ABSTRACT:
A quasi-lumped resonator apparatus that makes use of an inductive portion having a plurality of spines extending therefrom along at least a portion of a length thereof, and a capacitive portion electrically and physically coupled to an end of the inductive portion. The capacitive portion has a plurality of spaced apart capacitive fringe plates extending therefrom. A housing is included for enclosing the inductive and capacitive portions. In another aspect a method is disclosed for forming a quasi-lumped resonator.
