1. A MIMO (Multi-Input Multi-Output) antenna, comprising:
- a system ground plane;
an antenna ground plane, overlapping a first portion of the system ground plane;
an EBG (Electromagnetic Band-Gap) structure, formed on a second portion of the system ground plane;
a first antenna element, partly overlapping the EBG structure, and substantially extending in a first direction; and
a second antenna element, partly overlapping the EBG structure, and substantially extending in a second direction different from the first direction, wherein a distance between the first antenna element and the second antenna element is smaller than 0.5 wavelength of a central operation frequency at which the first antenna element and the second antenna element operate.

Abstract
A MIMO (Multi-Input Multi-Output) antenna includes a system ground plane, an antenna ground plane, an EBG (Electromagnetic Band-Gap) structure, a first antenna element, and a second antenna element. The antenna ground plane overlaps a first portion of the system ground plane. The EBG structure is formed on a second portion of the system ground plane. The first antenna element and the second antenna element are both disposed in proximity to the EBG structure, but substantially extend in different directions.
