Abstract :
A novel triple-mode bandpass filter using an open-loop slotline resonator in a defected ground waveguide is presented. Distinct characteristics of the triple-mode resonator are investigated by using even-odd mode analysis. The proposed filter has been designed, fabricated and measured. Good agreement between simulation and measurement verifies the validity of this design methodology.
