Mathematical simulation of radiation for reflector-type antenna with a non-planar edge

The calculation method for reflector-type antenna with an edge representing a non-planar space curve is considered. Central to the theory is an implementation of scattered field integral representations obtained with the help of Lorentz´ lemma. The contribution from reflector edge sections to a total antenna field is carried out with the usage of the model problem for electromagnetic scattering by a wedge. By way of illustration near-field and far-field radiation patterns of an antenna with a reflector as an elliptic cutting-out from a paraboloid of revolution are presented.
