Problems solved by technology

Therefore, the method of realizing directional beams based on phased array antennas is not suitable for large-capacity, high-speed communications in wireless ad hoc networks
In addition, a phase conjugation circuit design method for direction traceability antennas has also been proposed (Xie Huan, Yan Shu, a phase conjugate circuit design method for direction traceback antennas), but direction traceback antennas can only solve the problem of directional beams at the transmitter , there are defects when used in wireless ad hoc network communication systems

Abstract

The invention relates to a wireless ad hoc network antenna array with an omnidirectional beam mode and a directional self-tracking beam mode. The antenna array is structurally a cylindrical conformalantenna array and comprises a plurality of dual-polarized antenna units and correspondingly arranged mode switching switches. When the antenna array receives signals, the working mode of the antenna array is switched into the omnidirectional beam mode through the mode switching switches, so that the spatial pattern of the antenna array is an omnidirectional beam. When the antenna array transmits signals, the working mode of the antenna array is switched into the directional self-tracking beam mode through the mode switching switches, so that the spatial pattern of the antenna array is consistent with the direction of a received guide signal. The antenna array can meet the requirements of wireless ad hoc network communication on a transmitting and receiving antenna; the signal to noise ratio of signals can be improved when the signals are received; full-airspace beam scanning is not needed when the signals are transmitted; the excitation amplitude and phase of the antenna array do not need to be calculated and adjusted, so that the communication link establishment time can be shortened, and the real-time performance of networking and signal transmission is improved.

Description

technical field [0001] The present application relates to the technical field of networking communication, in particular to a wireless ad hoc network antenna array with dual modes of omnidirectional beam and directional self-tracking beam. Background technique [0002] The wireless ad hoc network has the remarkable advantages of large capacity, high speed, and high flexibility, so it has been widely used in the fields of UAV swarm communication, Internet of Things, and regional emergency communication. [0003] In the existing wireless ad hoc network communication system, each node generally uses a monopole antenna or a dipole antenna to transmit and receive communication signals. However, the beams of monopole antennas and dipole antennas are omnidirectional beams, and the antennas have no directivity in the airspace, so the communication signals between nodes are prone to crosstalk, resulting in a decrease in signal transmission rate and network capacity. It is difficult ...
