We present the results of a gravitational experiment which is based on a microwave resonator. The gravitational force of a test mass acting on the resonator is measured as a function of distance. No deviation from Newton's law on a level of a few parts in 10-4 in the near range has been found and the gravitational constant G has been determined with a relative accuracy of 1.1×10-4 to be: G=(6.6719±0.0008)×10-11 Nm2 kg -2
