Abstract :
A novel fifth-order wideband bandpass filter using open/shorted coupled lines is proposed. A wideband passband with eight transmission zeros from 0 GHz to 2f0 (f0 is centre frequency of the passband) can be achieved respectively due to the superposition of signals of the two transmission paths. A wideband bandpass filter prototype with 3-dB fractional bandwidth of 62% (2.12-3.98 GHz) is designed and fabricated.
