Abstract

A novel layout method of receiving antenna array, which is a sparse random circular aperture array (SRCAA), to raise the power transmission efficiency (PTE) for microwave power transmission (MPT) is proposed in this paper. Different from the conventional antenna array layout, the array element positions of the SRCAA are randomly and uniformly distributed in the circular region. At present, the receiving array mostly adopts the form of uniform full array in the MPT system, and most researches focus on the antenna unit itself to raise the PTE rather than the array layout. In this paper, the initial array is obtained by randomly scattering points in the fixed area, and then the array element position is optimized by the algorithm to maximize the PTE between the transmitter (Tx) and receiver (Rx) of the MPT system. At the same time, the random array element position also plays a significant role in the uniformity of the received power of the receiving array. Therefore, this paper proposes a new index to measure the performance of the receiving array. In order to verify the effective performance of the SRCAA, we carried out a series of numerical simulations. Numerical simulation results show that the SRCAA, as a high-performance and low-cost receiving array, is more suitable for the receiving array of the MPT system than the traditional uniform array.
