Abstract :
The polyrod antenna (or the dielectric-rod antenna) has been known for some time. It is used primarily for its simplicity and unique pattern characteristics. The most interesting characteristic of this antenna is that the radiation pattern can be controlled not only by the cross section, dielectric properties, and length, but also by shaping its axis. By shaping the rod axis, various patterns can be obtained, some of them very useful. The antenna described paper has a typical polyrod pattern in the azimuth plane (H-plane), and a quasi-cosec/sup 2/ pattern in the elevation plane (E-plane).<>
