Abstract
Disclosed are an antenna unit, an antenna array, a beam scanning method, a communication apparatus, and a computer-readable storage medium. The antenna unit includes a microstrip patch antenna and a phase shifter. The phase shifter includes: a microstrip line; a liquid crystal layer, arranged between the microstrip line and the microstrip patch antenna; and a metal layer, arranged between the liquid crystal layer and the microstrip patch antenna, where a first through hole is formed in the metal layer, and the output ends of the microstrip patch antenna and the microstrip line are coupled by means of the first through hole. The antenna unit capable of implementing beam phase change is simple in structure, low in manufacturing cost, and small in weight, can be manufactured into a planar structure, and is low in profile, easy to process, easy to downsize, convenient to carry, and convenient to integrate.
