Abstract
Control for a portable communication device (300) includes a control knob (304) which has an outer shell (610, 610a) at least partially formed of a dielectric material. The control knob is sized and shaped to facilitate fingertip control of the portable communication device, and has an integrated antenna (608, 608a) disposed within the outer shell. An axial member (612, 708) is provided on which the outer dielectric shell and the antenna are mounted to facilitate rotation of the control knob. A control device (606, 606a) is provided which is configured to control at least one electronic circuit (806) of a portable communication device responsive to a user rotation of the outer dielectric shell. The integrated antenna (608, 608a) is arranged to interface to at least one radio frequency communication circuit of a portable communication device.
