Abstract

This project purpose is to investigate and design the circular polarization patch antenna at 2.45 GHz.The development is based on circular polarization for microstrip patch antenna.Microstrip patch antenna is used because it provides light in weight and low cost suitable with the small antenna types other than the use of this technology in several decades.Then,the antenna is design using the CST software and fabricated at FR-4 board with dielectric substrate of 4.3 with the height of 1.6 mm. The antenna consists of square patch,truncated at corner and notch.The performances of the antenna will be measure regarding the parameter characteristics suitable with the performances of the design.Regarding the polarization, circular polarization is obtained when two orthogonal modes are equally excited with 90° phase difference between them.This is due to the resulting wave having an angular variation.Here,the projects have been done by simulation and measurement.The design was start by done the simulation in order to gain resonant frequency at 2.45 GHz with dimension of the patch first,then proceed by fabrication process and finally the measurement test was obtain through the fabricated patch antenna.Lastly the comparison have been made between simulation and measured results.
