The invention discloses an MIMO-phased-array antenna device, system and implementation method. The antenna device comprises a micro-strip array antenna module, a power distribution module and a phase shifter module. The micro-strip array antenna module is used for radiating electromagnetic field energy to surround space with a preset frequency and a preset data bandwidth through an array formed by multiple broadband paster array elements. The power distribution module is used for dynamically adjusting the radiant power of the array elements in a preset range through a feeder line circuit. The phase shifter module is used for establishing data communication connection between terminals successfully scanned and a base station on the basis of MIMO channels after scanning on all terminals in a communication space is completed by adjusting the phases of the array elements.
Description
technical field [0001] The present invention relates to an antenna system, in particular to a MIMO-phased array antenna device and system, and the principle and flow of mutual work between a base station and a terminal based on the antenna system. Background technique [0002] Wireless communication is one of the most active research fields in the world today. The main problem facing wireless communication at present is how to increase the data transmission rate and ensure the security of wireless communication. However, the two traditional resources for increasing the data transmission rate, frequency bandwidth and transmission power, are almost saturated. Therefore, wireless communication technology based on MIMO Emerging as the times require, how to efficiently apply MIMO technology is an important direction for the development of wireless communication in the future. [0003] The aspects that can be optimized in the existing antenna system are as follows: (1) The antenn...
