ANTENNA REFLECTOR SYSTEM
First Claim
Patent Images
1. A millimeter wave (mmW) antenna system comprising:
- a steerable planar antenna configured to produce a narrow beam with a scan range of less than 360 degree coverage;
a reflector configured to be positioned locally to the steerable planar antenna and at least partially within the scan range of the steerable planar antenna; and
the steerable planar antenna configured to be steered to point the narrow beam to reflect off different regions of the reflector to transform the direction of the narrow beam to provide 360 degree coverage.

Abstract
A scan range of a steerable antenna is extended using a reflecting surface or surfaces within the scan range. Various implementations may also include lenses, and the reflecting surface, lenses, or both may include meta-materials. The antenna may be steered to interact with the reflecting surface, lenses, or both to reflect the beam in a direction not possible using the antenna alone. The scan range may be extended in azimuth, elevation, or both, and beam pattern, and antenna freespace impedance may be controlled.
