Abstract :
A design of a 2-pole bandpass filter (BPF) with multiple attenuation poles is performed. In this study, the multiple attenuation poles are realized by using the combination technique of two different tapped resonators. Miniaturization of the BPF with multiple attenuation poles is also realized on the basis of the loaded-element resonators (LERs). It is confirmed that our proposal is of great use for creating multiple attenuation poles by the few number of the resonators
