Abstract
The present disclosure is a metamaterial-based object detection system. An intelligent antenna metamaterial interface (IAM) associates specific metamaterial unit cells into sub-arrays to adjust the beam width of a transmitted signal. The IAM is part of a sensor fusion system that coordinates a plurality of sensors, such as in a vehicle, to optimize performance. In one implementation, an MTM antenna structure is probe-fed to create a standing wave across the unit cells.
Claims20
A sensor system, comprising:
- a dielectric layer having a plurality of metamaterial unit cells configured thereon as an array;
- a plurality of varactors coupled to the plurality of metamaterial unit cells;
- and
- an Intelligent Antenna Module (“IAM”), the IAM adapted to:
- detect a target in a section of a field of view;
- assign a subset of the plurality of metamaterial unit cells into a sub-array;
- and
- adjust a subset of voltage controllers associated with the sub-array to cause the sub-array to transmit a signal having a bandwidth to focus on the target.
