1. An antenna for a wireless communication device for receiving and transmitting a communication signal said antenna comprising:

  • an asymmetric dipole comprising a radiator portion defined by conductive traces on a printed wiring board having associated electronic componentry, and a resonator portion having a conductive trace defined thereupon, said conductive trace being electrically coupled to the radiator portion at a first location and being electrically coupled to a feedline line of the communication device at a second location away from the first location; and

    a dual band parasitic element disposed away from a user during operation of the wireless communication device relative to the asymmetric dipole, said dual band parasitic element comprising a conductive trace upon a dielectric substrate, said conductive trace include a pair of opposed ends, each of the pair of ends including an inductor portion and a capacity hat portion.
