摘要
设计了一种新型的集成RF-MEMS开关的混合分形可重构天线,该天线为加载了1阶Koch曲线的1阶Sierpinski三角垫片结构。仿真结果表明:所设计的天线在MEMS开关全闭合和全断开的状态下分别具有多个不同的工作频带。详细地分析了天线的重构特性,按照仿真模型在高阻硅片上运用微电子工艺制作出了天线样品。对样品进行了测试,最后比较和分析了测试结果。
New type of reconfigurable fractal antenna is designed, in which Koch curve loaded Sierpinski gasket integrated with RF-MEMS switches. Simulation results show that the antenna has several different operation bands respectively when the MEMS switches keep on and off. Detailed analysis of the reconfigurable proper- ty is presented. Samples of the designed antenna are fabricated on a high-resistivity silicon substrate by microelectronic technique. Finally the experimental results are offered as well as analysis and explanations.
