Moment Method Calculation of Reflection Coefficient for Waveguide Elements in a Finite Planar Phased Antenna Array

Abstract

A technique is presented for determining the aperture reflection coefficients for E-plane and H-plane scanned finite planar phased antenna arrays. The array elements are rectangular waveguide-fed apertures arranged in either a rectangular or triangular lattice and are located in an infinite ground plane. The formulation is such that an iris may be present at the waveguide- half space junction and the waveguides may be completely filled with dielectric. The method of moments is used to solve an integral equation for the unknown equivalent magnetic current distribution of each aperture.
