Hello, we don't have a schematic. In phones, the arrangement of antennas (receivers and transmitters) for WIFI, GPS, GSM is complex, and it differs for each phone - at the manufacturer, a large group of scientists, I would say, deals with this issue. The best way to see or read about how this works is here http://www.antenna-theory.com/design/gps.php but it requires knowledge of English and knowing a bit of terminology.
