A typical half wavelength path antenna will have a first resonance at say f1. Then it will typically radiate as well at 3*f1, 5*f1, ....

By altering the feed location and geometry, the patch can be made to radiate at 2*f2 as well. So they can be multiband, but there is additional work that needs done.
