This paper describes the design of a Common feed with double Microstrip patch antenna for satellite application using FR-4 substrate. The main contribution of the paper is optimized and achieves high gain, high efficiency, very low return loss and ease to adapt in MMIC technology. The proposed antenna is capable to maintain its high performance over wireless system operating at X - band (8-12 GHz) frequency range. The antenna resonates at dual frequency band and thus the antenna becomes a necessity for many applications in recent wireless communication, such as RADAR, Microwave and Space applications. The proposed antenna is fabricated on a FR4 substrate of thickness 0.8 mm and a dielectric constant of 4.4 and tested. The proposed antenna yields a VSWR of about 1.34 (7.99 GHz) and 1.27 (9.99 GHz) under simulation and 1.033 (7.99 GHZ) and 1.098 (9.99 GHz) in measurements respectively. The figure of eight radiation pattern is achieved with antenna gain of 5.63 dBi (7.99 GHZ) and 6.52 dBi (9.99 GHz) under simulation and measured peak radiation efficiency of 97.99% (7.99 GHZ) and 98.31% (9.99 GHz) are observed for the operating bands. Finally, the experimental outcome seems very nexus with the simulated ones for the proposed antenna.
