摘要
设计了TD-SCDMA终端的PIFA天线,定出了天线的结构尺寸,并进行了开槽改进。该天线结构紧凑,可以很方便地用于3G无线通信的终端设备,实用性很强。利用HFSS软件进行了天线建模,性能仿真和优化,最终得到增益为G=4.330 3 dB,效率达到45.471%,电压驻波比小于2的带宽大于100 M的天线。
The Planar Inverted F-shaped Antenna designed in TD-SCDMA terminal device. The dimension of PIFA is calculated and chamfered on it's surface. This antenna has a compact structure that is used easily in terminal device of 3G. It has a strongly practicality. After building model, simulation of performance and optimization of dimension are used in HFSS software. Finally, acquired antenna's gain is 4.330 3 dB, efficiency is 45.471%, the bandwidth is great than 100 MHz when VSWR〉2.
