Diseño de una antena modelo resonante para banda de onda milimétrica mediante el análisis de parámetros de dispersión

Abstract

This paper present the design of a resonant antenna in the 60 GHz millimeter waveband (mmW), formed by a cylindrical ceramic dielectric, a FR4_EPOXY substrate, a microstrip and ground of cooper. This types of antennas have high efficiency in the GHz band, are compact in size and relatively broad bandwidth with a high degree of design freedom. Several tests were performed on the Ansys HFSS software, where the geometric dimensions and materials were varied with different relative permittivity of the resonant antenna layers in the five proposed designs. The radiant system was determined to operate at a frequency of 60.04 GHz with an S11 parameter of -21.29 dB, a VSWR of 1.49 dB, a directive radiation pattern at 180° at the Phi angle (Φ) with gain of 2.35 dB and a bandwidth of 600 MHz. Under these conditions, the proposed design adapts to the particular needs of this frequency band.
