Design of a High-Efficiency and -Gain Antenna Using Novel Low-Loss, Temperature-Stable LiTi-(CuNb)O Microwave Dielectric Ceramics.

Microwave dielectric ceramics are vital for filters, dielectric resonators, and dielectric antennas in the 5G era. It was found that the (CuNb) substitution can effectively adjust the TCF (temperature coefficient of resonant frequency) of LiTiO and simultaneously increase its × ( and denote the quality factor and the resonant frequency, respectively) value. Notably, excellent microwave dielectric properties (ε (permittivity) ≈ 18.
