—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)
—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)
—This work presents the analysis of the influence of insulation on implanted antennas for biotelemetry applications in the Medical Device Radiocommunications Service band. Our goal is finding the insulation properties that facilitate power transmission, thus enhancing the communication between the implanted antenna and an external receiver. For this(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)
