ABSTRACT:
A microwave oven having an energy distribution system which produces efficient and uniform heating by utilizing a plurality of slotted feed apertures through which energy enters the top and bottom walls of the cooking chamber over a large area. A support shelf is provided for carrying an object to be heated and a rectangular waveguide is located immediately below the shelf which includes a first set of slots in its top wall to heat by use of near field effects and a second set of slots in its side walls which radiate energy toward reflecting surfaces in the bottom wall for further reflection upwardly into the chamber. A further set of feed apertures are located to pass energy into the chamber through the top wall thereof.
