Novel Yagi-Uda antennas for on-body communication at 60GHz

On-body communication is of increasing interest for a number of applications, such as medical-sensor networks, emergency-service workers, and personal communications. This paper reviews 60 GHz on-body communication and its benefits and challenges. Two novel low profile high gain, end-fire wearable antennas are then described. They are promising candidates for on-body channels at 60 GHz. The first one is a conventional printed Yagi array, which gives up to 17 dB gain and 6 GHz bandwidth. The other is a substrate integrated waveguide Yagi antenna which also gives 15 dB gain. Because these two antennas have different polarization, they can be used to investigate 60 GHz on-body channels in future work.
