Large and Simple Phased Array System at 28 GHz for Beam Wireless Power Transfer

Space-based solar power (SBSP) is envisioned as a future CO2-free power station in space. One of the critical technologies for SBSP is beam wireless power transfer (WPT). In this paper, we present the development of a new large and straightforward phased array system operating at 28GHz, designed for simultaneous wireless information and power transfer (SWIPT). We believe that SWIPT is a crucial step toward realizing SBSP. This paper introduces the developed phased array, focusing on its applications in SWIPT as a business system and its potential as the primary technology for SBSP, the largest anticipated application of WPT.
