Let me expand on how the body is designed. There appears to be some confusion on where the antennas are. Here is an image showing the bare case from the inside where you can see the isolation of the antenna bands which are the top & bottom sections of the body:

If you look at the green marked sections you can see there are two isolators the white plastic and the black injection that glues things together. How this is done can effect the effectiveness of your phones ability to send & receive signals. Many knockoffs don't use the dual isolators so the effectiveness of the antennas can be effected as the material choice may not offer enough impedance.
Here are the two antennas upper bus bar assembly and the lower antenna cable

There is one more antenna piece the logic board bus bar assembly which also has the NFC antenna the rectangular bar, Unlike the other antenna's this one is aligned right at the insulator (just enough of a signal window) so its focused directly down:

The screws that hold the bus bar need to be spotless (nothing underneath the screws head). Make sure you wipe the surfaces with a reagent isopropyl alcohol as you don't want the impurities to interfere with the signal as well as your finger oils. The logic bus bar also has a label on it which isolates it from the display back panel if the table is missing or shifted it can effect the signal.

A phone thats gotten wet can have a film of corrosion build up that effects the effectiveness of the transmission. Corrosion on the bus bars also can effect there ability to carry the signal to the case antennas and lastly the antenna screw hole surface (mounts) also can get corroded. Using a pink pencil eraser can clean off the film from the circuit board gold contacts. A more aggressive grey pen eraser can clean the case mounts. You may need replace the bus bars if they are badly corroded.
