Abstract
A high selectivity dual-wideband bandpass filter using a T-shaped structure based on transversal signal-interaction concepts is proposed. Several transmission zeros close to the two passbands can be achieved due to the superposition of signals for the two transmission paths. A planar dual-wideband bandpass filter prototype for GPS and WLAN bands with 3 dB fractional bandwidths of 28.8 and 22.7 has been designed and fabricated.
