Abstract
The main antenna and auxiliary antenna are respectively provided at the top and tail of mobile phone, and the main antenna and auxiliary antenna have different radiation patterns and different received field strengths according to the same transmitting signals. One end of SPDT switch is connected to the mobile phone circuit part while the other end is in switchable connection to the main antenna and auxiliary antenna. The mobile phone antenna structure of the utility model sets up two antennas with different radiation patterns and different received field strengths, and uses the switch to select one antenna having better signals. Because the two antennas are respectively provided on top and tail of mobile phone, it is conducive to realize the peculiar diversity technique at mobile phone terminal using the space diversity technique and beam diversity technique, and the receiving performance of mobile terminals is improved.
Description
Technical field
The utility model relates to a kind of handset structure, is specifically related to a kind of antenna structure of mobile phole.
Background technology
At present, at moving communicating field, especially in the network interface card product, diversity antenna technology is finding broad application aspect the elevator system gain.For the mobile phone terminal use, receive if can use a plurality of antennas, mean that signal quality will effectively be improved, data throughout increases, and the permissible call distance is farther, and reduces the multipath effect in the urban environment.
But, on mobile phone terminal,, add the restriction in space because the mainboard size has determined the main polarization components of antenna, realize very difficulty of two antenna orthogonal polarizations completely, cause on mobile phone is used, realizing very difficulty of polarization diversity technique.Simultaneously can bring many relevant issues, comprise cost, size and to the influence of systematic function etc., cause diversity antenna technology in mobile phone, not to be applied always owing in mobile phone, insert a plurality of antennas.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of antenna structure of mobile phole is provided, and diversity antenna technology is applied to mobile phone terminal, improves the communication quality and the performance of mobile phone terminal.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of antenna structure of mobile phole, it is characterized in that, comprise bearing for one and receive and the main antenna of launch mission, an auxiliary antenna of bearing the reception task and a single-pole double-throw switch (SPDT), described main antenna and auxiliary antenna are positioned over the top and the afterbody of mobile phone respectively, described main antenna has different antenna patterns and different received field strengths with auxiliary antenna to same transmitting, described single-pole double-throw switch (SPDT) one end connects the mobile phone circuit part, and the other end switches described main antenna of connection and auxiliary antenna.
In antenna structure of mobile phole described in the utility model, described main antenna and auxiliary antenna adopt dissimilar antennas.
In antenna structure of mobile phole described in the utility model, employing unipole antenna of described main antenna and auxiliary antenna, one is adopted the PIFA antenna.
In antenna structure of mobile phole described in the utility model, described main antenna adopts of the same type but the antenna of different cabling modes with auxiliary antenna.
In antenna structure of mobile phole described in the utility model, described main antenna and auxiliary antenna adopt unipole antenna or PIFA antenna simultaneously.
Implement antenna structure of mobile phole of the present utility model, compared with the prior art, its beneficial effect is: by the different antennas different with received field strength of two antenna patterns and that antenna of selecting to have better signal by diverter switch are set, two antennas are separately positioned on the top and the afterbody of mobile phone, thereby be beneficial to space diversity reception to communicate and beam diversity technology and realized the distinctive diversity technique of mobile phone terminal, improved the receptivity of mobile phone terminal.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of the utility model antenna structure of mobile phole.
Embodiment
Embodiment one
As shown in Figure 1, antenna structure of mobile phole of the present utility model comprises bearing for one and receives and the main antenna 1 of launch mission, an auxiliary antenna 2 and a single-pole double-throw switch (SPDT) 3 of bearing the reception task.Main antenna 1 and auxiliary antenna 2 are positioned over the top and the afterbody of mobile phone respectively, like this, just avoided the high galvanic areas of antenna, reduced the electric current coupling between the antenna, there is battery to isolate simultaneously between the double antenna, reduced the coupling of free space, the hole, ground of mainboard also effectively reduces the coupling of surface wave, practice draws, the double antenna of Fang Zhiing like this, isolation can reach more than the 15dB in the 900M frequency range, can reach more than the 20dB in the 1800M frequency range, provides the good technical guarantee to the application of diversity technique.
Same the transmitting of 2 pairs of base stations of main antenna 1 and auxiliary antenna has different antenna patterns and different received field strengths, and single-pole double-throw switch (SPDT) 3 connects mobile phone circuit part 4 and switch also that preferable antenna of selective reception signal all the time between main antenna 1 and auxiliary antenna 2.
When an antenna is in the more weak even disarmed state of received signal, another antenna will receive the much higher signal of intensity probably, select by the switching of single-pole double-throw switch (SPDT) 3, guarantee that mobile phone receives preferable signal.
In order to realize that 2 pairs of same transmitting of main antenna 1 and auxiliary antenna have different antenna patterns and different received field strengths, main antenna 1 and auxiliary antenna 2 adopt dissimilar antennas, as an employing unipole antenna, the combination of antennas that another adopts PIFA (the dull and stereotyped inverted F antenna of Planar Inverted F Antenna) antenna or adopts other type.
Embodiment two
Present embodiment and embodiment one are basic identical, and difference is: main antenna 1 adopts same type but the antenna of different cabling modes with auxiliary antenna 2, realizes that 2 pairs of same transmitting of main antenna 1 and auxiliary antenna have different antenna patterns and different received field strengths.All adopt the antenna of unipole antenna, PIFA antenna or other type as main antenna 1 and auxiliary antenna 2, but main antenna 1 adopts different cabling modes respectively with auxiliary antenna 2.
