The authors describe an antenna for the 3-cm band in the form of a radial waveguide which passes into a biconical horn and is excited at the center by a circular waveguide which is matched to the radial waveguide by three cylinders coaxial with it. The radiation pattern is controlled by means of an electrically controllable polarizer which consists of two ferrite rotators of the polarization plane separated by a 14-wave plate of polystyrene, and a matched converter.
