摘要
采用基于二级离散复镜像法的矩量法,分析了同轴馈电的任意形状微带天线的输入阻抗.该方法采用二级离散复镜像方法求解空间域的格林函数,与直接数值积分方法相比,提高了计算格林函数的速度.采用简化的附加模基函数模拟贴片与探针相连处的电流分布,降低了计算的复杂度.计算了两个不同形状的微带贴片天线的输入阻抗,所得的计算结果与实验结果吻合良好.
The impedance of coax-fed arbitrary shape micrestrip patch antenna is investigated by the moment method. The two-level discrete complex image method is used to compute the spatial Green＇s Function, and thus improves the speed to compute Green＇s function compared with the direct integral method. The simplified additional mode is introdueted to simulate the current distribution near the probe-to-patch junction with the complexity decreased. The intut impedance of two different shape microstrip patch antennas is computed and the numerical result agrees well with the experimental result.
