Abstract
A comprehensive study of the coating on the inner walls of a horn antenna is very beneficial for minimizing unnecessary losses while maintaining the same beam shape. An analytic method to investigate ohmic losses is presented. Based on the analytic investigations, guidelines are provided for low-loss designs of lossy material coatings for horn antenna beam shaping. Experimental results in support of the theory are also presented.<>
