Of course, you always have asked yourself. "Where did the put the antenna in those NFC Phones?" -- So, after opening serveral devices, here are a couple of pictures, which illustrate where manufacturer put the antenna of their NFC Devices. After opening the devices, they have been put togehter again and are of course working. Thanks to Michael Roland for his Efford in this case!
Nokia 3220
The Nokia 3220 host the NFC Functionality in the external Shell. On the PCB you can cleary see the antenna at the edge. The Antenna is very close the reference design for an ISO 14443 reader/writer device.
Nokia 6131
Nokia's 6131 is probalby the best know NFC device yet. The antenna design itself is quite special and especially dedicated to touch-interacts. But as there is no touchmark on the device itself, it might be a bit tricky for a user to know, how to put two NFC devices together to establish a communcation.
Sagem X700n
Sagem's devices is using the 2nd version of the SWP protocoll for the communcation with the UICC. The device is make for emulation as well as reading/writing Type-B Task. P2P is not implemented yet. Like Nokia's 3220, the antenna is in the backside of phone in the cover for the battery.
Nokia 6212
Nokia's most recent NFC device came up with a new approach for the antenna design. In this case, the antenna is integrated into the body of the phone. This design allows to establish communication with other NFC devices without requiering a special touch area. A backdraft of this design is the case, that there are problems when reading smaller tags. Nokia announced that this issue will be fixed in the upcoming 6216.
Benq T80
The Benq T80 come with a secure Element on a micro-SD Card. The Benq has an antenna inside the battery-cover, which is protected by a fero-magnetic shield. The Antenna has the size of the reference antenna as in the Nokia 3220 and is connected thru a two-pin connector with the body of the device.

Is the information about the 6216 beeing a better reader than 6212 (may be more like 6131?) official?
I have been looking for this information and haven't found it on the NFC Discussion Board.
