Location of Bluetooth and WiFi antenna HTC One S

I just replaced the screen of a HTC One S beatsaudio. But for some reason, both WiFi and Bluetooth are down now. I don't know if I damaged something by accident during te repair simply because I don't know the location of those antennas. I've tried a factory reset, so I pretty sure it's not a software issue...

Is there someone who does know this?

If requested, I can provide you some photos.

Thanks in advance
