A novel dual-band patch antenna based on metamaterial transmission line (TL) with zero refraction characteristic is proposed. The metamaterial TL proposed is constructed by a series capacitive gap between two metal patches combined with a complementary single Archimedean spiral resonator (CSASR) etched in the ground plane. The equivalent circuit model is applied to analyze the proposed antenna. The...
<?Pub Dtl?>Reduced-size single-feed circularly-polarized (CP) patch antennas are proposed and investigated based on the strategy of combining meta-surfaces and meta-resonators owning strong space-filling capability. They all comprise a slot-loaded square patch printed over a well designed reactive impedance surface (artificial meta-surface with magnetic response at the resonant frequency) for...
