Abstract
A Ka-band horn for transmitting and receiving information between a ground station and a satelitte includes three sections. The throat segment of the horn is adapted for coupling to a feed and includes circular, alternating grooves and webs that are of a widening type created by linearly increasing the width of the grooves in the direction of the horn's aperture. The throat corrugations are for matching the impedance of adjacent sections of the horn. A middle segment includes an up-angle flare section and a down-angle flare section each having dual depth corrugations that enable the horn to achieve a near-HE11 mode at the aperture of the horn. The final segment of the horn is a truncated, smooth-walled, cone.
