摘要

An improved structure of rectangular waveguide band-pass filter with harmonic suppression is proposed. The filter consists of cascade resonant cavities with coupling provided by irises. By means of varying the width of each resonator and the offsets between the adjacent resonant cavities, the stop-band was successfully pushed to a two octaves frequency range. The results show that the designed rectangular waveguide band-pass filter has a pass-band of 27.5 GHz – 30 GHz and stop-band suppression of greater than 33 dB over the frequency range from 35 GHz to 60 GHz, its pass-band insertion loss is less than 0.1 dB, return loss is more than 19 dB. The filter can be used in modern communication systems with the requirement of harmonic suppression.
