Electromagnetic Simulations for an Axisymmetric Gregorian Reflector System for a Space Deployed Inflatable Antenna

Abstract

An axisymmetric array-fed confocal parabolic Gregorian reflector system for potential space deployment is explored. The antenna utilizes a planar array located near the vertex of the primary reflector. Numerical electromagnetic simulations based on the multilevel fast multipole method (MLFMM) were used to analyze and optimize the antenna parameters for fixed on-axis peak directivity performance.Simulations of the radiation pattern performance of a dual reflector system with a 2.4m diameter primary reflector operating at Ku band are presented.
