Abstract
A method and apparatus for using Euclidean modulation in an antenna are disclosed. In one embodiment, a method for controlling an antenna comprises mapping a desired modulation to achievable modulation states, mapping modulation values associated with the achievable modulation states to one or more control parameters, and controlling radio frequency (RF) radiating antenna elements using the one or more control parameters to perform beam forming.

A method for controlling an antenna having a plurality of antenna elements, the method comprising:
- determining modulation states for the plurality of antenna elements based on desired modulation states and achievable modulation states that are based on distances from one or more of the desired modulation states, the achievable modulation states being mapped to voltages applied to the antenna elements;
- mapping modulation values associated with achievable modulation states to one or more control parameters;
- and
- controlling radio frequency (RF) radiating antenna elements using the one or more control parameters to perform beam forming.
An antenna comprising:
- a metasurface having a plurality of RF radiating antenna elements;
- a controller coupled to the metasurface and having modulation logic to:
- determine modulation states for the plurality of antenna elements based on desired modulation states and achievable modulation states that are based on distances from one or more of the desired modulation states, the achievable modulation states being mapped to voltages applied to the antenna elements;
- map modulation values associated with achievable modulation states to one or more control parameters;
- and
- drive circuitry coupled to the metasurface and the controller to control the RF radiating antenna elements using the one or more control parameters to perform beam forming.
A method for controlling an antenna having a plurality of radio-frequency (RF) radiating antenna elements, the method comprising:
