Abstract

A new dual-band bandpass filter featuring flexible frequency choice is proposed.It consists of two resonators out of the two sides of the signal line with different sizes forming two passbands with desired frequency responses and bandwidths. For the resonator forming the lower passband, a shunt resistor is added at the center to make the even mode responses disappear. A wide stopband is obtained between the fundamental and higher odd mode response. So when a smaller resonator is put in the other side of signal line to produce the upper passband, a flexible frequency ratio of two passband can be gotten. The proposed filter is fabricated and measured. Good agreements are obtained between the simulations and measurements. Copyright © 2011 Wiley Periodicals, Inc.
