摘要
引入了一种崭新的天线概念—可重构天线。首先根据传统微带天线腔模理论定性地分析了微带可重构天线的工作机理 ,然后用时域有限差分 (FDTD)法对微带天线的可重构特性进行了仿真分析。仿真和分析表明 :矩形微带可重构天线当某一边长大于等于一个工作波长时 ,能够获得良好的可重构特性。
A new concept antenna, reconfigurable antenna, is introduced in this paper. Firstly qualitative analyses on the principle of microstrip reconfigurable antennas are done using microstrip antenna cavity theory. Then properties of some microstrip reconfigurable antennas are simulated using the finite difference time domain (FDTD) method. The results indicate that rectangle microstrip reconfigurable antennas can have good reconfigurability when the side lengths are greater than or equal to one operating wavelength.
