Abstract

Low-cost and efficient methods of steering highly directive antenna beams will play a major role in emerging communication systems. This paper outlines a method based on near-field phase transformation, to steer the beam of a fixed high-gain antenna. It has been implemented and tested using two rotating metasurfaces placed at sub-wavelength spacing in the near-field region of a base antenna. This method yields low-profile and planar antenna systems that can steer beam to any direction within a large conical region. Unlike mechanically-steered dish antennas, the height and volume of the antenna system remain constant while steering. Only two thin metasurface require rotation; the rest of the antenna system, including the high-gain base antenna, is totally stationary. Due to lack of active devices, these antenna systems are more efficient, do not suffer from thermal issues and non-linear distortion, and can handle more power.
