应用于WLAN的小型微带天线

Small-size microstrip antenna for WLAN

为了满足手机无线局域网(WLAN)通信技术的要求,设计了一个三频段单极子贴片天线,通过2个L形支路产生双频辐射。并用软件对该天线进行仿真优化,实现了2.4 GHz、5.2 GHz和5.8 GHz三频段的同时工作,而且该天线结构简单,由L形贴片组合形成,体积小,所占面积为14.5 mm×16.5 mm。仿真结果表明。

In order to meet to the requirements of mobile wireless LAN（WLAN）communication technology,a triple-band monopole patch antenna was designed,which can generate double-frequency radiation by two L-shaped branches. An electromag-netic model of the designed antenna was developed for simulation and optimization. It can works simultaneously in three frequen-cy bands at 2.4 GHz,5.2 GHz and 5.8 GHz. The antenna has a simple structure,which is composed of L-shaped patch,and only occupies an area of 14.5 mm＆#215;16.5 mm. The simulation results show that the size and performance is suitable for application of mobile WLAN communication system.
