MICROWAVE SENSORS

The purpose of this paper is to present some of the microwave sensors developed at the Institut d'Electronique et de Microelectronique du No rd, that can address a wide variety of applications in the fields of d omotic, automotive, robotic communication and hyperthermia. The recent emergence of Microwave Monolithic Circuits MMIC's together with the d evelopment of collective microtechnologies and quasi-optical technique s enable the design of low cost microwave sensors that can detect refl ected or transmitted electromagnetic waves from a microwave source or microwave emitted by black bodies. These unique features of microwaves have been advantageously used to realize microwave automatic cooking process control, radar and communication front ends, accurate robot lo calization systems and biomedical applicators that are briefly describ ed in the paper.
