Oven antenna probe for distributing energy in microwave

Abstract

Antenna for use with food product in a microwave oven, where one or more antennas are positioned into the food product for efficient and distributed heating of food product. The antenna includes a coaxial assembly of an inner conductor and an outer conductor with dielectric therebetween. A load end, configured as a probe, positions into the food product. A source end antenna element structure delivers power to the load end and subsequently to the food product. The structure at the source end may include a probe center conductor as well as gain antenna structures. The outer conductor may likewise be configured including ground plane disc, a folded-over coaxial outer conductor or the like.
