| 摘 要： | 本文利用矩量法与并矢格林函数相结合,研究了背腔式窄缝天线在有耗介质中的特性。对于矩阵单元的双重级数,采用泊松求和公式改善了级数的收敛性;对于矩阵单元的二重积分,分别采用积分中值定理及椭圆积分予以简化。本文的数值结果分别给出了有耗介质及天线结构参数对输入阻抗的影响,为天线设计提供了依据。

| Abstract: | The study of characteristics of the cavity-backed slot antenna in a lossymedium is given by using the moment method and dyadic Green's functions. The Poisson summation formula is used to convert the double series of the elements into a more rapidly converging series, and the integration middle value theorem and elliptic integral are used to simplify the double integral of the elements. Numerical results show the effects of the lossy medium and antenna parameters on input impedance, which could be used in designing cavity-backed slot antenna. |
