Abstract

This paper presents the hybrid method combined with the method of moments and the finite element method for the radiating part to enhance the bandwidth of the double-layer corporate-feed waveguide slot array antenna. Next, the radiating part is designed by using the hybrid method and the bandwidth for VSWR less than 1.5 is improved from 9.2% to 18.0% by lower Q, appropriate arrangement of resonance frequencies and triple resonance.
