Which part exactly do I need to buy to replace embedded cellular ant.

I have my Furbo taken apart because my dog decided he didn’t want to be on film… well. He broke the connection for wifi/Bluetooth (I believe that’s what it is) I think the name is embedded cellular antenna. He had ripped the wire from antenna to device. I am just looking to replace the small chip / wire. I can’t find exact item name!!?? I hope this makes sense. Thank you
