摘要：

运用混合矩量法-物理光学法分析了组合导体平台附近线天线的电磁辐射特性,对线天线采用窄带结构建模,计算时整个区域都选用RWG基函数,避免选用其他形式的基函数,从而简化计算,并推导出计算公式。利用该方法计算了几种导体平台前线天线的辐射特性,通过和MoM、FEKO计算结果的对比,数值结果验证了混合方法的可行性与有效性。

Abstract:

A hybrid MoM-PO method is proposed to analyze the EM properties of wire antennas mounted near combining conducting objects with the wire antenna modeled by narrow strip configuration.The RWG basis function is used in the whole area,and no more other basis functions are necessary,which simplifies the formula derivation.The calculation equations are deduced.Finaly,numerical examples are given to show the accuracy and efficiency compared with the results of FEKO and MoM.

Key words: combining conducting objects;hybrid MoM-PO method;narrow strip;wire antenna
