Abstract

The present application discloses an antenna device, in which a scatterer structure including a Q-layer dielectric substrate is arranged above the antenna array; the target area of ​​the Q-layer dielectric substrate includes resonator elements with axisymmetric structures, the number and distribution of which meet certain requirements condition, wherein at least one resonant element is shared by the first antenna element and the adjacent second antenna element within the range corresponding to the target area on the antenna array. The technical solution of the present application reduces the spatial correlation between antenna units by arranging a scatterer structure above the antenna array, so that beam signals arriving at the antenna array can be better distinguished, signal superposition interference is reduced, and MIMO performance is improved.

Description

technical field [0001] The present application relates to the field of antenna technologies, and in particular, to an antenna device and a signal processing method. Background technique [0002] With the advent of 5G, massive multiple-input multiple-output (M-MIMO) technology has gradually become one of the most core key technologies in the 5G system. M-MIMO technology achieves higher spectral efficiency and energy efficiency by increasing the number of antenna elements. Much of the current research work on M-MIMO systems is carried out under ideal transmission conditions, i.e. without considering the physical size of the antenna array and assuming that the distance between antenna elements is large enough (large enough to the electric field between adjacent antenna elements) and the magnetic field do not affect each other). For traditional MIMO technology, due to the limited number of antenna units, ideal transmission conditions may be satisfied, but with the current deve...
