Análisis comparativo de los parámetros de dispersión de una antena tipo patch dipolo media onda y antena tipo hilo dipolo media onda en la frecuencia de resonancia de 60Ghz

Abstract

This paper details a comprehensive comparative study between an airborne half-wave dipole antenna and a patch antenna with a half-wave dipole patch, operating at 60 GHz. Theoretical values are calculated for both antennas and modeled using HFSS ANSYS software. The design measurements of each antenna are adjusted to tune them to the target frequency and optimize scattering parameters such as S11, VSWR, impedance, gain and radiation pattern. In addition, the impact of the conductor material on frequency, scattering parameters and gain when changing antenna conductors is analyzed. The results show that, in the half-wave dipole antenna, by increasing the air space between the arms and the radius of the dipoles, the magnetic coupling is reduced and interference or unwanted energy transfer is reduced. Likewise, by increasing the radius of the dipoles, the radiating surface is increased, emitting more energy, reducing reflections and improving the VSWR, since there is a 233.33% difference with respect to the theoretical value, equivalent to an increase of 0.88 units. On the other hand, in the half-wave microstrip dipole antenna, varying the width, length and height of the dipoles influences the operating frequency, also changing the height of the substrate directly affects the bandwidth of the antenna, because as it increases by 128.47% equivalent to 0.37 units, the bandwidth of the antenna increases proportionally.
