This paper represents the transformation of frequency of the microstrip patch antenna from 5.2 to 3.5 GHz for use in WiMAX applications. For a frequency shift, a large varying change in dimensions is required to make it reach to a particular resonant frequency. It has been shown that an increase in the dimensions of the substrate, patch and ground as well as a decrease in the dimensions of feed line and a decrease in the gap between the patch and feed line causes a prefect jump in frequency from 5.2 to 3.5 GHz. In addition to varying the dimensions, a slot is added at the rear side of the antenna in the ground which helps to cancel another band arising at 7 GHz. This helps for a single resonant frequency at 3.5 GHz to exist instead of arising of the dual band feature.
