Broadband and high-efficiency of garnet-typed ceramic dielectric resonator antenna for 5G/6G communication application

Garnet-typed ceramics of Y3Mg1-xMnxAl3SiO12 (0 <= x <= 0.2) have been synthesized using the traditional solidstate reaction method. The optimal microwave dielectric properties (epsilon(r) = 10.73, Qxf = 62,824 GHz, tau(f) = -34.8 ppm/degrees C) are obtained for Y3Mg0.9Mn0.1Al3SiO12 (x = 0.1) sintered at 1575 degrees 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 Qxf. The designed DRA resonates at 24.94 GHz with a bandwidth similar to 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 Y3Mg0.9Mn0.1Al3SiO12 ceramic has a potential application as an antenna for the 5G/6G millimeter wave frequency band.
