摘要
应用时域有限差分法模拟同轴线馈电贴片天线的瞬态特性，分析了具覆盖层和空气隙的微带贴片天线，提取出谐振频率结果与实验结果吻合较好。求解了带宽和辐射方向图，并讨论了介质覆盖和空气隙对天线谐振频率和辐射特性的影响。
In this paper, the microstrip patch antennae are simulated with FDTD method to discuss the effect of superstrate and air gap. The resonant frequency are calculated as well. It is shown that the numerical results are identical with experimental results. The radiation pattern and bandwidth are also predicted and discussed.
