城垛式线天线的研究

Investigation in Rampart Wire Antennas

本文对城垛式窄导线天线和城垛微带线天线进行了分析,采用了自由空间的 Green 函数和几何镜象时自由空间的 Green 函数分别构成积分方程,然后用矩量法求出电流分布,进而求出天线的远区辐射场.最后给出了几种毫米波段城垛式微带天线的实例与实验结果.

The asymtotic and geometric imaginary representations of Green function in free space are employed,respectively,for formulating the integral equations of the current distribution of rampart wire antennas.Then these equations are solved by the MM.The current distributions and the far field patterns are calculated.Finally,several samples of these antennas are designed,fabricated and tested. The experimental results are presented.
