Conception, modélisation et optimisation des antennes imprimées reconfigurable pour les systèmes de communication sans fil

Abstract

This thesis focuses on the study and design of a miniaturized and frequency-reconfigurable printed antenna. Using CST Studio Suite software, a patch-type structure was optimized through the introduction of slots and notches in order to reduce its dimensions while maintaining a fundamental resonant frequency of 2.4 GHz. The integration of PIN diodes as switching elements enables dynamic reconfiguration of the antenna across different frequency bands, particularly those used by Wi-Fi, LTE, and 5G standards. The obtained results highlight a compact, efficient, and adaptable solution that meets the growing requirements of modern telecommunication systems.
