Problems solved by technology

In order for the MIMO system to have better performance, the antenna elements must be uncorrelated (lower coupling), however, the space reserved for the antennas in the mobile device is very limited, so that the spatial distance between the antennas is not large. May be greater than or equal to a wavelength

Abstract

The invention provides a high-isolation polarization diversity microstrip MIMO antenna for an intelligent terminal. The antenna is composed of a first antenna unit, a second antenna unit, and a dielectric substrate. The first antenna unit and the second antenna unit are orthogonally arranged and share the dielectric substrate. Each antenna unit consists of a printed monopole sub radiation patch, amicrostrip line and a metal grounding plate; the printed monopole sub radiation patch and the microstrip line are arranged on the upper surface of the dielectric substrate, wherein the diameter sideof the printed monopole sub radiation patch is parallel to the short side of the dielectric substrate and the microstrip line is arranged at the edge of the long side of the dielectric substrate and deviates from the center at a first preset distance; and the metal grounding plate is arranged a the lower surface of the dielectric plate right below the microstrip line and is aligned with two adjacent right-angle sides of the lower surface of the dielectric substrate. A signal line of a radiation system of a mobile terminal is connected directly with a feed microstrip line of the microstrip lineof each antenna unit. The MIMO antenna has advantages of having low manufacturing cost, being easy to process, being convenient to batched production, and having the great practical application value.
