Abstract :
A dual-wideband bandstop filter with high selectivity using transversal signal-interaction concept is proposed. Five transmission poles in the passband between the two stopbands can be achieved due to the superposition of signals for the two transmission paths. A planar dual-wideband bandstop filter prototype for WLAN bands with 10 dB fractional bandwidths of 76.2% and 26.9% has been designed and fabricated.
