Ceramic compositions for 5G devices containing niobium: A survey

Abstract

The main dielectric properties of several ceramic materials having niobium in their composition, proposed to take part in 5G telecommunication devices, are reviewed. A preliminary basic presentation of 5G systems, the requirements for implementing their use, a concise review of the ceramic compositions containing niobium that have been studied thus far, and an evaluation of their performance are detailed. A survey is presented, including more than 80 different compositions containing niobium, focusing on key parameters, such as dielectric constant, quality factor, temperature coefficient, and sintering temperature. These parameters play a role for assessing the potential application of these ceramics in 5G devices.

Temperature-stable Li4Ti3O8 composite microwave dielectric ceramics and their applications in dielectric resonator antennas

“…Dielectric resonant antennas (DRAs) have attracted significant attention due to their various characteristics, including high integration, lightweight, low loss, diverse material types, and simple manufacturing techniques. 23 Consequently, a DRA was prepared using Li 4 Ti 3 O 8 ( ε DR = 26.7) and using Rogers RT5880 ( ε r = 2.2, tan δ = 0.0009) as the substrate for the antenna. A simulation was performed with a high-frequency structure simulator (HFSS).…”
