Abstract

A microwave oven having a low friction bearing support for a rotatable microwave feed assembly which includes a primary radiating antenna axially coupled to a cylindrical metal stub that vertically extends from the microwave cavity through an aperture into the waveguide where it is excited by microwave energy. The stub has a bottom cylindrical bore which inserts over a microwave transparent post that extends upwardly through the aperture from a horizontal cross bar suspended by two legs connected to the cavity ceiling. The cross bar may be oblique to the waveguide to centrally and positively align the post in the aperture. The roof of the bore has a downward spherical surface which provides a low friction bearing with the microwave post. The feed assembly also includes a microwave transparent turbine against which a stream of air is directed to rotate the feed assembly.
