Therefore, the realization of wireless energy transmission (WPT) enables the application of electric energy to human beings to be wider and more flexible. According to different transmission mechanisms, microwave wireless power transmission can be used for far-field radiation for long-distance transmission, but the far-field distance loss of the system exists due to divergence of a transmitting beam. With Near Field Focusing (NFF), it is theoretically possible to focus the electromagnetic wave from the emission source at a certain point in the near field region of the antenna radiation, thereby avoiding unnecessary energy loss due to beam divergence. NFF has been implemented with various antenna structures, such as parabolic antennas, lens antennas, phased array antennas, and the like. However, the difficulty of parabolic antenna processing, the complexity of phased array antenna processing and the large loss of TR components have hindered the development of NFF for WPT. The phase of each unit is adjusted through a periodic or sub-wavelength electromagnetic non-periodic arrangement structure on the super surface, beam direction control is achieved, energy is focused on one point in a near field region, and wireless energy transmission efficiency is greatly improved.
The method comprises the steps of firstly determining a unit structure of a reflective array antenna, selecting the size and the unit interval of the reflective array antenna, then selecting the positions of a feed source and a focus, irradiating electromagnetic waves emitted by the feed source onto the reflective array antenna, then calculating a compensation phase of each reflective array antenna unit according to a formula, adjusting the size of the reflective array antenna unit to meet the compensation phase, and realizing expected focusing. The method has the following defects: 1. the metal patch on the dielectric plate is a three-vibrator, and when the metal patch covers the dielectric plate, the utilization rate of the unit area of the phase shift unit is not high. 2. The antenna designed by the method cannot realize long-distance high-efficiency energy transmission due to the size and the arrangement of the focus.
