Abstract

A 35GHz circular-polarized rectenna with high efficiency is proposed in this paper. The rectifier is designed at 35GHz using Schottky diode of MA4E1310. Two Schottky diode is series-parallel connected in the rectifying circuit, which has a measured rectifying efficiency of 54% with a 600 Ω when the received power is 63mW. The proposed rectifier is printed on the bottom side of antenna. The antenna is simulated by the full wave EM analysis software of HFSS and the rectifying circuit is simulated by using the ADS software. A four element rectenna array is designed with rotating array and the circular patch antenna fed by the coupling slot is employed to receive power form free space with a high gain of 12 dB. The low profile and easy integration of the proposed rectenna will be used for reference in the field of millimeter wave wireless energy transmission.(MMPT)
一种高效35 GHz旋转阵列圆极化整流天线
本文提出了一种高效率的35GHz圆极化整流天线。整流器采用MA4E1310肖特基二极管设计为35GHz。整流电路采用两个肖特基二极管串并联,当接收功率为63mW时,实测整流效率为54%,输出功率为600 Ω。所提出的整流器被印在天线的底部。采用HFSS全波电磁分析软件对天线进行仿真,采用ADS软件对整流电路进行仿真。设计了一种旋转阵列的四元整流天线阵列,采用耦合槽馈电的圆形贴片天线从自由空间接收功率,增益为12 dB。该天线外形小巧,易于集成,可为毫米波无线能量传输(MMPT)领域提供参考。
