摘要

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 second has the same amplitude as the sidelobe that must be suppressed and it presents a 180° phase shift. A one-dimension modulated surface reactance antenna is designed and sidelobe reductions of 14.5 dB and above 8 dB are shown in simulations and measurements, respectively.
