Abstract

The paper presents an overview of a new high-gain beam-steering antenna method, which makes use of printed metasurfaces for near-field phase transformation. This beam-steering technology can play a vital role in a variety of space and ground systems where steering a high-gain beam is required. The concept of near-field phase transformation yields antenna systems with a very low profile (small height). In our systems, which can be manufactured at low cost, the base antenna and the RF connections are completely stationary; there are many choices for the base antenna depending on the application. These antenna systems are planar and can be concealed in shallow spaces in existing structures, unlike traditional mechanically steered high-gain antennas. The only moving parts are two very thin totally passive rotating metasurfaces, placed very close to the base antenna. They can be remotely operated using a pair of stepping motors, which may be powered by a solar panel. Contrary to phased arrays these antenna systems are extremely efficient even in millimeter-wave bands, can handle much higher power levels with negligible distortion and non-linearity. The unique features of these antennas mean that they are useful on both stationary and mobile platforms including trains, planes, and emergency vehicles.
