Compact Dual Band Ring Coupler Using Miniaturized Metamaterial Left-Handed Impedance Inverters
A compact 3-dB dual band ring coupler is designed, fabricated and tested. The coupler consists of three identical miniaturized Left-Handed (LH) impedance inverter transmission lines (TLs) and a dual one. The general principle of using LH TLs’ duality to reduce the size of a dual band ring...
