摘要
针对传统蘑菇型CRLH(composite right/left-handed)微带天线带宽窄的问题,设计了一种基于CRLH TL的蘑菇型宽带小型化天线,并使用三维全波电磁仿真软件CST就接地板对微带天线电性能的影响进行了数值分析。仿真和实测结果表明,该天线在Wi-Fi和Wi MAX频段呈现良好的全向辐射特性,相对带宽达到82%(S11≤-10 d B)。
A broadband miniaturization antenna for Wi-Fi and WiMAX is designed to solve the problem of narrow bandwidth for the conventional mushroom microstrip antenna based on CRLH transmission line.And the influence of ground plate on the electric performance of microstrip antenna is analyzed by CST software.The simulation and testing results show that the antenna has a good omnidirectional radiation performance for Wi-Fi and WiMAX and is well matched with a 82% relative impedance bandwidth （S11≤-10 dB）.
