A Novel Dual-Band Bandpass E-plane Filter Using Compact Resonators

This paper presents a novel dual-band bandpass waveguide E-plane filter using three pairs of resonators. In this configuration, two pairs of resonators are on the top of the substrate and the last pair is at the bottom. The length of proposed filter is less than 0.14 λ gL or 0.17 λ gH (λ gL and λ gH...

Description
Summary:This paper presents a novel dual-band bandpass waveguide E-plane filter using three pairs of resonators. In this configuration, two pairs of resonators are on the top of the substrate and the last pair is at the bottom. The length of proposed filter is less than 0.14 λ gL or 0.17 λ gH (λ gL and λ gH are standard waveguide wavelengths of the first and second passbands, respectively). Two passbands are designed flexibly with high selectivity and low insertion loss. A sample of the proposed dual-band filter is fabricated and tested. Good agreement between the simulation and measurement results is achieved. This kind of dual-band waveguide filter has benefits of low cost and mass production.
