Abstract: Antennas with tunable elements and methods for using the same are disclosed. In some embodiments, an antenna comprises: a plurality of radio-frequency (RF) radiating antenna elements, wherein each antenna element of the plurality of RF radiating antenna elements comprises a tunable element, circuitry connected to the tuning element to set a voltage on the tunable element. In some embodiments, the circuitry comprises a voltage storage structure, a first transistor having a first gate connected to the voltage storage structure, a first source connected to the tunable element, and a first drain for coupling to a constant voltage source, and a data voltage input terminal operable to apply a voltage to the voltage storage structure and to the first gate to determine current through the first transistor.
