Abstract

Effect of DC biasing field on dielectric properties of (Ba0.6Sr0.4)TiO3 and ZrO2-doped (Ba0.6Sr0.4)TiO3 for application in phased array antennas have been characterized. The grain size is maximum for (Ba0.6Sr0.4)TiO3 doped with 0.5 wt% ZrO2 content. The real part of the relative dielectric constant of the specimens decrease with increasing applied DC biasing field. The tangent loss of the specimens is influenced much less by the DC biasing field than the real part of the relative dielectric constant. The tunability of the real part of the relative dielectric constant is about 45% for (Ba0.6Sr0.4)TiO3 doped with 0.5 wt% ZrO2 content.
