Abstract :
Size reduction of microwave and millimeter-wave (mm-wave) resonator and filter incorporating a defective uniplanar compact photonic bandgap (UC-PBG) slow-wave structure is investigated in the standard 0.18-mum CMOS technology. Benefited from the multilayer mental technology of the standard 0.18-mum CMOS process, thin film microstrip structure is properly constructed on the lossy silicon substrate to reduce substrate loss. Defected periodic patterns on the ground plane are used to contribute to an enhancement of the effective dielectric constant and the slow-wave factor is 14% increased by the use of UC-PBG ground. Microwave and mm-wave passive circuits including resonator and filter are designed and fabricated. Measured results show that the use of UC-PBG ground has induced a frequency drop of 14% and validate the size reduction concept by using UC-PBG.
