The present invention relates to an antenna which is configured to plug into a retractable connector on an electronic apparatus. Some embodiments of the present invention may be configured to plug into common RJ-11 or RJ-45 jacks allowing devices equipped with these jack to utilize external antennas to increase range and functionality. Further, some embodiments of the present invention comprise at least a partial ground plane located in the antenna plug which connects to a jack. The present invention also comprises connectors such as RJ jacks which comprise ground plane elements which may be used to improve antenna range and efficiency.

A contact system is disclosed that includes a metal contact clip capable of being surface-mounted to a printed circuit board that facilitates the electrical coupling of the opposing conductive covers in a circuit card assembly having conductive enclosures with a reference potential, such as ground, on the printed circuit card which provide protection against electrostatic discharge (ESD) on the printed circuit card. The clip spans a cut-out region on the printed circuit card and includes opposing tabs the extend from the spanning portion for electrically contacting the conductive covers. The clip further includes geometries such as springs for exerting forces upon the conductive covers thereby providing a reliable contact interface with the conductive covers.
