Abstract
In this paper, a suspended-rectangular patch rectifying antenna (rectenna) array for 2.45 GHz wireless power transmission is presented. The proposed rectenna, which consists of an antenna array and a rectifying circuit, is designed to convert the RF signal into DC power. The antenna structure is designed by using a rectangular patch which radiates unidirectional pattern. The air substrate of the antenna is used to achieve high gain. The rectifying circuit is designed based on voltage diode with stub matching circuit. The dimension of the proposed antenna is square of 190 mm. The measured gain of this antenna is 14 dBi. At the distance of 1 m, the proposed rectifying circuit achieves the output voltage of 1.5 V and output current of 0.15 mA with a 1 MΩ resistor load and a transmitter power of 34.6 dBm EIRP.
