Temperature-stable Y2.95Dy0.05MgAl3SiO12 garnet-type 5G millimeter-wave dielectric ceramic resonator antenna
  Temperature stability is a crucial property of microwave electronic components, as well as a pivotal aspect of assessing the performance of microwave dielectric ceramics. In this article, the temperature coefficient of high-Q × f garnet-type Y2.95Dy0.05MgAl3SiO12 microwave ceramic was regulated by doping with different mass ratios of TiO2. Further, combined with the Kramers-Kronig (K–K) formula, the dielectric loss and theoretical permittivity of Y2.95Dy0.05MgAl3SiO12-9 wt%TiO2 ceramic are calculated by infrared reflection spectrum data, which coincide exactly with the experimental results. Importantly, a 5G millimeter-wave antenna was fabricated with Y2.95Dy0.05MgAl3SiO12-9 wt%TiO2 ceramic and tested at 25 °C and 85 °C, respectively. The center frequencies of measurement are 25.99 GHz at 25 °C and 26.12 GHz at 85 °C, and the frequency shift with temperature is rather low, showing excellent temperature stability. The simulated efficiency of 88.5% and gain of 6.05 dBi also indicate that the antenna has favorable radiation characteristics. The results show that the temperature-stable Y2.95Dy0.05MgAl3SiO12-9 wt%TiO2 ceramic antenna has broad prospect in 5G millimeter wave communication.
