“…Generally, there has been a noteworthy increase in the need of applications in tunable oscillators, filters, phase shifters, and antennas. In these devices, it is desirable to possess high tunability, moderate dielectric constant, and low dielectric loss [1,2]. Barium zirconium titanate (BZT), as an important member of BaTiO 3 -based family, has received extensive interest due to its prominent dielectric performance [3,4].…”
