Diseño y simulación en banda X de una agrupación de antenas de ranuras con su red de alimentación utilizando tecnología SIW: diseño y simulación en banda X de una red de alimentación de 1:4 formada por divisores de potencia de 1:2 utilizando tecnología SIW.

Abstract

In this curriculum integration work, we will implement a power network of one input port with four output ports, which will be formed from 1:2 power dividers. The operating band to be worked is the X-band corresponding to a frequency range from 8.2 GHz to 12.4 GHz. Chapter 1.- Information and definitions corresponding to the classical rectangular waveguide, as well as the substrate integrated waveguide (SIW) are given. Mathematical formulas are proposed in order to obtain the values of its dimensions for subsequent modeling. Chapter 2.- Based on the equations presented in Chapter 1, the construction of the classic rectangular waveguide filled with dielectric and the SIW waveguide is carried out, in order to demonstrate that their performance characteristics are very similar. The implementation of the 1:2 power splitter will be followed by the design of the arms to connect the output ports of the input splitter to the output splitters to form the power network with SIW technology. Chapter 3.- With the structure modeled in 3D we proceed to obtain the results using the electromagnetic simulation software. The results will be optimized in terms of the level of adaptation, insertion and return losses, using the dispersion parameters. The main variations to be made in terms of optimization are in the structure of the 1:2 power divider and in the arms (elbows) that connect the power dividers to the output, which allow the power network to be formed. This will be done in separate parts due to the high computational cost that this simulation requires. The results obtained will be compared with each other in order to achieve a good bandwidth level and a good adaptation. The results, conclusions obtained and recommendations to be considered are included in the graphs.
