1. An antenna system comprising:
a modal antenna operable in a plurality of modes, each of the plurality of modes associated with a different radiation pattern;
a tuning circuit configured to control the modal antenna to operate in each of the plurality of modes;
a transmission line coupled to the tuning circuit; and
one or more control devices configured to:
modulate a control signal onto a radio frequency (RF) signal to generate a modulated signal for communication over the transmission line to the tuning circuit; and
generate an acknowledgement signal based at least in part on the control signal, wherein:
the control signal comprises a data frame having a plurality of bits; and
the one or more control devices are configured to encode the plurality of bits associated with a selected mode of the plurality of modes in accordance with a coding scheme, the coding scheme specifying a unique code for a general acknowledgement request and a plurality of specific acknowledgement requests.
