High gain patch antenna for CubeSat

A design of high gain patch antenna system suited for inter-satellite and earth observatory is presented. The antenna consists of four patch antenna array designed for maximum gain, this antenna is suitable for CubeSat structure. A 96mm square antenna substrate is designed and fixed to one of the faces of CubeSat. The design of antenna array is executed using CST software, simulation results shows that antenna has maximum gain 9.6 dB, directivity 10.06 dBi, beam width 54.8° and antenna achieves good impedance matching in the S-band at 2.46 GHz.
