Abstract
En este proyecto de fin de grado se presenta el diseño de una antena multifrecuencia en banda C (en las frecuencias 3.91 GHz y 6.117 GHz) con polarización circular para alimentación de reflectores.
En un primer modelo, se diseñan dos bocinas aisladas, de modo que cada una cumpla con las especificaciones dentro de su banda correspondiente. Dentro de este modelo podemos encontrar el diseño de las bocinas con y sin polarización circular y las simulaciones con el reflector.
El segundo modelo consiste en combinar las dos bocinas mediante una guía coaxial, con lo que conseguimos una antena capaz de funcionar en dos bandas de frecuencia. Como en el caso anterior, se muestran las extensiones de la polarización circular y del reflector.
In this Bachelor's Thesis it is introduced the design of a multi frequency C-band (at frequencies 3.91 GHz and 6.117 GHz) with circular polarization antenna for feeding reflectors. In a first model, we design two isolated horns, so each one achieves the requirements inside its own band. In this model we will find the design with and without circular polarization and the simulations with the reflector. The second model consists in mixing both horns with a coaxial waveguide, so we get an antenna able to work in two frequency bands. As in the previous step, we show the extensions of circular polarization and the reflector.
