Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A device for receiving, transmitting and re-radiating microwave energy from the cavity of a microwave oven into the interior of a food body positioned therein, comprising: a rigid coaxial transmission line having an inner conductor and an outer conductor having first and second ends; a radiating antenna comprising a probe of said inner conductor extending beyond said first end of said outer conductor, said radiating antenna probe being encased in a dielectric material having a point for inserting said radiating antenna into said food body; and a receiving antenna comprising a probe of said inner conductor extending beyond said second end of said outer conductor and a ground plane defined by a disk connected perpendicularly to said second end of said outer conductor wherein a portion of said microwave energy radiated into said cavity is received by said receiving antenna, is transmitted along said rigid coaxial transmission line, and is re-radiated from said radiating antenna to the interior of said food body.
Claim 2
Independent Claim
162 words
A device for receiving, transmitting and re-radiating microwave energy from the cavity of a microwave oven into the interior of a food body positioned therein, comprising: a rigid coaxial transmission line having an inner conductor and an outer conductor having first and second ends; a radiating antenna comprising a probe of said inner conductor extending beyond said first end of said outer conductor, said radiating antenna probe being encased in a dielectric material having a point for inserting said radiating antenna into said food body; and a receiving antenna comprising a probe of said inner conductor extending beyond said second end of said outer conductor and a ground plane defined by a disk connected perpendicularly to said second end of said outer conductor wherein a portion of said microwave energy radiated into said cavity is received by said receiving antenna, is transmitted along said rigid coaxial transmission line, and is re-radiated from said radiating antenna to the interior of said food body.
Claim 3
Dependent Claim
12 words
