本文提出了一种计算效率高的矩量公式，用于径向线槽天线的全波分析和设计。该方法的效率是基于内部问题（电大圆腔）格林函数的一个特别表示，它被分成平行板波导贡献和边缘效应贡献的总和，在径向模式方面展开。结合实例，对所提出的格林函数展开的收敛速度进行了分析和数值研究。此外，在完整的RLSA上与商业通用MoM软件进行了比较，以证明我们方法的准确性和效率
Here a computationally efficient method of moments (MoM) formulation is presented for the full-wave analysis and design of radial line slot antennas (RLSAs). The method efficiency is based on an ad-hoc representation of the internal problem (electrically large circular cavity) Green's function, which is split into the sum of a parallel plate waveguide contribution and a rim effect contribution, expanded in terms of radial modes. The convergence rate of the proposed Green's function expansion is investigated both analytically and numerically with the aid of some examples. Furthermore, comparisons with a commercial general purpose MoM software were performed on a complete RLSA to demonstrate the accuracy and the efficiency of our approach
