| Outline of Final Research Achievements |
In this study, a novel rectenna is proposed and basic characteristics are investigated. This study can improve the wireless power transfer system. Antenna elements are integrated with a rectifying circuit to form a rectenna that has a differential operation with a compact structure. This rectenna has two significant advantages that are an expandability and a high RF-DC conversion efficiency.
A DC-array and RF-array using the proposed differential rectenna as an array unit achieving a high power output are proposed. Because of the compact structure of the differential rectenna, a large scale rectenna that consists of many antenna elements can be design in a simple procedure. In addition, the rectenna is modified to improve the RF-DC conversion efficiency and to achieve any polarization receivable function.
It is conferred that the proposed rectennas and the arrays has excellent performances.
