US Patent 11394111 Electronically reconfigurable antenna

A reconfigurable antenna systems includes a set of envelopes of active metamaterial panels, each envelope in the set being shaped to approximate a surface of at least partial revolution of a curve about an axis, wherein the surface defines a focal locus; a wideband antenna array disposed within the focal locus; and a controller, coupled to the panels, configured to activate each one of the panels, so as to control a property of each of the panels, the property selected from the group consisting of transmissivity, reflectivity, absorption, phase, polarization, bandwidth, angle sensitivity, resonant frequency, and combinations thereof.
