Transmitting array and beam scanning method thereof for wireless portable energy communication system

Abstract

The invention provides a transmitting array for a wireless energy carrying communication system, including an electronic control module, a power amplification module and a sixteen-element antenna array, the first radio frequency output port, the second radio frequency output port, and the third radio frequency output port of the electronic control module The output port and the fourth radio frequency output port are respectively electrically connected to the radio frequency input ports of four independent power amplification modules through coaxial lines; the sixteen-element transmitting antenna array includes four sub-arrays, and the radio frequency ports of the four sub-arrays are respectively connected to the four The radio frequency output end of the power amplification module is electrically connected. A beam scanning method is also provided correspondingly. The transmitting array has the advantages of high gain, high energy transmission efficiency, and long energy transmission distance. The feed phase of each port is obtained through the antenna structure parameters and the intended direction of beam scanning, so that each RF output port of the electronic control module outputs a signal carrying the feed phase. After power amplification, it is radiated through the antenna array to complete the beam. Scanning and long-distance energy-carrying communication.
