Microwave radiating applicator with reduced sensitivity to surrounding media

摘要

A microwave energy applicator radiating uniformly all around the applicator that maintains high efficiency Voltage Standing Wave Ratio (V.S.W.R.) for surrounding media of dielectric constants varying from about 1 to about 80. In a particular embodiment, the high efficiency V.S.W.R. is less than about 1.3:1. The applicator can include a circular polarizer connectable to a dielectric waveguide radiator. The radiator can be substantially solid and include a substantially circular outer cross-section that tapers to an end. In one embodiment, the radiator includes a conical void formed in a dielectric entry section.
