This study demonstrates an efficient 5.8 GHz microwave wireless power transmission (MWPT) system. The whole system comprises a transmitting subsystem and a receiving subsystem. A 64-way phased microwave power source and a transmitting antenna array of 1 m Â 1 m are included in the transmitting subsystem. By exciting the transmitting array with a 10-dB Gaussian amplitude distribution and a quadratic phase distribution via the phased microwave power source, the transmitting subsystem radiates a low side-lobe and focused microwave beam. The receiving subsystem comprises a receiving antenna array of 0.5 m Â 0.5 m and 64 rectifiers. The efficient receiving antenna array and rectifiers realize an efficient rectenna array. An experiment on the MWPT system is conducted. The total microwave power output from the source is 24 W, and the transmission distance is 10 m. According to the measurements, the total rectified direct current (DC) power is 4.58 W, and the overall RF-DC efficiency is 19.08%.

Dielectric Metasurface Inspired Directional Multi-Port Luneburg Lens as a Medium for 5G Wireless Power Transfer—A Design Methodology

et al. 2022

View full text Add to dashboard Cite

In this paper, a novel dielectric metasurface-inspired multi-beam directional Luneburg lens is proposed as a wireless power transfer medium at 5G mm-wave band. The lens is constructed using dielectric-based unit cells made up of a glide symmetric approach. It is connected with a set of microwave detector integrated multi-port tapered rectangular feeds to convert the received RF energy from different directions to DC power across a combined load. The proposed structure can be a potential candidate to harvest ambient energy from a wide coverage range of around 160°and produce a power conversion efficiency of about 76% for an input power of 14.9 dBm at 24 GHz.
