Low‐Loss Microwave Dielectrics in the (Mg1−xZnx)2TiO4 Ceramics

Abstract: The microwave dielectric properties and the microstructures of (Mg1−xZnx)2TiO4 ceramics prepared by the conventional solid‐state route were investigated. Lattice parameters were also measured for samples with different x. As x increased from 0 to 0.05, the Q×f of the specimen can be promoted from 150 000 GHz to a maximum 275 300 GHz. It also showed a remarkable lowering in the sintering temperature (∼100°C). Ilmenite‐structured (Mg0.95Zn0.05)TiO3 was detected as a second phase. The coexistence of the second ph… Show more

“…As the carrier frequency of interest in communication systems is being extended to a higher frequency regime, it has been driving the need for new materials with an extremely low dielectric loss (high quality factor, Q) in the last few years [1,2]. Although materials having extremely low dielectric loss have been reported for high frequency applications, research on new microwave dielectrics is still ongoing and has become a primary issue recently [3][4][5][6][7][8].…”

“…Several research efforts have recently been dedicated toward the development of such dielectric materials [1][2][3][4][5]. In addition, a high Q × f is also required [6,7] to simultaneously retain a small return loss and achieve a wide bandwidth of the GPS antennas for practical applications.…”

“…However, high quality factor has been playing a more prominent role recently because of the raise of carrier frequency in the communication systems [1,4]. Consequently, the search on new high-Q dielectric materials, such as the MgO-TiO 2 binary system, has brought much more attention in the last few years [5][6][7][8][9][10][11]. In particular, MgTiO 3 and Mg 2 TiO 4 are both recognized as good candidates for high frequency applications [5][6][7][8][9][10][11].…”
