#Apple granted #patent for #wireless antennas built into Mac #keyboards

The U.S. Patent & Trademark Office granted Apple a batch of 20 patents on Tuesday, including one for an invention that describes integrating wireless antennas into a keyboard.

Entitled 'Antennas for electronic devices,' Apple's filing describes 'key antennas,' or radio-frequency transmitters mounted inside individual keys of a keyboard, for devices such as a laptop computer. Apple suggests that fitting a key with an antenna resonating element, such as a flex circuit containing a strip of conductor, a piece of stamped metal foil and a length of wire, could serve as an improved antenna design.
