A Solution for a Wide Aperture Reactively Loaded Antenna Array.
Abstract
This report considers an array of wide aperture reactively loaded antennas, specifically, an N element array of closely-spaced waveguide-backed rectangular slots radiating into a half-space region. Only the center slot is fed and the other slots are parasitically excited. The parasitic slots are reactively loaded by short-circuit waveguides. By varying the positions of the short circuits, a directive beam can be steered through 180 deg in space. The solution uses the moment method applied to the integral equation for the equivalent magnetic current in the aperture region and a numerical integration technique. Solutions for seven, nine, and fifteen element aperture arrays are given. A computer subroutine which generates the aperture halfspace admittance matrix is described and listed. (Author)
