A Cassegrain Antenna with Additional Feeds for Partial Adaptive Channels

摘要

The choice of positions of additional feeds used to form partial channels ensuring adaptive reception in the near-lobe region of an antenna pattern is considered. An algorithm for calculating the characteristics of an antenna with additional feeds is presented. Examples are given of the choice of coordinates and dimensions of additional feeds that ensure specified characteristics of partial channels and do not cause characteristics of the main channel to deteriorate.
