Abstract

This paper describes the design of a wideband horn antenna operating in quasi TEM mode. The antenna consists of a triangular conductive plate with an inclination angle above a ground plane and directly feed by a coaxial cable. Broadband characteristics, radiation pattern, high gain and small reflection coefficient were achieved. Its performance analysis and main parameters effects were obtained by using ANSYS HFSS® software. In the numerical analysis, an optimized model was obtained in 2.52 to 16.3 GHz band with a 10 to 12 dBi gain. The reflection coefficient was measured and the results were consistent with simulations.
