Patent Images
1. An oven appliance, comprising:
- a cabinet defining an oven cavity;
a heat source disposed within the oven cavity; and
an antenna device mounted to the cabinet, the antenna device comprising;
an outer sheath defining an interior volume and formed of a conducting material, the outer sheath extending between a first end and a second end and forming a predetermined tuned length, the first end extending into the oven cavity;
a temperature sensor disposed within the interior volume of the outer sheath and positioned within the oven cavity, wherein the temperature sensor is electrically isolated from the outer sheath;
a ground cylinder disposed about the outer sheath; and
a dielectric sleeve disposed between the outer sheath and the ground cylinder, wherein the outer sheath is electrically isolated from the ground cylinder by the dielectric sleeve.
