A novel hairpin resonator incorporating a defective uniplanar compact photonic bandgap (D-UCPBG) slow-wave structure has been developed using monolithic silicon-based CMOS technology and the impact of the D-UCPBG slow wave feature on the hairpin resonator performance is presented. Two stepped impedance hairpin resonators of equal dimensions, one with a solid ground plane and another with a D-UCPBG structure, were implemented in the TSMC 0.25 m RF-mixed signal fabrication process. The D-UCPBG incorporated hairpin resonator resonates at 4.5 GHz, a significant frequency reduction from 10.2 GHz, the resonant frequency of the solid ground plane based hairpin resonator. The loaded Q of the resonator also increases from 5.8 for the solid ground plane resonator to 13 for the D-UCPBG structure. 2005 IEEE.
