In this paper, the theoretical and simulated results of rectangular microstrip are presented which can be utilized for multi-frequency operation. For this purpose, two rectangular microstrip antennas are designed with center frequencies 9GHz and 5.67GHz. Various parameters such as width, dielectric constant & effective length are calculated. Then the antenna impedance is matched to 50ohm of coaxial fed for maximum power transfer. Now the designed structure is rearranged for multi-frequency operation by connecting two microstrip antennas at corner with corner excitation.
