1. A mobile computing device, comprising:
- a casing;
a radio frequency transmitter disposed inside the casing;
a radio frequency receiver disposed inside the casing;
a touch-screen display disposed inside the casing and comprising;
a display screen;
a touch sensor disposed adjacent the display screen and comprising;
a first and second layer, wherein the first and second layers comprise a metalized border area at least partially bordering a transparent conductive layer, the metalized border area forming electrodes for detecting a location of a touch on the touch screen display, the first layer disposed above the second layer such that the metalized border area of the first layer faces the metalized border area of the second layer; and
a far-field antenna, formed from first and second portions of the metalized border area from the first and second layers respectively, wherein the far-field antenna is operatively coupled with the radio frequency transmitter and the radio frequency receiver.

21. A touch sensor, disposed adjacent a display screen, the touch sensor comprising:
-
a first layer with a first metalized border area forming first electrodes that electrically couple with first transparent metal lead lines running in a first direction across the first layer; a second layer with a second metalized border area forming second electrodes that electrically couple with second transparent metal lead lines running in a second direction across the second layer, the second direction being different than the first direction, and the second layer disposed below the first layer in an orientation such that the first and second metalized border areas face each other; and a far-field antenna formed from first and second portions of the first and second metalized border areas, respectively. - View Dependent Claims (22, 23, 24, 25, 26)
