Abstract
A rotary control (102) having an antenna radiating element (202) integrated therein is provided. The rotary control (102) is formed of a knob housing (112) providing an axis of circumferential rotation (120). The antenna radiating element (202) is rotatable along the axis of circumferential rotation (120) in response to rotation of the knob housing (112). The antenna radiating element (202) is coupled to a rotatable antenna feed electrode (230). The rotary control (102) having the integrated antenna radiating element (202) may be mounted to a communication device housing having a stationary capacitive feed electrode (220). The stationary capacitive feed electrode (220) and rotatable antenna feed electrode (230) provide capacitive coupling for the transfer of RF signals to and from antenna radiating element (202) regardless of the position of rotation of the knob housing (112).
