Abstract
Las telecomunicaciones son una parte importante de nuestro día a día. El desarrollo de
los satélites permite enviar y recibir información desde cualquier lugar del mundo siendo
las antenas esenciales en la transmisión y recepción de esta información. El avance de
la tecnología ha permitido la miniaturización de los componentes lo que permite diseñar
satélites de diferentes tamaños en función de las necesidades. Un ejemplo de ello son los
nanosatélites.
El objetivo de este proyecto es realizar el diseño de una antena transparente que funcione
en banda LoRa y pueda ser adaptada a un nanosatélite CubeSat. Se utiliza la herramienta
CST Studio Suite durante la fase de diseño y simulación de esta. El reto es
diseñar una antena que sea lo más transparente posible permitiendo el paso de luz hacia
la célula solar del CubeSat. El diseño utiliza un diagrama de radiación de la antena
omnidireccional, por lo que se estudia una solución de antena monopolar.
Por último, y con el propósito de comprobar la viabilidad de los diseños, se ha fabricado
la antena diseñada con impresión 3D utilizando filamentos de PLA y Electrifi. El
objetivo de esta fabricación es comprobar la viabilidad del estudio realizado y verificar en
un entorno real los datos obtenidos en las simulaciones.
Telecommunications has become an important tool in our day life.The use of satellites makes it possible to send and receive information all around the world, so that antennas are considered an essential part in the transmission and reception of the information. The miniaturisation of components has been possible due to the advances in technology, what allows designing satellites of different sizes depending on requirements. Nanosatellites are an example of this. This project aims to design a mesh antenna that works in the LoRa band which can be adapted to a CubeSat. The CST Studio Suite tool is used during the design and simulation stage. The challenge is to design an antenna as trasparent as possible which could allow light to pass through to the CubeSat solar cell. The antenna needs to be equipped with an omnidirectional pattern. A monopole antenna is studied, for this purpose. Finally, to test the viability of the designs, the antenna designed with 3D printing has been made up using PLA and Electrifi filaments. This manufacturing aims to check the viability of the study carried out and verify the data obtained in the simulations in a real environment.
