The defender has previously worked with Wimbledon manager Terry Brown while at Aldershot.
Brown told BBC Sport: "I needed to get a player in who could play a few games and help see us through.
"Will is a player I worked with for three years at Aldershot Town and I know what he can do."
Antwi spent last season at Luton and Grimsby, and has three caps for his national side, Ghana.
