| Overview |
|
The work follows two main directions in the important field of near-body antennas: antennas for body-area networks and antennas and techniques for medical microwave imaging. In both cases the emphasis is put on the development of very simples and inexpensive antenna solutions, yet with remarkable performance for the intended functions. For the first topic, the new developments include both implanted antennas for implanted sensors, and on-body antennas (including stick-on antennas) that can operate not only with near-body sensors, but also as relays between implanted antennas and off-body access points. Regarding microwave medical imaging, our studies show that other antenna design requirements need to be addressed further to the usual UWB figures of merit, in order to obtain the best possible image inversion results. We discuss these characteristics and present antennas that match those additional requirements. We also focus on full system demonstrators to evaluate the antenna impact on system performance.
