A Novel Compact Suspended Double Side CMRC Millimeter Bandpass Filter with Wide Stopband
By
Progress In Electromagnetics Research Letters, Vol. 21, 59-66, 2011
Abstract
This paper presents a novel compact suspended double side millimeter bandpass filter (BPF) with wide stopband using Suspended Compact Microstrip Resonant Cell (SCMRC). For SCMRC exhibit slow-wave band-stop characteristics, two distributed SCMRC structures are designed to achieve wide stopband characteristic. By apply SCMRC structure and double side design, this novel BPF is size reduced. Back-to-back rectangular waveguide to suspended microstrip probe transitions at different millimeter bands are designed and fabricated to verify transmission characteristics of novel SCMRC bandpass filter. Experimental results show low insertion loss (< 1.2 dB) in the passband and sharp, wide rejection in the stopband with about 150% bandwidth (below -15 dB, from 50 GHz to 100 GHz), make good agreement with simulated results.
