Antennas are devices used to transmit and receive electromagnetic energy to and from free space. The electric and magnetic fields around antennas vary based on the location of the field point and the excitation impressed upon the antenna terminals. There are two major types of antennas widely used in radar and communication systems: linear wire antenna, center-fed by a transmission line, and electromagnetic horn antenna fed by a waveguide. In this paper, we present the radiation patterns of pyramidal horn and calculating the optimum values that maximize the horn directivity. These pyramidal horns are widely used as feeds for reflector antennas.
