Abstract

Abstract: Garnet-typed ceramics of Y3 Mg1- x Mn x Al3 SiO12 (0 ≤ x ≤ 0.2) have been synthesized using the traditional solid-state reaction method. The optimal microwave dielectric properties ( ε r = 10.73, Q׃ = 62, 824 GHz, τ f = −34.8 ppm/°C) are obtained for Y3 Mg0.9 Mn0.1 Al3 SiO12 ( x = 0.1) sintered at 1575 °C for 5h. A millimeter-wave dielectric resonator antenna is designed and fabricated using Y3 Mg0.9 Mn0.1 Al3 SiO12 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 (S 11 < −10 dB). The simulated gain and efficiency are 6.64 dBi and 91.08%, respectively. The results indicate that the Y3 Mg0.9 Mn0.1 Al3 SiO12 ceramic has a potential application as an antenna for the 5G/6G millimeter wave frequency band.
