The development of context-aware environments and applications requires a strong connectivity, which calls for new spectral bands and radio resource management functionalities in both current 5G and future 6G wireless communication systems. This presents challenges in implementing wireless transceivers and radiating systems in terms of device integration, miniaturization, and element isolation. This study proposes high-performance miniature devices using metamaterial-inspired complementary resonators, which demonstrate excellent agreement between analytical circuit models and electromagnetic simulations. The design flexibility allows for easy tunability and frequency scalability. However, the presented devices are just a fraction of the potential combinations for integration in future wireless communication systems.
The advent of context-aware environments and related applications demands a high degree of connectivity, with new spectral bands and related radio resource management functionalities in the current 5G bands and foreseen in future 6G wireless communication systems. This, in turn, poses new challenges in the implementation of wireless transceivers and radiating systems, in terms of device integration, miniaturization and element isolation, among others. High-performance miniature devices are presented and studied in this work, aided by metamaterial-inspired complementary resonators. A single particle is used to build a single layer, double layer, double frequency resonators and power dividers. A complete characterization of each equivalent circuit is also analyzed, showing great agreement between analytical circuit models and full-wave electromagnetic simulations. By adding more particles, different diplexers and triplexers in the multi-layer configuration are proposed. The flexibility in the design is the key advantage, as all devices are easily tunable and the output lines can be built in different layers, enabling frequency scalability from RF to millimeter wave ranges. Nevertheless, they are only a sample of all possible combinations of devices that can be designed for integration in future wireless communication systems.
