Efficient Energy Transport in 60 Ghz for Wireless Industrial Sensor Networks

Radio frequency energy transport is a viable technology to power small-sized sensors in wireless industrial sensor networks (WISNs). 60 GHz wireless communication emerges as one of the leading technologies for next generation wireless networks, and it can also be useful to build up WISNs. In this article, we investigate the efficiency of RF energy transport in WISNs with 60 GHz communications. We present a spherical antenna design with supported analytics on directional antennas in 60 GHz wireless communications. We introduce and solve the spherical distribution problem of directional antennas to maximize the energy transport efficiency in WISNs. The extensive simulations given in this article verify that the proposed antenna configuration performs much better than the existing solutions in WISN applications.
