferably the total length of two sections of feeder lines 6,7 is designed at about 31.2mm, obtain relatively high conversion efficiency to enable the antenna of formation.
Meet design requirement in the antenna laying spatial dimension that mobile communication terminal is reserved to make the total length of feeder line 6 and feeder line 7, feeder line 6 can be designed to linear or circuitous shape etc., concrete shape can be determined according to the actual laying situation appropriate design of mobile communication terminal, and the present embodiment is not limited in above citing.
The antenna of the stereochemical structure form using the design of above-mentioned two-layer wiring is laid in panel computer product, such as be pasted onto the inner side of the bonnet B of nonmetallic materials, in dotted line frame region 4 such as shown in Fig. 1, and making two of antenna tie points---feedback point 8 and place 9 are assembled to after on casing at bonnet B, just can be communicated with ground contact with the holding wire on circuit board, thus realize panel computer to the reception of radio signal and transmitting, complete communication task.
The antenna of three-dimensional for the employing designed by the present embodiment Wiring structure is tested on network analyzer, the standing-wave ratio of antenna can reach about 2 in 2.4-2.84GHz frequency range, efficiency also can reach more than 40%, compare the antenna of conventional monolayers Wiring structure, the antenna of the present embodiment is obviously reduced by the impact of surrounding metal, and wireless performance obviously improves.
Bluetooth/WiFi antenna and the tradition of the employing two-layer wiring version design proposed by the present embodiment adopt the bluetooth/WiFi antenna of individual layer annular Wiring structure form design to carry out test and comparison, shown in its result can see table:
| Antenna type | By the distance that bluetooth is listened to the music | The WiFi signal intensity of the same focus of same position | The WiFi speed of surfing the Internet of the same focus of same position |
| Individual layer loop aerial | About 30 meters | About-85dBm | 2-5Mbps |
| Two-layer wiring antenna | 50-60 rice | About-79dBm | 11Mbps |
Be can clearly be seen that by the test result of upper table: the panel computer using the antenna of two-layer wiring version, when being listened to the music by bluetooth, maximum distance can reach more than 50 meters, and using the panel computer of traditional individual layer loop aerial, the maximum distance of being listened to the music by bluetooth only has about 30 meters.In WiFi performance, use same focus, panel computer is placed on same position and tests, use the panel computer of two-layer wiring antenna to search the signal strength signal intensity of this focus about-79dBm, speed of surfing the Internet can reach more than 11Mbps; And the signal strength signal intensity using the panel computer of individual layer loop aerial to search out only has-85dBm, speed of surfing the Internet only has 5Mbps at most.
Tested by reality and clearly illustrate, the antenna of the two-layer wiring structure that the present embodiment proposes is less by the impact of surrounding metal, and performance will be better than the antenna of conventional monolayers cabling conceptual design far away.
Certainly, except bluetooth or WiFi antenna can adopt above-mentioned two-layer wiring structural design mode, be suitable for for same for the mobile communication antenna linking mobile communications network.The antenna of this structure not only can design in panel computer product, equally also can design in other mobile communication equipments such as smart mobile phone, to improve the wireless performance of equipment.
It should be noted that; the above is only a kind of preferred implementation of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
