摘要:
为了提升微波无线能量传输(MPT)的传输效率,提高接收功率,研究了一种基于旋转矢量法(REV)的天线阵相位快速优化法。结合相控阵和微波无线能量传输的基本理论,对该方法的优化效果进行了电磁仿真分析和实验验证。结果表明,在辐射近场区和远场区内,该方法能有效提高微波无线能量传输的接收功率,提升率最高达179%。同时,该方法可大幅度缩短相位优化时间,仅为传统方法耗时的3%,由此证明了该方法在MPT工程中的可行性。
Abstract:
A fast phase optimization method based on rotating element electric field vector (REV) for antenna array is presented to increase the transmission efficiency and the receiving power in a microwave power transmission (MPT) system. The proposed method is analyzed by electromagnetic simulation and verified through experiments on the basis of phased-array and MPT theory. It shows that in both Fresnel region and far field region, the proposed method can enhance receiving power of MPT effectively, and the maximum power improvement ratio reaches 179% at most. Additionally, the proposed method can greatly shorten the optimization time down to 3% of that by traditional methods. Therefore, the proposed method is feasible in MPT applications.
