Beam shaping for reconfigurable holographic antennas

A holographic metamaterial antenna comprising:

• a waveguide;
• a metamaterial layer coupled to the waveguide;
• control logic coupled to drive holographic patterns onto the metamaterial layer;
• and
• a non-transitory machine-readable medium that provides instructions that, when executed by the holographic metamaterial antenna, will cause the holographic metamaterial antenna to perform operations comprising:
• driving a first holographic pattern onto a layer of the antenna while a feed wave excites the layer;
• receiving an antenna pattern metric representative of a first antenna pattern generated by the antenna while the first holographic pattern is driven onto the layer;
• generating a modified holographic pattern in response to the antenna pattern metric;
• and
• driving the modified holographic pattern onto the layer of the antenna.

A method of interference mitigation for reconfigurable holographic antennas, the method comprising:

• driving a first holographic pattern onto a layer of the antenna while a feed wave excites the layer;
• receiving an antenna pattern metric representative of a first antenna pattern generated by the antenna while the first holographic pattern is driven onto the layer;
• generating a modified holographic pattern in response to the antenna pattern metric;
• and
• driving the modified holographic pattern onto the layer of the antenna to generate an adjusted antenna pattern.
