Abstract
A novel 3 dB power divider based on dual-composite right/left handed transmission line (D-CRLH TL) is proposed for the first time. The D-CRLH TLs are applied as artificial transmission lines. The wideband compact D-CRLH power divider is with low insertion loss and excellent amplitude and phase balance. The experimental results show that |S 11| is below −15 dB; the isolation is higher than 15 dB; and the insertion loss is less than 1 dB from 0.85 GHz to 4.3 GHz. The two output ports achieve the same amplitude and phase. The amplitude balance is below 0.3 dB, and the phase balance is less than 3°. The simulation results agree well with the measurements. The power divider has good application prospects in microwave systems.
