Abstract :
Design and analysis of a split ring patch antenna on a ceramic material substrate is presented in this paper. The proposed split ring antenna designed and analyzed by using computer aided high frequency electromagnetic solver HFSS. The result shows 170 MHz (7.25 GHz-7.42 GHz) and 173 MHz (8.0 GHz-8.173 GHz) impedance bandwidth with 0.8 dBi and 4.67 dBi gains are achieved at two resonant frequencies 7.32 GHz and 8.07 GHz respectively. The symmetric and almost steady radiation pattern with maximum radiation efficiency of 91% and 94.03% makes the proposed antenna suitable for C and X band satellite application. The input impedance and current distribution of the proposed antenna are also analyzed.
