Abstract

A complete tool for analyzing the mutual coupling in nonuniform (interleaved) array antennas consisting of rectangular aperture radiators is discussed. It relies on deriving the coupling admittances between arbitrarily located apertures via a two-dimensional interpolation scheme. Realistic radiators are accounted for through their scattering matrix evaluated by means of full-wave analyses. The method yields accurate results while greatly reducing the computation time. Its validity is demonstrated against measurements done on a medium-sized, interleaved, nonuniform array of cavity-backed apertures.
