Abstract
A reflector antenna that includes a feed for generating a radio frequency (RF) signal, and a metasurface reflector for reflecting the RF signal originating from the feed. The metasurface reflector includes an array of cells each having a volume of liquid crystal with a controllable dielectric value enabling a reflection phase of the cells to be selectively tuned to effect beam steering of the reflected RF signal.
