A Space Millimeter Wave Wireless Energy Transmission System

Abstract

The traditional microwave power transmission is based on S-band and C-band microwave, and its frequency is generally lower than 8 GHz. Therefore, the power transmission system is bulky. In this paper, a space millimeter wave wireless energy transmission system is proposed, which uses Ka band millimeter wave for wireless energy transmission. Compared with the traditional microwave power transmission system, the frequency is up to 35GHz. The antenna array has the advantages of small volume, long transmission distance and high aspect ratio energy transmission.
