1. A Multiple-Input, Multiple-Output (“MIMO”) antenna system for IEEE 802.11 WiFi communications, comprising:
a conductive ground plane,
a first MIMO pair of mutually spaced first antennas, mounted onto and/or configured to co-act with a top surface of said conductive ground plane, and configured to operate in the 5 GHz frequency band and/or the 2.4 GHz frequency band,
a second MIMO pair of mutually spaced second antennas mounted onto and/or configured to co-act with the top surface of said conductive ground plane, and configured to operate in the 5 GHz frequency band and/or the 2.4 GHz frequency band, and
a third MIMO pair of mutually spaced third antennas mounted onto and/or configured to co-act with the top surface of said conductive ground plane, and configured to operate in the 6 GHz frequency band,
wherein at least two first antennas are positioned in a direct line of sight with each other,
wherein at least two second antennas are positioned in a direct line sight with each other,
wherein at least two third antennas are positioned in a direct line of sight with each other, and
wherein the third MIMO pair is located inside a surface area bounded by the first antennas of the first MIMO pair and the second MIMO pair is located inside a surface area bounded by the third antennas of the third MIMO pair.
