To transmit satellite data with a large capacity to ground stations can be overcome by increasing the bandwidth. DGS (defected ground structure) method can increase the antenna bandwidth and has a miniaturization effect making it suitable for satellite application design. The antenna has been designed with circular polarization to overcome polarization loss. DGS pattern with dual-slot X-shaped is used. DGS dimensions such as slot length, slot width, and distance between DGS slots are optimized using CST software. The antenna was designed by using Roger 5880 and Roger 4350 substrate to obtain a miniaturization effect and wider beamwidth. Measurements on Roger 4350 substrate obtained a bandwidth of 97MHz or 4.3%, Gain 3.63dB at frequency of 2220MHz and beamwidth of 90 degrees. Measurement of the antenna with Roger 5880 substrate bandwidth obtained 92MHz or 4.1%. The antenna gain is 5.85dB at 2220MHz frequency and 85 degrees of beamwidth. Antenna with Roger 4350 substrate has a miniaturization effect of 35.3% on Roger 5880 substrate. Antenna with the use of DGS on Roger 4350 obtained reduction effect is 4.8% and the Roger 5880 substrate obtained reduction effect 1.84%. The results obtained indicate that the DGS method with an X-shaped dual-slot pattern can reduce the antenna size and increase the antenna bandwidth.
