60-GHz-band low-loss on-chip band pass filter with patterned ground shields for millimeter wave CMOS SoC

Summary form only given, as follows. This paper presents a design of an improved on-chip open-loop-resonator band pass filter (OLR-BPF) for 60 GHz applications in 0.18 µm CMOS technology. The proposed BPF employs the folded open loop structure on patterned ground shields. By comparison, the proposed BPF has the center frequency of 59 GHz, insertion loss 2.77 dB, band width 14 GHz, return loss less than 27.5 dB, and chip size 910×650 µm².
