Dual-mode dual-band microstrip filters
2009 European Microwave Conference (EuMC), 2009 A compact dual-band microstrip bandpass filter is proposed using dual-mode resonators. Two microstrip loop resonators, one within the other, are employed to obtain dual-mode dual-band filter responses. Each loop resonator uses two loading elements to excite dual modes.
