Abstract

A multiple-input-multiple-output (MIMO) antenna (10) includes a first radiating element (12a) connecting to a first feed-in element; a second radiating element (12b) connecting to a second feed-in element; and a connecting element (16) connected to the first radiating element (12a), the second radiating element (12b) and a grounding component, configured to provide a grounding-current path from the first radiating element (12a) and the second radiating element (12b) to the rounding component.
