摘要： Feed horn apparatus for use in a multiple-feed antenna system. The present invention comprises a corrugated feed horn and an antenna array or cluster of feed horns arranged in a hexagonal lattice pattern. The feed horn comprises a hexagonal aperture formed by a circular-to-hexagonal transition section a corrugated section disposed adjacent to the circular-to-hexagonal transition section, a tapered section disposed adjacent to the corrugated section, and an input section having an input/output port disposed adjacent to the tapered section. The corrugated feed horn has good beam pattern symmetry, low cross-polarization, and sidelobe levels, along with an increased horn aperture area. As a result, the efficiency of the corrugated feed horn is improved by transitioning from a circular to the hexagonal aperture.

摘要： 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.
摘要翻译：用于在地面站和卫星台之间发送和接收信息的Ka波段喇叭包括三个部分。喇叭的喉部适于联接到进给器，并且包括圆形的，交替的槽和腹板，其是通过沿喇叭孔的方向线性增加槽的宽度而形成的加宽型。喉咙波纹用于匹配喇叭的相邻部分的阻抗。中间段包括上角喇叭形部分和下角喇叭形部分，每个具有双重深度波纹，使得喇叭能够在喇叭的孔处实现接近HE11的模式。喇叭的最后一个部分是一个截头圆滑的圆锥体。
