Design of A Double-Ridged Horn Antenna

Peng Xu, Jiongchen Li

Open publisher page 0 citations

Abstract

In this paper, a systematic design of a double-ridged horn antenna is presented. The double ridge profile is approximated with a piecewise linear curve and the ridge gap is determined from an exponential taper in the wave impedance. The location of the coaxial probe and the size of the back cavity are optimized for the widest bandwidth. The reflection coefficient, gain and phase patterns of the horn are analyzed. The designed horn has reflection coefficient of less than -10dB and gain of 9-18dB at 9-33GHz.
