应用于WLAN的小型微带天线

内容简介：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，该天线的尺寸和性能可以在手机WLAN通信系统得到良好的应用。

Abstract：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×16.5 mm. The simulation results show that the size and performance is suitable for application of mobile WLAN communication system.
