Abstract

This invention provides a microwave oven that is supplied with microwave energy through upper and lower feed openings in a side wall of the cavity. A wave guide is provided to feed those openings and is dimensioned to provide a resonance condition in the wave guide and a selected quality factor (Q-value) which is high in comparison with the Q-value of the oven cavity.
