just as hero999 said, when it is a monopole one like whip antenna, the best antenna length should be 1/4 wavelength, but if you don't have much space to fit in a whip antenna, you can use short whip antenna and helical antenna, i have posted a picture of that. **broken link removed**
you can visit RF module external antenna design guide at solidremote to see detailed information on antenna design.
