Compact Dual-Mode Open Loop Microstrip Resonators and Filters [PDF]

IEEE Microwave and Wireless Components Letters, 2009
A novel compact microstrip dual-mode resonator and filter are proposed. The characteristics of the dual mode resonator are investigated. It is found that the filter response exhibits a desirable stopband response where the first spurious passband naturally occurs at 3f0. Finally, methods of miniaturizing such resonators and filters are discussed.

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
