Actually it is circular but usually the sun needs to be quite low in the sky for the angle of the sunbeams hitting the raindrops to be suitable to create a rainbow visible from the ground. But, when that happens, a part of the rainbow is cut-off by the horizon and so it appears semicircular.
Full circles are rare but have been seen/photographed.
