Abstract:
1. A method for making a horn antenna, said method comprising the steps of: fabricating a dielectric first board defining first and second broad sides, and also having at least a first transverse dimension adjacent a feed end of said first board, said first board defining a conductive horn on said first broad side thereof and a feed structure on said second broad side thereof adjacent said feed end of said first board, said feed structure including a strip conductor adjacent said feed end of said first board; fabricating a dielectric second board defining first and second broad sides, and also having at least said first transverse dimension adjacent a feed end of said second board, said second board defining on said first broad side a conductive horn including a feed region adjacent said feed end of said second board, said second board defining an aperture which is registered with said strip conductor when said second broad side of said first board is offset-juxtaposed with said second broad side of said second board; offset-juxtaposing said second broad side of said first board with said second broad side of said second board, with said strip conductor feed structure adjacent said aperture, and an offset between lateral edges of said first and second boards, to thereby generate a single horn element.
