No Wifi after screen replacement, missing part but unsure where from?

Hey guys I've replaced my screen and have now found since that I have poor signal and 3G and can't detect any wifi!! I have looked up a couple of threads on this but none of the solutions have worked (i.e making sure top metal bit acting as antenna is correctly installed etc) so any advice would be helpful! also this piece fell out during replacement and I have no idea where it goes and it may possibly be why the wifi is not working? (i've attached a link to the photo underneath) any help would be great.

Thanks

Hi.

Have you tried to clean this metal to metal connectors? Clean it with "with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause wireless interference issues." (quote from this guide)

Also make sure that the grounding fingers are installed below the lip in the iPhone's metal case as seen in the picture.

The part which is left over is the "grounding finger for the rear facing camera near the power button. This finger rests on top of the PCB, screwed down, and covered with the adhesive black plastic tape."
