    • There is disclosed an antenna system for mobile handsets and other devices. The antenna system comprises a dielectric substrate having first and second opposed surfaces, a conductive track on the substrate, and a separate, directly driven antenna to drive the parasitic loop antenna formed by the conductive track. Two grounding points are provided adjacent to each other on the first surface of the substrate, with the arms of the conductive track extending in generally opposite directions from the grounding points. The conductive tracks then extend towards an edge of the dielectric substrate, before passing to the second surface of the dielectric substrate and then passing across the second surface of the dielectric substrate following a path generally following the path taken on the first surface of the dielectric substrate. The conductive tracks then connect to respective sides of a conductive arrangement formed on the second surface of the dielectric substrate that extends into a central part of a loop formed by the conductive track on the second surface of the dielectric substrate.

    • A communications device provides variable ground plane tuning compensation. The communications device includes a radiofrequency antenna configured to generate an electromagnetic field, a ground plane assembly electrically coupled to the radiofrequency antenna, and a variable impedance compensation network electrically connected to the ground plane assembly. The ground plane assembly is configurable between a first physical configuration and a second physical configuration. Each physical configuration presents a different ground plane assembly impedance to the electromagnetic field of the radiofrequency antenna. The variable impedance compensation network provides a compensation impedance for each physical configuration of the ground plane assembly. The compensation impedance of the variable impedance compensation network and the ground plane assembly impedance of each of the physical configurations combine to tune mutual electromagnetic coupling between the ground plane assembly and the radiofrequency antenna to satisfy a predetermined operational tuning condition for the communications device in each physical configuration.
