Abstract : The radiation problems of microwave horn antennas which are circularly symmetric (bodies of revolution) can be analyzed by the method of moments. With this approach, the induced currents on the horn surface can be decomposed into longitudinal and azimuthal components. Each current component is expanded in series form with piece wise sinusoidal basis functions and the amplitude of each current sample is solved. From the resulting surface currents, the radiation patterns of the horn are calculated. This report summarizes this method and compares the calculated patterns with measured patterns for several horn antennas, including conical horns, corrugated horns and dual mode horns.
