A Compact Power Divider Using Dual Composite Right-/Left-Handed Resonators (D-CRLH) with Filtering Response

A compact power divider using dual composite right-/left-handed resonators with good filtering response has been proposed for the first time in this paper. The power divider has a simple layout and can be designed by applying the theory of coupled resonators. A 1 GHz power divider with second-order Chebyshev response has been simulated and fabricated. The bandwidth of the power divider is 8%, and the in-band return loss is better than 15 dB. Consistent measured and simulated results are shown for validation.
