Title:
MULTIPLE-INPUT MULTIPLE-OUTPUT ANTENNA, BASE STATION AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/124490
Kind Code:
A1
Abstract:
The present application provides a multiple-input multiple-output antenna, a base station comprising the multiple-input multiple-output antenna, and a communication system comprising the base station. The multiple-input multiple-output antenna comprises a plurality of antenna units; a dielectric plate is provided in each antenna unit, and the dielectric plate is made from a material having a near zero refractive index, so that a phase difference between any two of the electromagnetic wave beams, emitted to the dielectric plate and transmitted by different channels, becomes larger after being refracted by the dielectric plate as compared to that before being refracted. In the present application, electromagnetic wave beams need to pass through the dielectric plates and then are transmitted to the feed source, so that before being received by the feed source, the electromagnetic wave beams transmitted by different channels pass through the dielectric plates for phase difference amplification, and therefore the phase difference between the electromagnetic wave beams transmitted by different channels and emitted from the dielectric plates is increased, thus reducing the correlation between electromagnetic beams transmitted by different channels, so that the antenna units are able to perform super-resolution on the electromagnetic wave beams transmitted by different channels.
