Materials have a vital effect on satellite communications. Using PTFE (Polytetrafluoroethylene) composite ceramic material, a fractal triangular shape multiband satellite application antenna has presented in this paper. Different kinds of material substrate are used for analysis in the proposed antenna design and depicted their antenna characteristics. The proposed material antenna has attained a bandwidth of 50 MHz, 140 MHz, 145 MHz and 245 MHz at center frequency 5.67 GHz, 6.52 GHz, 7.66 GHz and 8.88 GHz respectively. The design of the proposed antenna is tested in the experimentation. The overall antenna dimension is 0.66λ × 0.75λ × 0.02λ at 5.67 GHz center frequency. In addition, a detailed analysis has been carried out to study the effects of different geometrical parameters on the performance of the antenna by using Finite Element Method based high frequency structural simulator (HFSS)
