Abstract :
A method is presented for enhancing the efficiency of integral equation solutions for antennas. In this paper, a folded coaxial guide junction, proposed to be part of a below the feed inductive load, is analyzed. Scattering parameters for the folded coaxial guide junction are developed to replace the coupling of the field accounted for by a coupled integral equation at the aperture joining two coaxial guides. Numerical results are shown to agree well with measurements of cascaded folded coaxial guide junctions.
