Abstract

In this thesis, the performance of Vivaldi antenna are studied based on the two different materials that build up the antenna that is graphene and copper. Performance of the Vivaldi antenna is investigated by parametric study to get the optimized design based on the return loss response. The results of performance of Vivaldi antenna are only cover the simulation and the simulations are using CST Studio Suite software. Two Vivaldi antennas are design for the operating frequency range from 8 to 12 GHz frequency band with return loss better than 10 dB. These two antennas are design based on parametric study result. Both antennas are used microstrip to slotline transition feeding. This antenna is constructed using FR4 substrate which has dielectric constant ∈r 4.30 and graphene and copper material which is has 0.508mm and 0.035mm thickness. The parameter of antenna such as gain, directivity, efficiency and return loss are discussed.
