Remove your back cover, battery, sim, memory card etc. Remove the two screws you can see. Push the aerial cover in the direction shown.
With the aerial cover removed you'll see two more screws. Remove these.

You should now have your front cover removed, like below. Remove the screw, circled. You can now remove the battery compartment.
