To reduce the weight of a satellite, an internal wireless system (IWS) for satellites was proposed in a previous study. It is a system that can communicate between the satellite’s subsystems by using wireless communication modules. In this paper, we propose a complete IWS for a satellite using microwave wireless power transmission technology. The design of a 5.8-GHz high efficiency rectifier circuit-based...

Open-ring resonator coupling is used for the wireless power transmission through 1.6mm thick epoxy-glass plate. Microwave signal is emitted from one circuit board where an open-ring resonator is placed and the signal is received by another board with also an open-ring resonator and GaN Schottky barrier diode. At 2.3 GHz, RF to DC conversion efficiency of 37.1 % is obtained at the input power of 3...
This paper presents the 5.8 GHz high sensitivity rectenna array with advanced microstrip-type rectifiers and circularly patch antennas achieving a good balance between a high-efficiency and RF weak power operation. The fabricated rectenna element has achieved RF-DC conversion efficiency of 54% at input RF power of 1mW. Furthermore, we have proposed the novel structure which enhances robustness to...
