Abstract

This paper presents the design of the dual-band flat antenna operating at 2.45 GHz and 5.25 GHz. This antenna is designed for polarization diversity of wireless LAN application (IEEE 802.11 a/b/g/n). The antenna is operated at dual-band with dual-polarization capability. The prototype flat antenna consists of a plate, a T-step slot, a rectangular slot, a rectangular ring strip, an air gap and a ground plane. The simulation process is done by using the CST Microwave Studio software. The results show the isolations higher than 15 dB that is satisfied the system requirement. The flat antenna is designed to obtain the unidirectional radiation pattern. The maximum gain is higher than 7 dBi.

双频平面天线，极化分集，高隔离

本文介绍了工作频率为2.45 GHz和5.25 GHz的双频平面天线的设计。该天线是为无线局域网应用(IEEE 802.11 a/b/g/n)的极化分集而设计的。天线工作在双波段，具有双极化能力。原型平面天线由极板、t阶槽、矩形槽、矩形环带、气隙和接地面组成。仿真过程采用CST Microwave Studio软件完成。结果表明，隔离度大于15 dB，满足系统要求。平面天线的设计是为了获得单向辐射方向图。最大增益大于7dbi。
