ABSTRACT:
A rotating antenna is provided for use in a microwave oven having drive apparatus for rotating the antenna, a heating cavity, a source of microwave energy and a waveguide between the heating cavity and the source of microwave energy. A probe extends into the waveguide for coupling with the microwave energy and is connected to a center-fed dipole radiator in the heating cavity. Radiation modifying elements are integral with the dipole radiator to provide increased radiation in the central portion of the heating cavity. Impedance balancing elements are also integral with the dipole radiator and cooperate with the probe to effectively match the impedance of the source of microwave energy with the impedance of the heating cavity to permit substantially full microwave power to be delivered to a cooking load.
