The proposed resonator is directly connected to Input/Output (I/O) ports to obtain a wide stopband and loading elements are also employed to control the zeros and poles. The transmission-line model is used to explain the design methodology clearly. Simulated and measured responses show an excellent agreement.eninfo:eu-repo/semantics/closedAccessConference Object2-s2.0-85021219797N/AWOS:000405560500170N/A
