[Invited Lecture] A Design and Experiment of Dual-Frequency Directional Rectenna

Abstract (in Japanese) (See Japanese page) 
(in English) In a wireless power transmission system using microwaves, it is important to improve the efficiency of a rectenna (Rectifying Antenna) consisted of an antenna and a rectifier circuit. The rectenna receives the electromagnetic energy of the space by the antenna and outputs the DC electricity by the rectifier circuit. Therefore, they are important to increase the gain and the efficiency of the antenna and increase the efficiency of the rectifier circuit. Also, by transmitting over a wide band or at multiple frequencies, it becomes possible to transmit power with higher power, but devises are required to optimize the antenna and the matching circuit for each frequency. In this research, a rectenna having directivity in the same direction at two different frequencies was designed.
