Diseño del desplazador de fase activo de una antena inteligente para redes Wi-Fi en entornos rurales.

Abstract

The present work exposes the design of a quadrature active phase shifter for an intelligent antenna at the 2.4GHz frequency. The basic principles of the phase arrangements on which this design is based are described, as well as the characteristics of the intelligent antennas, the basics of the phase shifters and the power dividers and directional couplers. The modules of the quadrature hybrid coupler, the lines of microwells and a Wilkinson power combiner and variable gain amplifier that conform it and meet the design restrictions fixed for a frequency of 2.4GHz are designed and designed and a displacer is designed of phase in quadrature. The results of the simulations carried out with the professional Microwave Office program that corroborate the validity of the design are shown, demonstrating that the phase shift reached by this design is 90.3 °, a value very close to the theoretically expected 90 °.
