Abstract


A compact four-band Asymmetric bi-Layer circular polarizer is presented based onH-shape split ring resonator. The proposed structure exhibits the four-band asymmetric transmission (AT) of circular polarization with low loss transmission. Compact four-band Asymmetric bi-layer circular polarizer converts impinged x-polarized wave to obtain left-handed circular polarized (LHCP) waves at 32.80 GHz and 37.52 GHz and right-handed circular polarized (LHCP) waves at 34.40 GHz and 39.50 GHz. The proposed structure rigorously satisfies the AT and realizes the cross-polarization conversion with high efficiencies at distinct resonant frequency bands.
