A high-selectivity microstrip wideband bandpass fllter with six transmission zeros using transversal signal-interaction concepts is proposed. A flfth-order wide passband with six transmission zeros (0{2f0, f0 is center frequency of the passband) can be realized two transmission paths. The bandwidth and locations of the transmission zeros can be adjusted conveniently by changing the characteristic impedances of open stub and coupling coe-cients of the open/shorted coupled lines. A prototype of planar wideband bandpass fllter with 3-dB fractional bandwidth 43.3% (2.33{3.63GHz) is designed and fabricated. The measured and simulated results both indicate good performances of high selectivity and wideband harmonic suppression.
