Comprehensive mathematical analysis and simulation design of a microwave wireless power transmission system

Abstract

Wireless power transmission, an idea first proposed and demonstrated by Nikola tesla in the beginning of the 20th century has seen immense improvement up until date, with the latest developments in the field including wireless charging of electronics having already graced the consumer market. In this paper, tremendous focus is put into improving the efficiency of the system, notably, the antennae efficiency, specific waveforms used to in transmission to achieve optimal efficiency. First, the non-uniform antenna array is designed and discussed. Additionally, mathematical analysis and software simulation designs of rectenna division, specifically, the rectifier part were performed. Consequently, a special type of rectifier known as the class F rectifier is discussed in detail simulated with different diode models to show the different improvements in the efficiency of the system depending on the type of diode used. Four waveforms were also compared, and simulation results given and compared to experimental results done in earlier work.
