Abstract

This paper presents a compact, dual-polarized rectenna array operating at 2.45 GHz and demonstrates its use in a microwave wireless power transmission (MWPT) system. The MWPT system comprises a compact voltage-controlled oscillator (VCO), a power amplifier (PA), and the dual-polarized rectenna array. The VCO and PA together form a transmitter that delivers an output power of 1 W at 2.45 GHz. The transmitter’s DC power port features a universal type-C interface, which facilitates its use in daily life. We designed a meander-line dipole rectenna that eliminates the matching network between the antenna and diode. The meander-line structure improves the rectenna’s impedance and reduces its size. The measured maximum efficiency of the rectenna is 62.5% at −2 dBm. DC power combining is applied to the rectenna array to achieve dual polarization and voltage boosting simultaneously. The proposed rectenna array is integrated into a commercial digital thermometer. The digital thermometer was powered by the proposed MWPT system, demonstrating its bright prospects for MWPT applications.

S波段紧凑型弯折线双极化矩形天线阵列设计及应用演示

本文提出了一种在2.45下工作的紧凑型双极化矩形天线阵列并展示了它在微波无线功率传输（MWPT）系统中的应用。MWPT系统包括一个紧凑型压控振荡器（VCO）、一个功率放大器（PA）和双极化矩形天线阵列。VCO和PA一起形成一个发射机，输出功率为1 W，2.45 GHz。变送器的直流电源端口具有通用的C型接口，便于在日常生活中使用。我们设计了一种曲折线偶极天线，消除了天线和二极管之间的匹配网络。曲折线结构提高了矩形天线的阻抗并减小了其尺寸。在−2时，测得的矩形天线的最大效率为62.5% dBm。将直流功率组合应用于矩形天线阵列，以同时实现双极化和升压。所提出的矩形天线阵列被集成到商业数字温度计中。数字温度计由所提出的MWPT系统提供动力，显示了其在MWPT应用中的光明前景。
