摘要
本文通过实验研究对MEMS开关供电线对方向图可重构天线方向图的影响进行了分析,并采用电磁带隙(EBG)结构对开关供电线的影响进行了抑制,改善了基于MEMS开关方向图可重构天线的辐射图形,验证了前期工作理论工作的正确性。
In this paper, we rearsch the influnce of MEMS switch's bias-line on radiation-reconfigurable antenna's performance. Via EBG structure, the effect of the bias-line is restrained, and the radiation pattern of the antenna is improved. That agrees well with the former theoretical work.
