Where is the wifi and Bluetooth 2.4ghz antenna

My LG G5 wifi works good at 5ghz , but at 2.4ghz the signal is poor. And the Bluetooth signal is bad too unless I put my moto360 at the screen of the phone. So I wonder maybe it lacks a wifi & Bluetooth antenna.Can you tell me where is the antenna? I can get a new one then install it。

Hi,

Here is a link to the Ifixit guide to teardown a Lg G5.

At step 14 in the guide it shows the placement of the WiFi/BT controller chip, highlighted in a red box. As there are no obvious antenna connections nearby and the complete parts teardown doesn't show any separate antenna leads, I suspect that the antenna(s) are most probably coils mounted on the board itself. If this is correct either one of the coils is loose or the controller chip's section for 2.4GHz is faulty. BT operates on the same frequency so it would use the same antenna.
