  1. Study of Gregorian feed for MeerKAT: Design and Advantages Mr. Stéphanie Alphonse. Supervisors: Prof. K.D. Palmer, Dr. Dirk de Villiers Electrical and Electronic Engineering Department, University of Stellenbosch Problematic Offset Gregorian is a reflector antenna which structurally and analytically complex to design due to the number of geometric parameters. Methods Fast analytical technique approximation has been used to find out the effect of the gain of the reflector by changing parameters. A Plane Wave Spectrum approach is proposed to overcome limitation. Fig .1: MeerKAT Prototype Create a GUI to help users understand the characteristics and advantages of using Dual Offset Gregorian reflector.
