Diseño de una antena plana compacta para banda de onda milimétrica

Abstract

This article describes the design of a compact broadband flat antenna with millimeter wave frequency at 60 GHz, consisting of a T-shaped strip with bronze as a component printed on a Rogers Ro4350 (tm) substrate, and a T-shaped strip connected ground plane of tin material. Several tests and optimizations were implemented in Ansys HFSS software, changing the geometric dimensions and configuring materials with different relative permittivity in each of the layers of the resonant antenna, obtaining five designs that satisfactorily meet the desired requirements. Based on the results obtained, it was determined that the most optimal radiant system operates at a frequency of 60.00 GHz with an S11 parameter of -22.9920 dB, a VSWR of 1.2330 dB, a bandwidth of 2.54 MHz and a gain of 4.24 dB. Under these conditions there are conclusions about how the dispersion parameters such as radiation pattern, bandwidth and gain, can change according to the modifications made in the 5 proposed designs.
