Abstract

In this paper, a single open ring resonator (ORR) filter with three resonants within its equivalent circuit has been investigated. This filter has a good response at ISM band from 3.13 GHz to 5.56 GHz. According to this filter, a concentric double open end ring resonator filter with an ultra wide band (UWB) behavior has been approached. The frequency response of this one is very appropriate up to 15 GHz. The loop of the filter constitutes both periodic self and mutual inductive-capacitive property between two rings which provides many resonants in these frequencies. The interconnections between these tanks are an important factor of its UWB behavior and they have overlap on each other impressively.
