Abstract


The project aims to design a microstrip patch antenna loaded with meta-material using HFSS. The main objective is to enhance the gain and bandwidth of the conventional microstrip patch antenna by more effectively loading the metamaterial. To reduce the size of the antenna, microstrip antenna technologies are miniaturised using high-permittivity dielectric substrates, shorting walls, and shorting pins. However, these methods have the disadvantage of narrow bandwidth and low gain. The new solution for this is to use electromagnetic metamaterials for antenna design. The use of metamaterials not only reduces size but can also improve other parameters, such as bandwidth and gain. A unit-cell Square SRR inserted along both sides of the feed achieves a maximum gain and a wide triple-band frequency range from 12 GHz to 18 GHz (Ku-Band). Ku band is mainly used in satellite communications and radar systems.
