摘要：PCT No. PCT/CA96/00646 Sec. 371 Date Mar. 24, 1998 Sec. 102(e) Date Mar. 24, 1998 PCT Filed Sep. 26, 1996 PCT Pub. No. WO97/12252 PCT Pub. Date Apr. 3, 1997This application relates to a compact broadband horn antenna. The antenna has a septum in the horn adjacent one side thereof. One embodiment consists of abutting, wedge-shaped, dielectric members having conducting coatings. A particular feed arrangement has a primary segment partitioned into quadrants with each quadrant having a conducting septum extending forwardly into a secondary section, to provide field uniformity. In an embodiment useful at frequencies above 1 GHz the septum curves upwardly at the horn mouth and is supported by an absorbing structure located just above the mouth of the horn. The other end of the septum is supported at the horn feed and the septum is otherwise unsupported along its length.
