Abstract
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.
