[Q] How to reattach antenna in Xperia Z

I took out my old antenna in Xperia Z, I'm trying to attach a new one together with these metal pieces to the inside side wall. Anyone has got any pictures of how should it look attached or have any advices about the position of the metal pieces (can't remember how was it before) or how to do it right? Thanks in advance

Here are the pictures of the inside (sorry, cannot link pictures directly for view as a new user)
