Abstract

This thesis is focused on the design of Antipodal Vivaldi antenna (APVA) by compared the performance of the Ultra Wideband antenna (UWB) using two type of material which is graphene and copper as the patch of the antenna. The parameters to be improved in this thesis are included reflection coefficient (S11), gain, radiation pattern, realized gain and directivity of the antenna. The results of the performances of APVA are only covered by the simulation of the design using CST Studio Suite Software. Two APVA with different materials are designed using CST software with the ranges of operating frequency between 1 to 15 GHz. The change in performances between the two types of material will be discussed in this thesis. From the simulation results, the value of return loss is achieving the aim which to be less than -10 dB, as both graphene and copper based APVA obtain the S11 with the value of -25.704 dB and -25.535 dB respectively. The gain of the APVA is 4.915 dB (graphene) and 4.882 dB (copper) which also achieving the goals of more than 4.5 dB gain to be achieved. Besides that, both of the antennas are radiate at directional radiation pattern with the value of the realized gain of 4.903 dB for graphene and 4.870 dB for copper based APVA. The value of directivity is 5.882 dBi is recorded via simulation for both materials used in the design of APVA. At the end of the project, an optimized APVA are design with the respected desired results.
