Study and Characterization of New Topologies of Dielectric Resonator Antennas: Application to New Wireless Communications Systems

Nowadays, we are witnessing a considerable change in the field of telecommunications, be it mobile telephony, wired or wireless networks. Advances in the fields of information technology, communication, microelectronics and telecommunications have led to a massive deployment of new networks which today connect a mass of individuals and computing entities. These networks are the backbone of all services influencing both the personal and professional spheres, with almost instant access to information, social networks and the IT world. In this regard, the antennas deployed in new telecommunications systems must be able to adapt to such an environment in perpetual evolution. Indeed, with the emergence of new telecommunications standards such as the Internet of Things (IoT), new telecommunications systems must meet new requirements, including the ability to include a large number of features to meet to the growing needs of users, such as making several standards coexist on the same compact structure, reducing interference with neighboring devices, improving the transmission rate, avoiding phenomena of antenna performance degradation in the presence of external disturbance and ensuring good efficiency in receiving data. Agile antennas in radiation patterns also present themselves as potential candidates to meet the requirements imposed.
