Abstract :
The method for calculation of a radiated field of a reflector antenna which edge represents a non-planar space curve is considered. The method is based on the application of integral representations of fields scattered by the reflector that were obtained with the help of a Lorentz lemma. The calculation of reflector edge sections field contribution to a complete antenna field is carried out with the help of a solution of the problem about scattering of a plane electromagnetic wave on a wedge. The results of calculation of an antenna fields with a reflector as an elliptic cutting-out from a paraboloid of revolution are given.
