Asymmetric dipole antenna assembly

An asymmetric dipole antenna assembly for a hand-held communications device having a transceiver circuit including a signal output and a ground plane, said antenna assembly comprising:

• a first dipole half including a first conductor trace disposed upon a first dielectric substrate, said first conductor trace having a first end and an electrical length of approximately one quarter of a predetermined wavelength, said first conductor trace being operatively coupled to the ground plane proximate the first ends said first dipole half being disposed near an upper portion of the hand-held communications device and away from a user's hand during operation;
• a second dipole half including a second conductor trace disposed upon a second dielectric substrate, said second conductor trace being operatively coupled to the ground plane;
• said first conductor trace being coupled a predetermined isolation distance away from the second conductor trace;
• and
• said first conductor trace being operatively coupled to the transceiver circuit signal output at a predetermined distance away from the first end.
