Abstract
An adaptive antenna system (20) includes a programmable reflection surface (22), a controller (24) in communication wit the programmable reflection surface (22), and a feeder element (26) outwardly spaced from a receiving side (28) of the programmable reflection surface (22). The controller (24) is operable to write a pattern (34) of reflective (36) and absorptive (42) regions into the programmable reflection surface (22) in accordance with a frequency and a direction of a received or transmitted electromagnetic wave (32). The controller (24) is further operable to write patterns (68, 80) into the programmable reflection surface (22) to dynamically adjust adaptive antenna system (20) to changing frequencies and directions of transmitted and received electromagnetic waves.
