IMPROVED ROTATING SLOT ANTENNA ARRANGEMENT FOR MICROWAVE OVEN ABSTRACT An improved excitation system for a microwave oven employing a circulating rotating disk antenna configured to radiate peripherally from its outermost edge to provide background radiation in the oven cavity. Primary microwave energy radiation is emitted from a pair of transverse radiating slots formed in the disk antenna. A first slot is positioned radially outwardly relative to the second slot. The first slot alternately functions as a relatively strongly coupled series and shunt radiating slot and the second slot concurrently alternately functions as a moderately coupled shunt and series slot with each quarter revolution of the disk antenna. Both slots are louvered for improved coupling to the load being heated in the cavity.
