Abstract
In this paper, a compact and original feeding circuit architecture is proposed to synthesis the circular polarization of a triband antenna. A diplexer is used in this circuit in order to achieve circular polarization diversity, that is, right-hand circular polarization (RH-CP) for two radio-navigation bands (GPS/Galileo) and left-hand circular polarization (LH-CP) for a telemetry band (MicroSat TM). Simulation and measurement results are presented and validate the proposed feeding circuit concept.

Abstract
The development of a new passive wireless pressure sensor, based on the Electromagnetic transduction, is reported. The sensing element is a flexible high resistivity silicon membrane located above a coplanar resonator. The comprehensive coverage of the physical bases is beyond the scope of this paper. For the remote extraction of the applied pressure value, the passive pressure sensor is connected to a broadband horn antenna via a coaxial delay line. When interrogated by a Frequency Modulated Continuous Wave Radar, the level of the backscattered signal changes in response to applied pressure. The measured dynamic is about 0.8 dBm/Bar. This completely passive and wireless pressure telemetry micro-sensor has been designed, fabricated and characterized, thereby eliminating the need for contact, signal processing circuits, and power supplies to be contained within conventional sensors.

Abstract
Wireless sensors market is growing very fast these last years tanks to the availability of cheap, small and efficient micro-sensors, batteries, analog and RF circuits, and to the presence of standardized communication protocols. Even if these active sensors are very attractive for a lot of applications, they suffer from weak energy autonomy and they are not compatible with harsh environment. In order to overcome these problems, we have developed a new kind of wireless sensors using electromagnetic transducers and radar interrogation. These passive sensors (battery-less and without electronic components) have been studied for pressure, temperature and gas applications.
