1. A wireless handset comprising an antenna array, the antenna array comprising:

  • an active antenna element disposed on a first side of a circuit board,two passive antenna elements disposed on a second side of a circuit board;

    impedance components, coupled to the passive antenna elements, disposed on the second side of the circuit board;

    a transceiver, couple to the impedance elements, disposed on the second side of the circuit board;

    resonant shapes, coupled to the passive elements, disposed on the second side of the circuit board;

    a first ground structure, coupled to the active antenna elements, disposed on the first side; and

    a second ground structure, couple to the first ground structure, disposed on the second side;

    wherein a thickness of the circuit board provides a differential in a planar location of the passive elements with respect to the active element.
