Abstract
The project purpose is to design and develop the circular polarization patch antenna with the presence of air layer substrate at 2.45 GHz. The development is based on circular polarization for patch antenna focus on reader RFID application at 2.45 GHz. However, with the presence of air layer substrate, it able to wider the bandwidth so several application in area of 2.45 GHz also should be considered. Patch antenna is used because it provides light weight and low cost suitable with the small antenna types other than the used of this technology is already for several decades. Then, the antenna is design through the CST software and fabricated at the FR-4 board. The performance of the antenna will be measure regarding the parameter characteristics suitable with the performance of the design. Regarding the polarization, circular polarization is obtained when two orthogonal modes are equally excited with 90° phase difference between them. Here, the project have been done by simulation and measurement. The design was start by done the simulation in order to gain resonance frequency or center frequency at 2.45 GHz with the dimension of patch that characterizes first. Then, when the simulation results gave the targeted results, so it proceeded by fabrication process and finally the measurement test was obtain through the fabricated patch antenna. Next, the comparison have been made between the simulation and measurement results.
