A NOVEL SPATIAL IMAGES TECHNIQUE FOR THE ANALYSIS OF CAVITY BACKED ANTENNAS

Abstract

This paper describes a new contribution to the analysis of arbitrary shielded circuits and antennas of complex shapes, in the frame of the intergal equation (IE) and Method of Moments formulation (MoM). The technique is based on the spatial image approach and a new specially truncated set of images is developed to enhance the convergance behavior of the series involved. Results show that, with the new specially truncated series of images, convergence is achieved very fast. In this paper simulated results obtained with the new approach are compared with measurments.
