Implementación de un banco de acopladores dinámico de impedancia en tecnología MICRSOTRIP para antenas

Abstract

In the present work, the design, simulation and implementation of a bank of dynamic impedance couplers in microstrip technology for monopole, single dipole, double dipole and patch antennas with linear and arbitrary polarization is developed, on a previously characterized economic FR4 substrate.

The first chapter presents the most used impedance coupling methodologies, as well as the theoretical review of the transformation of complex impedances using transmission lines.

In the second chapter, the characterization of the FR4 substrate is carried out, the coupler designs are proceeded by Keysight ® ADS simulation tool. Next, a theoretical analysis is developed with the MATLAB computational tool of the dynamism of the designed coupling networks based on the maximum referential value of 10 dB of reflection loss.

The third chapter describes the implementation of the different impedance couplers. In the same way, the parameters S11 and S21 simulated and measured by a vector network analyzer are presented.

Chapter four presents the conclusions and recommendations obtained because of the work.

CST simulations are supported by external project PIE-DETRI-PUCE-2019.
