Sidelobe Supression in Modulated Surface Reactance Antennas

Autor: Xavier Artiga

Publikováno v: 2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting.

This paper proposes a method for suppressing the sidelobe of a modulated surface antenna in a given direction. It is based on synthesizing two beams, one pointing at the desired direction, and the other at the interfering direction, so that this seco
