Abstract

Garnet-typed ceramics of Y3Mg1-xMnxAl3SiO12 (0 ≤ x ≤ 0.2) have been synthesized using the traditional solid-state reaction method. The optimal microwave dielectric properties (εr = 10.73, Q׃ = 62,824 GHz, τf = −34.8 ppm/°C) are obtained for Y3Mg0.9Mn0.1Al3SiO12 (x = 0.1) sintered at 1575 °C for 5h. A millimeter-wave dielectric resonator antenna is designed and fabricated using Y3Mg0.9Mn0.1Al3SiO12 as a dielectric unit due to its excellent characteristics of low dielectric constant and high Q׃. The designed DRA resonates at 24.94 GHz with a bandwidth ∼2.20 GHz (S11 < −10 dB). The simulated gain and efficiency are 6.64 dBi and 91.08%, respectively. The results indicate that the Y3Mg0.9Mn0.1Al3SiO12 ceramic has a potential application as an antenna for the 5G/6G millimeter wave frequency band.
