Microstrip circular and square structural ring patch antenna because of most plasticity for receiving an transmitting the signals and also application to driver the active devices are used. An accurate modified wolfe model (MWM) is applied to compute the effective dynamic dielectric constant for detremination of resonant frequency microstrip patch antenna circular and square ring without cover. The results obtained from (MWM) have been compared against the result of experimental and other theoretical methods which have very good agreement. Then accuracy of calculated resonant frequency by the (MWM) for dominant mode is about 0.5%. Moreover we calculate the supperstrate effect on the resonant frequency dominant and higher order modes of circular and square ring, but the other methods dose not applicable for calculation of the supperstrate effects on the resonant frequency.
