Abstract
A communication device includes a conductive chassis, an electrical feed positioned within the conductive chassis and configured to supply a communication signal, an edge antenna at least partially formed in the conductive chassis at an edge of the communication device, and a conductive coil positioned within the conductive chassis in proximity to the edge antenna. The conductive coil is configured to receive the communication signal from the electrical feed and to generate a magnetic field corresponding to the communication signal that inductively drives the edge antenna to radiate a radio frequency signal corresponding to the communication signal.
