Unknown component in the lower right side of the usb connector.

More precisely, if you put the motherboard facing the writing of the version up, we have on the lower right a single component connected to a SMD, the component has the characteristics of a black square with a hole with a golden outline.

What's this?

it is also found on the signal card connected to the motherboard with the antenna.
