[IEEE 2019 International Conference on Information and Communication Technology Convergence (ICTC) - Jeju Island, Korea (South) (2019.10.16-2019.10.18)] 2019 International Conference on Information and Communication Technology Convergence (ICTC) - Substrate Integrated Waveguide Antenna with Metasurface for Cube Satellites

摘要： In this paper, the substrate integrated waveguide (SIW) slot array antenna using metasurface for cube satellite is operating sandwiched structure arranging a 2 × 5 periodic square conductor patch on the substrate integrated waveguide. As the surface wave excited in the SIW slot array propagates on the metasurface, additional resonance occurred and the impedance matching was better than the conventional antenna. The overall size of the final antenna was 6.75cm × 2.35cm × 0.37cm (1.07λ × 0.37λ × 0.06λ) at 4.74GHz. The simulated results have a bandwidth of 4.73-4.87 GHz (3.38%) satisfying the condition of |S11| < -10 dB. The maximum realization gain is 6.58 dB at 4.76 GHz.
