1. A modal antenna integrated battery assembly, comprising:

  • a battery assembly having an inner portion enclosed within a battery housing, said inner portion including an anode, cathode, and a separator positioned therebetween; and

    a modal antenna integrated within said battery assembly, said modal antenna comprising;

    a first antenna element positioned above a ground plane and forming an antenna volume therebetween;

    a first parasitic element positioned outside of said antenna volume and adjacent to said first antenna;

    a first active tuning element associated with said first parasitic element, said first active tuning element adapted to vary a current mode about said first parasitic element for actively steering a radiation pattern associated with said first antenna element;

    a second parasitic element positioned within said antenna volume; and

    a second active tuning element associated with said second parasitic element;

    said second active tuning element adapted to vary a reactive coupling between said first antenna element and said second parasitic element for actively tuning a frequency characteristic associated with said first antenna element.
