Smart radome improves reflector antenna directivity

A numerical optimization procedure is applied to two dimensional model of cylindrical reflector antenna arbitrarily located inside a circular cylindrical dielectric radome. If the radome thickness has been optimized, then varying the radome radius and the reflector position has a small effect on the directivity. However, the feed position should be corrected with respect to the free-space optimum after finding the best thickness. The optimization code is based on solving an integral equation by means of the regularization technique, guaranteeing a desired accuracy

Modelling a resistive-reflector antenna by the complex source-dual series approach: the 2-D case of H-polarization

The simulation of reflector antenna is normally conducted under an assumption of the perfect conductivity of reflector. This paper presents an analysis of resistive reflector beamforming using modified method of regularization for solving the scattering from a curve resistive strip. Besides, to simulate a directive feed in equally accurate manner, the Complex Source Method is used
