ABSTRACT:
A supply wave guide system for microwave ovens consists of a wave guide of constant height and continuously varying width, which wave guide is terminated at the wider end by a short-circuiting wall. Microwave energy is fed into the wave guide at its smaller end. Microwave energy is fed from the waveguide into the oven cavity through at least two coupling apertures situated at the wider part of the wave guide and leading directly into the cavity, in which apertures stirrers, preferably movable and in the shape of rotating metallic wings, are situated.
