Abstract
Passive or active pixelized antenna structures are described in which the radio-frequency (RF) tuning of individual antenna pixel elements, the connections of individual antenna pixel elements to other antenna elements, and optionally the local phase of individual elements or groups of elements, is varied and controlled using tunable elements. Efficient and low-cost control of a large number of tunable elements is provided by matrix addressing techniques.
