The MMDS band is 2.5-2.69 GHz. If the antenna is a dipole, then it's dimension will be half a wavelength (ignoring effects from the PC board). So the wavelength your antenna is designed for is roughly 300 MHz/(.05m * 2) = 3GHz (ignoring effects from the PC board). That's close to 2.5-2.69 GHz. That said, I doubt that the antenna would be effective in the 2.4-GHz ISM band without some tweaking. If the antenna is a plain dipole, then you might be able to solder some extra wire onto the ends of the dipole to lower it's resonant frequency to the ISM band, but that really would require the use of a network analyzer to tell you when you've added the proper amount of wire!
