摘　　要：本文设计了一个工作于Ka频段的双频可重构微带缝隙天线。该可重构天线使用RF-MEMS开关来实现24GHz和30GHz两个工作频率之间的切换,且在这两个工作频率上都具有相同的输入阻抗、极化方向和辐射方向图。本文给出了天线的设计流程,最后仿真得到的结果与期望结果一致,达到了一般天线设计要求,可适用于多系统集成化应用中。A reconfigurable microstrip slot antenna is designed. This antenna uses RF-MEMS series switch to achieve frequency switching between 24GHz and 30GHz. The design process is presented in this paper, the same input resistance, polarization and radiation pattern of both frequencies is obtained. The whole model was simulated and the result was desirable. It reaches the common requirement of antenna and can be used in the application of multi-system integration.
