Abstract :
Two simple mathematical models are described for the prediction of the vector radiation fields from offset parabolic reflector antennas with offset feeds. Experimental support for the predictions obtained from the models has been obtained by comparisons with measured data from antenna systems operating at 30 GHz. The principal radiation characteristics of the offset-reflector with offset-feed configuration are discussed.
