Energy coverage analysis of millimeter wave wireless power transfer

Abstract

The millimeter wave (MMW) region received great interest in wireless communication applications as it provides large bandwidth ranging from 30 GHz to 300 GHz. MMW communication is a new feature of fifth-generation (5G) and beyond 5G cellular networks. The large antenna arrays that will be implemented in the MMW system potentially increase user performance. Since the MMW system performance closely depends on the antenna gain, a suitable antenna pattern model is crucial to predict the MMW system performance before the real base station implementation. This paper presents a simplified antenna model known as a modified sectored (M-sectored) antenna that incorporates the number of antenna elements. Leveraging the concept of stochastic geometry, this paper analyze the energy coverage probability of MMW wireless power transfer. The locations of base station and users are modeled following Poisson point processes (PPP), and then the effect of the antenna model is investigated. This study had demonstrated that the energy coverage probability (ECP) of the proposed antenna model matches the actual antenna gain pattern. In addition, the effects of the base station density and blockage parameter are also observed.
