iPhone 4: Where are the iPhone 4 antennas' feeding and grounding points?

Wed, 02 Mar 2011 04:18:53 -0700

What sort of antenna does iphone 4 employs? Is it an IFA (inverted F antenna)? I tried to find the feeding and grounding points, particularly for the wireless antenna (WiFi, Bluetooth and GPS).

Usually and IFA has a feeding point somewhat in the middle. Unfortunately, I cannot find it. There seems to be a feeding point close to the top slit.

Is it possible then to achieve dual-band behavior? How many grounding points are there, and where?

thanks

iPhone 4: Screw Diagram with Grounds?

In my brief foray into iPhone repair, I've come to realize how important making sure I replace every single little screw on my iPhone 4. Is there a diagram that exists or can someone create one, showing all the screws that ground certain components (such as the long screw at the top being necessary for wifi/GPS)?

That would help immensely as some money could be saved on parts when I know there is just a screw that needs to be in place in order for some components to function properly. I think this may be the case with my non-functional mic and crappy sounding speaker.

Thanks!
