The antenna is removable and should have a threaded base. From your
description, it appears that you have successfully sheared the RP-SMA
connector from the circuit board. You should be able to unscrew and
separate the round black antenna part, from the gold square connector
part.

Depending up on the damage to the gold square connector, you have the
options of:
1. Soldering the connector back to the board. The ground connections
are easy as they have a large area to work with. The center pin might
be sheared and will require some skill.
2. Replace the connector and resolder.
3. Add a pigtail and solder the coax cable directly to the board.
4. Attach a 3.2cm insulated wire (1/4 wave at 2.4GHz) to the center
pin connection on the board and just hang it out the back of the
computer. This is not a great antenna, but might work if you're
fairly close to the access point.

Any of these should not be particularly difficult for someone skilled
in soldering. However, if you've never tried soldering before, this
might be a bit difficult.
