Outline of Final Research Achievements

In this research, novel rectennas suitable for microwave wireless power transmission to mobile devices are proposed and basic characteristics are discussed. The "both-sided MIC technology" is successfully employed in this rectennas to achieve useful functions for mobile devices with simple structure.
The rectennas are design and fabricated. The characteristic of the rectennas are investigated experimentally. It is confirmed that the proposed rectennas have a multi polarized wave reception function or a wide angle reception function. The proposed rectennas have good performances for mobile devices.
