摘　　要：提出一种基于MEMS开关的可重构矩形缝隙环天线设计。其关键部件之一是射频微波MEMS开关,选取了接触式MEMS开关。该天线为用共面波导馈电的多频率可重构天线,通过多个MEMS开关来改变矩形缝隙环天线的拓扑结构,按照一定的规则控制开关可实现多频率可重构。其结构简单,剖面低,易于与电路集成。A design of reconfigurable rectangular slot ring antennas with MEMS switches is proposed in paper. The antenna is frequency-reconfigurable with a coplanar waveguide feed. The Contact Cantilever MEMS swit are chosen as the control parts of the antenna. With different arranges of the switch-states to change topological structures, the antenna is easy to realize frequency-reconfigurable feature. And simulation res this ches the ultshas proved its performance.
