1. An antenna system, comprising:

  • a modal antenna comprising a driven element and a parasitic element positioned proximate to the driven element, the modal antenna operable in a plurality of different modes, each mode associated with a different radiation pattern;

    a radio frequency circuit; and

    a transmission line coupling the radio frequency circuit to the modal antenna;

    wherein the radio frequency circuit is configured to modulate a control signal onto an RF signal to generate a transmit signal for communication over the transmission line to control the antenna systemwherein the RF signal is defined within a first frequency band, and the control signal is defined within a second frequency band that is distinct from the first frequency band.
