FIELD: microwave engineering, possible use for thermal processing of food products.
SUBSTANCE: excitation of electromagnetic field in heating chamber is performed by means of line of two identical stripe antennas of circular polarization with emitter in form of circular metallic disk, enabled non-equidistantly. Line of aforementioned antennas is mounted inside the heat chamber on its side wall, and its longitudinal symmetry axis is parallel to lower wall and is at distance of 3/4 height of heating chamber from it. On external side of side wall of heating chamber, coaxial double T-bridge is mounted, providing for feeding of even values of microwave power from generator to stripe antennas.
EFFECT: increased efficiency of operation and evenness of energy distribution of microwave field inside the heating chamber.
