Patent ID: 8398303

Claim:
A temperature measuring probe comprising: a hollow outer shell including an electrically conductive section and an electrically insulating section; a temperature sensor disposed in the electrically conductive section and electrically conductively connected to the electrically conductive section, the temperature sensor including a resonator; and an antenna disposed in the electrically insulating section, the antenna including a shortened monopole; wherein the temperature sensor and the antenna are electrically conductively connected to each other, a top load capacitance being formed between a tip of the antenna and the electrically conductive section of the outer shell, the tip of the antenna and the electrically conductive section forming electrodes of the top load capacitance and the insulating section forming the dielectric of the top load capacitance, and wherein a respective material and respective dimension of the electrically insulating section and the antenna are matched based at least in part on the top load capacitance such that an effective resistance of the antenna is approximately equal to an effective resistance of the temperature sensor in an operating frequency range of the temperature sensor so as to provide impedance matching.
