Diseño de una antena multimodo sobre substrato textil para aplicaciones corporales

Abstract

[ES] En esta tesis se presenta una antena textil multimodo para redes de área corporal inalámbricas. La antena propuesta puede ser integrada fácilmente en la ropa debido a su flexibilidad. Su comportamiento multimodo ayuda a reducir la atenuación originada en entornos NLOS (Non Line of Sight) y propagación multicamino.

[EN] A textile antenna designed for Zigbee Wireless Body Area Network (WBAN) is presented. The antenna is based on a capacitive loaded metallic circular ring that exhibits multimode characteristic at 2.4 GHz. The multimode behaviour is obtained using four feeding ports excited with specific phase configurations. The proposed antenna can be easily integrated into clothing due to its thickness and flexibility. Furthermore, its multimode behaviour helps to reduce the attenuation originated by NLOS (Non Line of Sight) environments and multipath propagation. The performance of the multimode antenna is similar to a MIMO system, but using a single antenna, so the space necessary in human body is minimized. For this reason, the multimode antenna is the best solution for WBAN applications.
