UWB, miniaturized and directive metamaterial loaded antenna for satellite applications
Antenna parameter optimization using S-shaped metamaterial embedded in antenna substrate at high frequency (THz) is elucidated in this paper. Upon incorporation of proposed metamaterials’ array inside the antenna substrate, bandwidth of antenna increases by 770 GHz and directivity by about 11%. Results obtained are well in coherence between FEM based Ansoft HFSS simulation and Matlab programming based on CAD formulas using equivalent circuit analysis of patch antenna. A low frequency (scaled) prototype of the proposed structure is fabricated and nearly 15% deviation is obtained in comparison with the simulation results.
