Abstract The radiation field formulas are given for a parabolic torus reflector antenna. A five-beam parabolic torus antenna with 90?azimuth coverage has been designed and developed. An experimental radiation pattern of these five beams and theoretical patterns of the central beam of the antenna are also given. Comparison between calculated and measured patterns shows they are in good agreement. Finally, the measured gain data for the central beam and the edge beam are presented.
