Abstract
A method and apparatus for electrical addressing for an antenna (e.g., a metamaterial radio-frequency (RF) antenna are described. In one embodiment antenna comprising: a plurality of radio-frequency (RF) radiating antenna elements located in a plurality of rings; and matrix drive circuitry coupled to the plurality of RF radiating antenna elements to drive the antenna elements, wherein the matrix drive circuitry to uniquely address each of the antenna elements using a matrix of a plurality of rows and a plurality of columns with a non-grid-based addressing structure.
