Abstract
Design and analysis of Ka-band hard-horn feeds for excitation of quasi-opti cal amplifiers have been performed. A computer program based on the mode-ma tching technique has been developed in order to determine the aperture fiel d distribution for pyramidal hard horns. This program is used to perform pa rametric studies and to optimize hard-horn performance such as its bandwidt h and efficiency. Simulation and measurement results for a 31-GHz hard-horn feed are presented.
