Outline of Final Research Achievements |
Both broad-side and end-fire array antennas that can be mounted into a frame of eye glasses and finger-wearable ultra-wideband ring-type antennas have been proposed and investigated. Also, the radiation efficiencies of embroidered wideband dipole and slot antennas have been assessed with measurements including the effects of the human body using human equivalent phantoms. In order to improve the quality of body centric wireless communications, a polarization diversity antenna has been designed for Bluetooth wearable wireless devices. A 10 dB gain has been archived by using the polarization diversity technology and has been confirmed by experiments. Besides, a novel position-based routing protocol using directional antennas and a novel multicast forwarding scheme for mobile ad-hoc networks have been proposed and the effectiveness of the proposed approaches has been confirmed through both computer simulations and experiments using real wireless mobile devices.
