Compact multiband bandpass filters based on parallel coupled split structure multimode resonators
Abstract In this letter, a novel sext‐band bandpass filter (BPF) using two split‐type multiple‐mode resonators is proposed. The filter is composed of two sets of resonators which are respectively designed to realize Filter 1 with two passbands and Filter 2 with quad passbands. Then the two BPFs are...

| description | Abstract In this letter, a novel sext‐band bandpass filter (BPF) using two split‐type multiple‐mode resonators is proposed. The filter is composed of two sets of resonators which are respectively designed to realize Filter 1 with two passbands and Filter 2 with quad passbands. Then the two BPFs are combined by parallel coupling feed lines for sext‐band responses, and each of the six centre frequencies in the proposed sext‐band BPF is able to be controlled due to the design freedom. To validate the design and analysis, a prototype filter has been fabricated with six passbands centred at 1.88/2.59/3.48/5.26/5.82/6.75 GHz. The measured result of the fabricated filter agrees well with the simulation, which shows that the proposed structure is a good candidate for sext‐band BPF designs and validates the proposed design flow well. |
