T形双频天线的电磁兼容特性

内容简介：设计了一种双T形单极子天线,适用于2.4 GHz/5.2 GHz双频无线局域网业务.该天线是由两个不同尺寸的T形辐射单元构成单极子天线,分别产生工作在双频段的两个谐振模式,并且具有较好辐射特性.使用CST对天线进行仿真,研究了单极子的尺寸以及接地板尺寸对天线性能的影响,并且研究了天线周围的金属物质对天线性能的影响.

Abstract：A simple printed double-T monopole antenna is proposed for dual-frequency WLAN operations in the 2.4 GHz and 5.2 GHz bands. The antenna comprises two stacked T-shaped monopole of different sizes,which generate two separate resonant modes for dual-frequency operations. Good radiation characteristics have been obtained. This paper studied the effects of varying the monopole dimensions and the ground-plane size on the antenna performance. The effects of placement of additional metallic substance around the antenna have also been studied.
