Abstract

In this paper 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 on radial modes. Comparisons with a commercial general purpose MoM software were performed on a complete RLSA to demonstrate the accuracy and the efficiency of the approach
