Abstract :
A method for designing a pyramidal horn with optimum gain and a phase center that is insensitive to horn rotation over a wide frequency band is presented. The optimum gain comes out to be about 14 dB; ways to increase the optimum gain are suggested. The design is based on a far-field formulation and is useful for common applications. However, a parallel procedure based on a near-field formulation and using more exact gain expressions can be developed.<>
