Abstract :
A technique for developing a new type of feed horn with the same radiation characteristics as a metallic corrugated horn is presented. This horn antenna with low back and sidelobe levels can be used as a substitute for a metallic corrugated horn with added advantages of high gain, low cross polarization, low cost, and light weight. The convenience of the photolithographic technique for fabricating simulated corrugated surfaces opens the possibility of the mass production of such horns with simpler methods.<>
