Tem mode resonator

Abstract

A TEM mode resonator includes a tuneable cavity defined by an electrically conducting cavity wall. The cavity wall includes a grounding face, a capacitor face and a surrounding wall extending therebetween. An electrically conducting resonator member is disposed within the cavity and extends from the grounding face part way towards the capacitor face. A portion of the resonator member proximate to the capacitor face includes a recess defining an aperture. A tuning mechanism disposed outside the tuneable cavity, includes a tuning arm extending into the tuneable cavity through the aperture. The tuning mechanism is adapted to displace the tuning arm towards and away from the capacitor face. At least a portion of the tuning arm disposed within the cavity is the tuning element, which is formed of either a metal or a dielectric.
