Patent 11205847 was granted and assigned to Taoglas on December, 2021 by the United States Patent and Trademark Office.
5-6 GHz wideband dual-polarized MIMO array antennas are disclosed. The antennas comprise a double layered PCB, a single layered PCB and a plurality of microstrip patch antennas. The microstrip patches are radiating elements which are coupled to apertures in the ground plane. The aperture coupling avoids the need for complex multi-layered boards with plated via holes. Standard SMA connectors can be used with the array antenna.
