Characterization of a Circular Polarization Microstrip Antenna using a Temporal Method

In this paper, we describe the determination of the characteristics of a very complex circular polarization microstrip antenna using a temporal method. In fact, the entire simulated structure integrates the radiating element and the phase shifter which allows to generate a circular polarization. The main characteristics such as axial ratio, deviation angle of the polarization ellipse are proposed. To validate the simulation, a comparison between the numerical and experimental results is performed. However, the differences between the experience and the simulation can be reduced by improving the spatial discretization of the antenna. Unfortunately, the excessive memory space and time computation of this simulation technique does not allow this. So we propose, at the end of this article that the association of, this simulation technique and the determination of the temporal Green´s functions will allow the increased complexity of the studied structure by modelling the various elements which make up the antenna.
