1. A wireless communications terminal, comprising:

  • an antenna array having a plurality of antenna elements, each of which is configured to apply a phase shift to a signal transmitted by the antenna element; and

    a beam steering controller configured to;

    steer a main beam of the antenna by controlling the phase shifts applied by the antenna elements,detect a failure of an antenna element, andin response to detecting the failure of the antenna element;

    disable the failed antenna element,modify the phase shifts applied by remaining ones of the antenna elements;

    wherein the wireless communication terminal is configured to;

    modulate signals transmitted by the antenna using at least one of a first signal constellation and a second signal constellation; and

    switch from using the first signal constellation to modulate signals prior to detecting the failure of the failed antenna element to using the second signal constellation to modulate signals in response to detecting the failure of the failed antenna element.
