RADIATION PERFORMANCE OF HIGH EFFICIENCY DOUBLF REFLECTOR ANTENNA FED BY BEAM WAVEGUIDE

In this paper, the equations for calculation of the radiation performances on high efficiency double reflector antenna fed by beam waveguide are derived.Using these equations, the performance of the antenna can be predicted, such as the radiation patterns, the peak values of copolarization and depolarization, the factor of half power beam width, the phase loss and so on.These equations have been reformed to meet the requirements of general engineering eomputation. Some engineering computations are made, and some useful conclusions about the antenna are obtained.
