Implementation of a compact microstrip power divider using novel split ring resonator

A compact planar wide-band power divider for microwave wireless applications is presented. The miniaturization of the compact broadband power divider is implemented by using a novel co-directional split ring resonator (SRR) structure. The SRRs are etched on the conduct signal strip, which can be easily fabricated and integrated in planer microwave circuits. The proposed power divider has a compact size of only 15 × 14.97 mm2. The measurement results show that the proposed power divider offers a wide bandwidth from 1 GHz to 7 GHz (S11 < −10 dB) successfully. The proposed power divider demonstrates equal dividing and good matching in all the relevant bands.
