1. A communication device with an improved antenna system, the device including a housing partially containing the antenna system along with a transceiver, the system comprising:

  • an antenna being electrically coupled to the transceiver;

    a first conductor coupled to a ground connection near the antenna and being contained within the housing and located distally from such surfaces of the housing that can be held by or placed in proximity to a user, the first conductor presenting a low impedance at operating frequencies of the communication device such that RF currents are attracted onto the first conductor; and

    a second conductor coupled to the ground connection of the first conductor and being contained within the housing, the second conductor presenting a high impedance at operating frequencies of the communication device such that RF currents are diverted away from the second conductor.
