Dual polarized base station and user equipment antenna for upper mid-band x-mimo

An electronic device comprising:

• a multiple input multiple output (MIMO) antenna comprising:
• a substrate;
• a plurality of antenna elements on the substrate and arranged according to an antenna configuration comprising:
• a rectangular antenna patch,
• a first pair of circular antenna patches supporting a first angular polarization, wherein the circular antenna patches of the first pair are coupled to opposite corners of the rectangular antenna patch, and
• a second pair of circular antenna patches supporting a second angular polarization that is orthogonal to the first angular polarization, wherein the circular antenna patches of the second pair are coupled to opposite corners of the rectangular antenna patch;
• transit (TX) processing circuitry coupled to the plurality of antenna elements and configured to provide signals to the plurality of antenna elements;
• and
• receive (RX) processing circuitry coupled to the plurality of antenna elements and configured to receive signals from the plurality of antenna elements, wherein each of the circular antenna patches of the first pair are positioned on corners adjacent to both of the circular antenna patches of the second pair.

A method of using a massive MIMO antenna comprising:

• providing signals to a plurality of antenna elements on a substrate, the plurality of antenna elements including a rectangular antenna patch, a first pair of circular antenna patches supporting a first angular polarization, and a second pair of circular antenna patches supporting a second angular polarization that is orthogonal to the first angular polarization;
• increasing port-to-port isolation for antennas elements in the plurality of antennas elements using an antenna configuration comprising the circular antenna patches of the first pair coupled to opposite corners of the rectangular antenna patch and the circular antenna patches of the second pair coupled to opposite corners of the rectangular antenna patch, wherein each of the circular antenna patches of the first pair are positioned on corners adjacent to both of the circular antenna patches of the second pair;
• and
• receiving signals from the plurality of antenna elements.
