One major reason for the increasing use of microstrip patch antennas in the existing satellite communication system is due to their compactness, lightweight nature, and ease of fabrication. In this study, an innovative microstrip patch antenna for satellite communication in Ku band was designed and analyzed. The design and simulation of the antenna were performed using CST studio suite software. The resonant frequency obtained from the antenna is 16.056 GHz, where the return loss and voltage standing wave ratio are –42.98 dB and 1.014, respectively. Furthermore, the antenna has bandwidth of 2.52 GHz, gain of 5.78 dBi, and directivity of 6.25 dBi. Based on comparative study of the designed antenna with the reference antenna, it can be concluded that the proposed antenna performs better than the reference antenna in terms of bandwidth and S-parameters
