## Abstract In this article, a novel type of dualβband bandpass filter (DBBPF) is proposed by using microstrip composite resonators, and its design method is developed based on the lumpedβelement equivalent circuit of the filter. Both the midband frequencies and the passband widths of the dual band
## Abstract A compact microstrip dualβband bandpass filter (DBBPF) with controllable bandwidth for each passband is proposed. Each passband is independently designed using two different dualβmode resonators. The proposed DBBPF has three transmission zeros. Two transmission zeros are generated by ea
