Abstract

The embodiment of the invention relates to an antenna array for wireless energy harvesting. The antenna array comprises a first array antenna layer and a second array antenna layer arranged to be surrounded by the first array antenna layer, wherein the first array antenna layer is provided with a plurality of first antenna units associated with a first resonant frequency, the second array antennalayer is provided with a plurality of second antenna units associated with a second resonant frequency, and the first resonant frequency is different from the second resonant frequency. According to the embodiment of the invention, the size of the antenna array can be reduced while the efficiency of electromagnetic wave energy harvesting is improved by means of stacked arrangement.

Description

technical field [0001] The invention relates to the technical field of wireless energy collection, in particular to a multi-layer multi-polarization antenna array with a three-dimensional structure for collecting radio frequency electromagnetic waves. Background technique [0002] Radio frequency wireless energy harvesting technology has been proposed and developed for decades. A major problem with this technology is that radio frequency wireless energy in ordinary environments is usually very weak, and weaker energy tends to limit the efficiency of energy harvesting. Therefore, it is particularly important to improve the efficiency of wireless energy harvesting systems. [0003] In order to solve the problem of low energy collection efficiency in the radio frequency environment with low radiation intensity, the electromagnetic wave energy of multiple radio frequency bands can be collected and collected at the same time, or the electromagnetic wave energy of the same radio ...
