A New Technique for Scanning by the Pattern of a Two-Element Phased Array of Rectangular Waveguides

Abstract

An easy and efficient technique without the necessity of using phase shifters is suggested for scanning by the main lobe of a two-element periodic phased antenna array of rectangular waveguide sections. The oscillations are excited and the power distributed in the waveguide channels by the surface wave of a planar dielectric waveguide with a metal substrate. The possibility is shown to simultaneously scan within two planes through changing the propagation direction of the surface wave in the dielectric waveguide
