Dispositivos pasivos en bandas de microondas utilizando estructuras periódicas : Diseño y simulación de un acoplador direccional utilizando la tecnología Groove Gap Waveguide (GGW), en la banda de microondas.

Abstract

With the constant growth of technology, there is a need to increase bandwidth, which leads to the design of devices that operate at high frequencies. Traditional technologies do not meet these requirements, in addition to the fact that manufacturing processes are difficult due to the tiny size of the designs. The "Groove Gap Waveguide" technology is presented as a possible solution to these scenarios, which makes possible the construction of devices for high frequencies, besides presenting low losses, because it does not need a good contact between their surfaces thanks to the use of periodic structures that act as walls for the propagated fields, as well as a similar operation to the rectangular waveguides. This work shows the procedure performed to design and simulate a Riblet coupler in GGWVP technology working in the X-band, within which the analysis of its dimensions that will facilitate future designs is highlighted, as well as establishing the appropriate number of pins for the coupling area of the coupler. Finally, a comparison between the designs and a commercial coupler is made.
