In this paper, the authors design a circular microstrip antenna in X band. In designing of CMSA the first step is the selection of substrate, which in their project is chosen as RT Duroid 5870 with a height of 1.59cm and dielectric constant of 2.2. The designed frequency is selected as 9.8GHz. The design procedure is presented which includes calculation of parameters of Circular Micro Strip Antenna (CMSA) such as radius, effective radius, effective dielectric constant and input impedance. After calculating the various parameters the input impedance of patch antenna is matched with the coaxial feed.
