A Linearly Polarized Rectenna for Far-Field Wireless Power Transfer

Abstract

A rectenna, which consist of a yagi Microstrip antenna along with rectifier circuit is proposed for wireless power transmission in the far field region. The wireless power link is examined between an insitable antenna and an external antenna. A method of adding directors in yagi antenna is used to increase the wireless power link, thus to enhance the efficiency of the designed antenna. After calculating an receiver power level of an insitable antenna, the rectifier circuit efficiency is optimized. Yagi uda antenna is operated at a frequency of 2.4GHz to 2.485GHz.
