Transmitter Optimization for Mobile Wireless Power Transmission Applications

Abstract

In this study, a circularly polarized wireless power transmission (WPT) transmitter (antenna array) in the 5.8 GHz ISM frequency band is designed and optimized. An 8×8 phased array antenna is chosen to achieve high-power density and directivity. In this study, both the behavior of the unit element as well as the antenna array is studied and optimized. The analysis and optimization are performed based on the power density at 1 meter, 3 meters, and 5 meters over the practical range of elevation and azimuthal range of angles. the optimization process led to a proper RF power density at the receiver that can be used for some application works.
