Reconfigurable Microstrip Antenna Design Based on Microgenetic Algorithm

摘要: 提出了一种微带可重构天线方案,并将微遗传算法与时域有限差分法相结合,对天线的可重构能力进行了探索。在特定工作频率条件下,优化设计了一方向图可重构天线。优化结果表明,在工作频率为6.5 GHz时,该微带可重构天线能够通过三种工作状态在特定平面内实现方向图扫描,同时也表明了遗传算法在可重构天线设计中的巨大潜力。

Abstract: A scheme of reconfigurable microstrip antenna is presented, and the reconfigurability of the antenna are explored using microgenetic algorithm(MGA) in conjunction with the finite-difference time-domain(FDTD) method. A pattern reconfigurable antenna with a fixed operation frequency is optimized and designed. The optimized results indicate that a capability of pattern scanning within a single plane can be achieved by using three switchable states at 6.5 GHz. This work also shows the potential application value of GA in the optimizing and designing of reconfigurable antenna.
