Abstract

A microwave resonator is formed by a cylindrical conductive loop and one or more gaps which extend along its length. The loop forms an inductive element and the gaps form capacitive elements which determine the resonant frequency. The loop is surrounded by a conductive shield which improves the quality factor (Q) of the resonator and high frequency radio signals are coupled to the resonator by an inductive loop positioned at one of its ends.
