Hi,
I would like to know if a lcd with back metal plate will decrease the wifi signal of an esp32-s3 module.
I think so, but it doesn't hurt to ask.
In annex follow a side cut image what I want to do.
Thank's.

That will likely negatively affect antenna performance, yes. Sorry, I don't know too much about RF magic to give an indication of how much. Another thing you may want to watch out for that I've had issues with in the past: if you manage to detune your antenna by a lot, you can get issues on WiFi initing where the calibration suddenly requires a lot more power causing a brownout.
