—This paper proposes a novel, low-profile UWB antenna for wireless body area network (WBAN) applications. The antenna has a polarization perpendicular to the body-free-space interface, which is interesting in order to minimize the coupling into the body. Its structure comprises a modified mono-cone with a top-cross-plate and is coaxially fed through the(More)
—The design procedure, realization and measurements of an implantable radiator for telemetry applications are presented. First, free space analysis allows the choice of the antenna typology with reduced computation time. Subsequently the antenna, inserted in a body phantom, is designed to take into account all the necessary electronic components, power(More)
In this paper a new wireless sensor node intended for use in ultra-low power Wireless Sensor Networks (WSN) is presented. The node uses commercial of-the-shelf radio, microcontroller and a custom developed antenna embedded in the housing. Over-molding with food-compatible material is used to improve the mechanical robustness of the node. The present work is(More)
—In this paper a 30 GHz multi-beam antenna prototype has been developed for High Altitude Platform Stations (HAPS) applications. When mounted on a HAPS at the stationary altitude of 21Km, this antenna provides cellular coverage on the ground. The antenna consists of a dielectric lens fed by circular waveguides terminated with small horns. Circular(More)

The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a wide range of frequencies up to millimeter waves for various applications, such as field mapping of(More)
In vapor cell atomic clocks the atom-field interaction is typically obtained inside a microwave cavity resonator in which the microwave driving field together with a static magnetic field and an optical field are applied to excite the atoms. These fields are generally well-controlled, mutually aligned to a common quantization axis. Since the exploited(More)
