In this paper, the Ku-band rectangular microstrip patch antenna (RMPA) is intended to operate in the dual-band for satellite communication (SATCOM). The antenna which is obtained for dual-band by utilizing a U-slot and vertical slits on RMPA is fed with a microstrip feed-line for the input impedance of 50 ohms. Arlon AD 300 which is used as the dielectric substrate for the antenna has the permittivity value of 3, the loss tangent value of 0.003 and the thickness of 1.524 mm. The antenna has the return loss of -30.078 dB at 12.25 GHz (the first resonance center frequency) and -31.214 dB at 14.24 GHz (the second resonance center frequency). Voltage standing wave ratio is 1.0647 at 12.25 GHz and 1.0566 at 14.24 GHz. The results reveal that the bandwidths (BW) of 836 MHz (11.894 to 12.73 GHz) at 12.25 GHz for downlink and 703 MHz (13.823 to 14.526 GHz) at 14.24 GHz for uplink are achieved. The Ku-band RMPA which is designed and simulated via Computer Simulation Technology Microwave Studio (CST MWS) is convenient for dual-band SATCOM systems.
