Abstract :
In this paper we will present the new design of TEM double-ridged horn antenna, resulting in a better VSWR and improved gain of antenna. A cavity back and a new technique for tapering the flared section of the TEM horn antenna are introduced to improve the return loss and matching of the impedance, respectively. By tapering the ridges of antenna both laterally and longitudinally it is possible to extend the operating frequency band while decreasing the size of antenna. The proposed antenna is simulated with two commercially available packages, namely Ansoft HFSS and CST microwave studio. Stimulation results for the VSWR, radiation patterns, and gain of the designed TEM horn antenna over the frequency band 2-18 GHz are presented.
