Abstract
In this paper, a near-field coupled transmitting-receiving antenna pair is proposed to achieve the maximum transmission efficiency. The antenna structure developed can achieve up to 77 % transmission efficiency in near-field coupling region. Additionally, through the rectifier circuit design, the front-end antenna pair will convert the radio frequency energy received into DC output. The maximum conversion efficiency of the proposed receiving rectenna is about 80% at the incident power level of 24 dBm and the load impedance of 1 kΩ. The output DC voltage of the rectenna is 13.12 V as the maximum conversion efficiency occurred.
