Abstract:
This project proposes a new generation of antenna that applies metamaterial as a base construction. The current bulky size of antennas can easily be replaced by the newlyinvented metamaterial. The simulation results show that an antenna with a metamaterial substrate has improved size and return loss, while an antenna with a metamaterial cover has improved propagation directivity. A combination of two materials, RT5880 and Perfect Electric Conductor, in omega structures is able to produce the metamaterial features. An investigation of the S-parameters has been carried out to determine the negative permittivity of the metamaterial. The return loss from the simulated results meets the minimum specification of the -10-dB cutoff. Meanwhile, the radiation directivity of conventional antennas can be improved significantly with the usage of a metamaterial slab as a cover. The novel antenna is able to take advantage of technology to be smaller in size but better in performance.
