Abstract

The purpose of this paper is to present various equivalent circuits of the coupled square-loop resonator which can be used for realization of narrow bandstop filters like notch filters. Furthermore, it is made clear that those circuits vary by the relation of characteristic impedances of component lines in the resonator.
