Abstract
The present invention provides a MIMO antenna structure and design. A single dipole antenna stands at the center of a triangle which is formed by three PIFAs antennas, and the three PIFA antennas has equal squint angle relative to the neighbors, that is there is 120° sector angle between any two PIFA axes of three such that the dipole and the other PIFAs forms a tetrahedron. The MIMO antenna structure of the present invention is simpler in mechanics but high efficiency in performance.
