Microwave Power Transmission Using Electromagnetic Coupling of Open- Ring Resonators.

摘要

Experimental results on 60GHz band signal transmission through ECOR (Electromagnetic Coupling of Open-Ring Resonators) are shown. Through sapphire substrate, 60-70GHz band signal are transmitted with 58.9% transmission efficiency and 7.4GHz bandwidth. However, the transmission band was shifted about 10GHz higher frequency. The reason is under investigation. ECOR technology is extended to lower frequencies for non-contact power transmission. The technology will benefit to power connectors for equipment modules where the problems caused by humidity and mechanical failure will be eliminated. A new diode structure for RF signal rectification, loss mechanism in rectenna circuits and the effect of wetting to ECOR transmission will be presented.
