Enhanced mimo communication systems using reconfigurable metasurface antennas and methods of using same

A transmitting antenna, the antenna comprising:

• a cavity;
• a plurality of RF ports for generating a feed wave within the cavity;
• and
• a plurality of sub-wavelength artificially structured material elements as arranged on a surface of the first cavity as RF radiators, wherein the antenna is configured to generate a plurality of radiation patterns respectively corresponding to the first plurality of ports.

A receiving antenna, the antenna comprising:

• a cavity and a plurality of sub-wavelength artificially structured material elements arranged on a surface of the cavity;
• and
• a plurality of RF ports coupled to the cavity;
• where the antenna is configured to receive energy with a plurality of receive radiation patterns respectively corresponding to the plurality of ports.

A method for MIMO communication between a first antenna and a second antenna, the method comprising:

• generating a feed wave within a first cavity of a first antenna from a first plurality of RF ports, a first plurality of sub-wavelength artificially structured material elements as arranged on a surface of the first cavity as RF radiators,
• simultaneously forming a plurality of radiation patterns respectively corresponding to the first plurality of ports;
• and
• independently adjusting each of the plurality of metasurface elements to obtain desired radiation patterns.
