Uniform Electric Fields


Coulomb's Law
F = kqq/r^2

Why does the intensity of a uniform electric field not get weaker in the middle? I would understand this if the intensity over distance was a linear function, but it isn't. The force near one of the plates would approach infinity, because r^2 is so small... but in the middle of the field even the forces of each side added up would not approach infinity, which means the field is not uniform. How are uniform electric fields possible?
