New application scenarios for dielectric materials in mobile communication systems of the 5th generation — •Roland Gabriel — Kathrein-Werke KG, Anton-Kathrein-Straße 1-3, D-83004 Rosenheim / Germany

The worldwide data volume in mobile communication systems double nearly every year. To address this challenge, higher frequency bands will be used and broadband and multiband equipment are required. The new standard LTE-A and the standardization process for the 5th generation of the mobile communication systems enforces changes in the technology of antennas and filters. Beside the usage of new and higher frequency bands up to 60 GHz the broadband and multiband approach increase the requirements for the linearity of the components. For the use in FDD (frequency division duplexing) - systems this means an extreme low level of the active and passive intermodulation. In this contribution the extendend requirements for passive intermodulation are discussed. Different available solutions for the filter technology will be compared regarding the usage for different system solutions of the 4th and 5th generation. In addition the use of dielectric radiators in antennas will be reconsidered with respect to the multiband approach and the required inter- and intra-band isolation.
