Antenna element and multiple-input multiple-output (MIMO) antenna device

Abstract

The invention relates to an antenna element. The antenna element comprises a dielectric substrate and at least two antenna units arranged on the dielectric substrate, wherein each antenna unit comprises a feed unit, grounding units arranged on the two sides of the feed unit, a feed line connected with the feed unit, and a metal structure; the feed line is coupled with the metal structure through an electric signal; and at least two antenna units have at least two electromagnetic wave resonant communication frequency ranges. A related electromagnetic wave resonant response metal structure library is made of a manual electromagnetic material, and the structures are small compared with the traditional antenna structure, so that the physical size of antennae is not limited by the physical length of half-wavelength; the corresponding antenna units are made on the basis of the metal structures; and the information sending or receiving throughput of a plurality of antenna units is improved on the basis of an MIMO technology.
