[Abstract]:With the rapid development of mobile communication industry and mobile devices, mobile terminals are becoming smaller and more broadband. The current frequency bands include GSM900 / GSM 1800% DCS / WIFI / Bluetooth / WLAN. At the same time, the LTE technology will be widely used in the fourth generation mobile communication system because of its high speed data transmission rate. The smaller and smaller space and more work mode make the design of mobile phone antenna more demanding. In this paper, the development history of mobile phone antenna and the research status of mobile phone antenna are introduced, and the future development trend of mobile phone antenna is forecasted. Then the basic working principle, radiation parameters and testing tools of microstrip antenna are introduced. In the third chapter, the common antenna of mobile phone is introduced, and the miniaturization of antenna and the method based on multi-frequency are introduced. In this paper, two new mobile phone antennas are proposed and analyzed in detail. One is the inverted F antenna (IFA verted-F Antenna), which is composed of extra parasitic elements and resonant elements, which can effectively reduce the size of the antenna by space folding. The volume of the antenna is about 60% smaller than that of the same antenna. The other antenna is the broadband LTE monopole antenna, which is loaded with CRLH to broaden the bandwidth of the antenna, while limiting the volume to a smaller range. The monopole antenna works in the GSM / TD-SCDMA / TD-LTE / WLAN band. Finally, the processing test of the two antennas shows that the performance test results are good and have great application potential.
