Abstract

The invention discloses a directional diagram reconfigurable phase bit antenna and a two-dimensional beam scanning array thereof, and belongs to the technical field of communication. The directional diagram reconfigurable phase bit antenna comprises a miniaturized electromagnetic metasurface, a metal patch unit, a dielectric resonator, a phase 1-bit coupling feed slot, a reflector radiation slot, a phase bit switch circuit, a reconfigurable reflector slot switch circuit, a feed microstrip line, a switch direct current bias circuit and a metal floor, a metal reflecting plate and a nylon screw. Array elements in the two-dimensional scanning digital multi-beam array based on the one-dimensional linear array are composed of directional diagram reconfigurable phase bit antennas. According to the invention, the limitation that the existing one-dimensional linear array is difficult to realize linear array two-dimensional multi-beam scanning and the limitation that a traditional digital bit array adopts a patch radiator, so that the size is large and the array is difficult to form for wide-angle scanning are solved; the problems that a traditional digital bit array is narrow in bandwidth, and a traditional two-dimensional beam scanning array needs large-scale array elements and occupies large space are solved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a phase bit antenna with a pattern reconfigurable and a two-dimensional beam scanning array thereof. Background technique [0002] At present, as an important part of the new infrastructure, the 5G wireless communication system is constantly advancing and deploying, which will accelerate the development of all walks of life and at the same time promote the improvement of people's quality of life. Different from traditional 2G / 3G / 4G wireless communication systems, 5G communication systems provide higher transmission rates, lower latency, greater capacity and more stable wireless communication services. Therefore, on the base station side, the 5G system will adopt multi-beam antennas and massive MIMO antenna array architectures working in the new frequency band. However, traditional 2G / 3G / 4G base station antennas usually use fixed-beam omnidirectional antennas or...
