ABSTRACT:
A radio frequency field strength enhancement system (402) having a member (404) with at least one tuning impedance (405) for adjusting a desired frequency response associated with the member (404) and means for retaining (408) the member (404) in close proximity to a radio frequency communication device (401) having an integrally mounted antenna system (214). When the radio frequency communication device (401) is brought within close proximity of the RF field strength enhancer (402), the power received or transmitted by the integrally mounted antenna system (214) in the RF communication device (401) is enhanced.
