Abstract
A multi-input and multi-output antenna system is disclosed. The antenna system includes a predetermined quantity of dual-feed and dual-band antennas that are arranged into a polygon on a plane. The dual-feed and dual-band antenna includes a substrate, a grounding unit disposed on the substrate and having two opposite sides, a first radiating unit disposed on the substrate near one side of the grounding unit, and a second radiating unit disposed on the substrate near the other side. The second radiating unit has a shorting element that is electrically connected to the grounding unit. The polygon is bounded by lengthwise projection lines of the dual-feed and dual-band antennas.
