Abstract :
In this paper, we present the study of a printed Vivaldi- type antenna, simulated using two software: “LINpar” to ensure the adaptation of the input of the antenna with the coaxial line and “ANSOFT Designer” for the analysis of the adjusted line and the antenna. This tool has helped us to obtain simulation results in the form of S-parameters and allowed us to obtain a gain of about 10dB, a bandwidth from 500 MHz at 6 GHz and an input impedance of 50 Ohms from the reflection coefficient S11. Finally, to validate the simulations, carried out, the realised antenna has been characterized using a network analyzer. The radiation pattern and S parameter values obtained are very satisfactory.
