Webfront and back of the proposed SIW H-plane horn antenna design. Approximately symmetric half-power beamwidths in both E- and H-planes along with higher gain is obtained. Fig. 1: Slotted substrate integrated waveguide H-plane horn antenna; front (left) and back (right). II. DESIGN PROCEDURE This section discusses the design of the … WebCommonly the quadratic phase errors are used with t = 0.375 for the H-plane and s = 0.25 for the E-plane [1]. These values do not optimize the gain or directivity, since these are derived from approximations of the aperture dimensions that maximize the gain for a given axial length. This approach lead to
