Abstract
A capacitively back-coupled wireless terminal () comprises a PCB () having a ground conductor () on one surface. A back coupling capacitor (C) is carried by the ground conductor. An elongate slot () is provided in the ground conductor to widen the bandwidth. An electromagnetic shield () is provided on the side of the PCB () which in use is facing a lossy dielectric in order to reduce the SAR. The shield is disposed adjacent to, but spaced from, the slot () in the ground conductor and the back coupling capacitor. For narrowband operation the slot may be omitted and/or the spacing between the PCB () and the shield () may be reduced.
