Design of a Dual-Band Bandpass Filter Using an Open-Loop Resonator [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2017 In this paper, we present a novel design for a dual-band bandpass filter (BPF) based on the conventional second-order, open-loop BPF. By adding series resonant circuits to the open ends of the resonator, we can create two resonant modes from the even and
