This paper proposes a new process of temperature measurement of a material or object at microwave frequencies. This process allows self-balancing of the temperature measurement system and takes into account any mismatching between the antenna and the radiating object. The process uses a temperature sensor based on a monolithic integrated circuit. A theoretical and experimental study is conducted to test this process.
