Based on your photo, the part you accidentally broke is one of two test pads used in the signal strength adjustment for the cellular antenna system. See this photo.

You'll have to get this part repaired before you can solve your signal strength problem.

I have no idea if the part can be individually repaired. You'll have to check with a repair shop to see if it's possible.
