ABSTRACT:
In accordance with an embodiment, an integrated circuit is provided that includes a substrate, a plurality of dipoles adjacent the substrate; an RF feed network adjacent the substrate and coupled to drive a plurality of output nodes with an RF signal; and a plurality of tuning circuits corresponding to the plurality of dipoles, each tuning circuit configured to load an RF signal from a corresponding one of the output nodes with a variable capacitance responsive to a control signal, the loaded RF signal driving the dipole antenna corresponding to the tuning circuit.
