1. A handheld wireless device comprising:

  • a printed circuit board comprising a ground plane;

    communication circuitry on the printed circuit board;

    antenna feeding means coupled to the communications circuitry;

    a battery coupled to the communication circuitry;

    an antenna connected to the antenna feeding means and comprising a multilevel conducting structure, substantial portions of the multilevel structure being formed of a plurality of polygons;

    wherein the plurality of polygons comprise geometric elements identifiably defined by a free perimeter thereof and a projection of the longest exposed perimeter thereof to define the least number of generally identifiable polygons within a region;

    wherein at least two polygons of the plurality of polygons are coupled by a conducting strip narrower in width than any one of the at least two polygons; and

    wherein at least two polygons of the plurality of polygons are separated by a non-straight gap contributing to tuning a frequency behavior of the antenna.
