Antenna Radome Using Split Ring Resonator

摘要

In this paper, application of coupled square shaped split ring resonators (CSSSRR) is extended to enhance gain of a circularly polarized (CP) microstrip patch antenna. We etch coupled CSSSRR on both sides of a superstrate which is separated from the patch by an air layer. Open gaps of each CSSSRR on opposite side of the superstrate are orthogonally oriented to each other. This unique orientation allows the radome not only enhance gain but also maintain good CP performance for the patch antenna.
