Abstract
A microwave apparatus includes a coaxial feed connected to a microwave waveguide and extended into a rotating antenna applicator in a microwave cavity, wherein a gap between the ceiling of the microwave cavity and the top of the rotating antenna applicator as well as between the coaxial feed and the rotating antenna applicator is present to facilitate the rotation of the antenna applicator. The presence of these gaps permit radial leakage, uncontrolled excitation of modes and occasional arcing. An annular knob is provided proximate the coaxial feed and attached to the top of the rotating antenna applicator to suppress radial leakage, uncontrolled excitations and arcing in the microwave cavity.
