This research focus on the study of the characteristics of antenna using metamaterial
concept. The reasons that metamaterial is chosen are to miniaturize the size of
antenna and increase the performance in return loss and gain. The focus of this project
is to study on the best structure for antenna application. The design and simulation of
different metamaterial structure is carried out using CST software. The performance
of antenna is studied by interpreting the return loss, gain and radiation pattern
generated from simulation. As a result, the highest return loss is given by Split Ring
Resonator structure (SRR) which made up from silver with -34.6300 dB in range of
frequency of 7 GHz to 18 GHz. For the gain, it is the Symmetrical structure which
made up form silver that has the highest value which is 5.570 dB compare to SRR with
4.447 dB within the same frequency range.
