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.

Description

technical field [0001] The present invention relates to a communication antenna, and more specifically, to an antenna element and a MIMO (Multiple-Input Multiple-Out-put) antenna device including the antenna element. Background technique [0002] With the high development of semiconductor technology, higher and higher requirements are put forward for the integration of today's electronic systems, and the miniaturization of devices has become a technical issue of great concern to the entire industry. However, unlike the development of IC chips following "Moore's Law", radio frequency modules, another important component of electronic systems, face the difficult technical challenge of device miniaturization. The radio frequency module mainly includes main components such as frequency mixing, power amplifier, filter, radio frequency signal transmission, matching network and antenna. Among them, the antenna is the radiating unit and receiving device of the final radio frequency...
