Abstract

An impedance matching technique for RF-MEMS switch based microstrip patch antenna is considered in this paper to improve the return loss and impedance bandwidth. It is observed that the impedance matching can be improved by using a lumped element based matching network. The impedance matching technique is performed by using Smith Chart and verified through Ansoft HFSS simulations. An inductor of 1.62 nH in series with CPW transmission line can be used as a lumped element matching network to improve the return loss upto -18dB at resonant frequency of 5 GHz with adequate impedance bandwidth.

基于RF-MEMS微带贴片天线的阻抗匹配

本文提出了一种基于RF-MEMS开关的微带贴片天线的阻抗匹配技术，以提高天线的回波损耗和阻抗带宽。结果表明，基于集总元的匹配网络可以改善阻抗匹配。采用Smith图进行阻抗匹配，并通过Ansoft HFSS仿真进行验证。1.62 nH电感与CPW传输线串联可作为集总元件匹配网络，在5 GHz谐振频率下，在有足够阻抗带宽的情况下，可将回波损耗提高至-18dB。
