Patent ID: 8519966

Claim:
A touch screen for use in a communication device having a transceiver that communicates radio frequency (RF) signals with at least one remote station, the touch screen comprising: a display layer for displaying information; an inductor grid, coupled to display layer, that includes a plurality of inductive elements; at least one switch matrix, coupled to the inductor grid, that selects a selected one of the plurality of inductive elements in response to at least one selection signal; a driver, coupled to the at least one switch matrix and the inductor grid, that generates the at least one selection signal and that drives the selected one of the plurality of inductive elements to detect a touch object in proximity to the selected one of the plurality of inductive elements and that generates touch screen data in response thereto; and a plurality of microelectromechanical system (MEMS) capacitors that couple together a group of the plurality of inductive elements to form an antenna by connecting one end of ones of plurality of inductive elements to another end of an adjacent ones of the plurality of inductive elements in the group through a corresponding one of the plurality of MEMS capacitors and that couple the antenna to the transceiver to send and receive the RF signals.
