MINIATURIZED AND HARMONIC-SUPPRESSED RF WILKINSON POWER DIVIDER WITH IB-CMRC

Abstract

In this paper, the technique served by a microstrip electromagnetic band gap cell entitled IBCMRC is employed to suppress the high-order harmonics and reduce the length by over 30% for a quarter-wave conventional transmission line. The successful application of IB-CMRC cell in a 2 GHz Wilkinson power divider shows that the second and third harmonics are successfully suppressed without downgrading the performance at the operating frequency. The whole size of the proposed IBCMRC-based divider has been reduced by 42% compared to the conventional divider. In miniaturization and harmonic rejection of microwave circuits, the proposed IBCMRC technique holds great promise.
