Abstract
Examples disclosed herein relate to a radiating structure including a first metamaterial array having a plurality of elements, a second metamaterial array having a plurality of elements, a transceiver coupled to the first and second metamaterial arrays, and an antenna controller configured to adjust the first metamaterial array to scan angles in a first direction and adjust the second metamaterial array to scan angles in a second direction orthogonal to the first direction.
Claims20
A radiating structure, comprising:
- a first metamaterial array having a plurality of elements;
- a second metamaterial array having a plurality of elements;
- a transceiver coupled to the first and second metamaterial arrays;
- and
- an antenna controller configured to adjust the first metamaterial array to scan angles in a first direction and adjust the second metamaterial array to scan angles in a second direction orthogonal to the first direction.
The radiating structure of claim 4, wherein to adjust the second metamaterial array comprises to adjust a reactance of the second metamaterial array.
An antenna system to identify an object in a field of view, the antenna system comprising:
- a plurality of meta-structure transmit antennas;
- a plurality of meta-structure receive antennas orthogonal to the plurality of meta-structure transmit antennas;
- and
- an antenna controller to select one or more meta-structure transmit antennas from the plurality of meta-structure transmit antennas and one or more receive antennas from the plurality of meta-structure receive antennas as instructed by a decision engine in an object detection module.
A method of operating an orthogonal antenna system having an active aperture, comprising:
- identifying a target field of view;
- identifying a set of transmit antennas for the target field of view;
- identifying a set of receive antennas for the target field of view, the set of receive antennas orthogonal to the set of transmit antennas;
- generating a set of transmission signals;
- determining if there is a change in the target field of view to identify a new field of view;
- and
- determining a new configuration of transmit and receive antennas based upon a detection of an object in the new field of view.
