Abstract

This paper describes the ultra-wideband horn antenna design operating in quasi TEM mode. The antenna consist of a triangular 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 1.57 to 12.85 GHz bandwidth a 11 to 14 dBi gain. The proposed antenna was manufactured and the measured reflection coefficient results show an operation frequency range between 1.48 and 10.12 GHz, agreeing very well with simulations.
