Hey there "Facebook":
What prompted you to rebuild your iPhone? Did you buy individual parts from eBay and then reassemble them?
The NFC antenna is the top bezel itself, the top bezel has 2.4G(wifi and Bluetooth), cellular diversity, GPS and NFC. The main feed point for GPS, cellular and 2.4G is the screw boss under the plastic add-on antenna, with a "grounding bracket" attaching it to the bezel. The plastic antenna serves as the 5G wifi antenna.
The NFC antenna feed point is the screw boss next to the camera and sleep/wake button, with a flex cable under the camera bracket serving as signal conductor.
There is an additional feed point in the middle of the bracket, it does not connect to any wireless services, however it connects to a dynamic switch to tune the top bezel dynamically to serve different bands.
The F-shaped flex cable on the back of the board is JUST a bridging cable, not an antenna in any way.
It is possible that the grounding bracket found in step 29 of the repair guide below may be missing or broken. It isn't exactly clear when the actual "antennae" is on the 6 and higher but some people believe that it consists of the upper portion of the phone itself.

Since when do idevices have NFC?
George A. tarafından
@pccheese, they've had them since the intro of Apple Pay. Apple Pay is essentially a neutered NFC that can only do Apple Pay. This is why Android Pay and Apple Pay work on the same systems. If you hold an iDevice back to back to an Android NFC enabled device, it will trigger an NFC transmission and the iDevice will try to start an Apple Pay transaction. No joke.

Sweet. To bad it doesn't work for general NFC applications though. BTW @avanteguarde, you qualify for my team and I would like it if you join. It's called "Master Techs (invite only, not exclusive)." I can't figure out out to invite, but I think if you find it you can probably send a request to invite.
