Parametric Analysis of Multi Source Feeding Flare Rolling and Corrugating Effects for H-Plane Horn RadiatorAbstract
In this paper, radiation characteristics of H-plane sectoral horn antenna are treated systematically by investigation of the multi source feeding, flare wall rolling and corrugating effects. The analytical regularization method (ARM) is used to solve the problem of E-polarized wave diffraction in a fast and accurate way. The numerical procedure is initially verified by the analytical solutions, and the calculated field patterns are presented for the selected horn antenna configurations. Proper choices of the geometrical parameters, such as source position, back wall shape, multi source feed, metal thickness, and ridged and corrugated flares are proposed for the designers to reach high directivity, narrow beam, and suppressed side and back lobe levels.
