A Novel Method of Beam Compression Based on Artificial Magnetic Conductor

Abstract

In this manuscript, a novel method of beam compression is proposed, which is based on artificial magnetic conductor. The artificial magnetic conductor consists of an array of split ring resonators. Located at the front of an antenna element, the array can compress the radiated beam by the magnetic resonance. Validated by simulation, the beamwidth can be compressed by 15% and the radiated gain can be increased by 0.5 dB.
