The nonlinear ceramics BaZrxTi1-xO3 (x equals 0.3,0.35,0.4,0.45,.05) were investigated. The DC bias field was applied to the samples in order to investigate the dielectric constant behavior of these materials. The effects of temperature and frequency on the dielectric constant and dielectric loss were studied as well. The results show that BaZrxTi1-xO3 (x equals 0.35-0.5) materials have strong nonlinearity. In addition, BaZrTi1-xO3 (x equals 0.35- 0.45) materials have suitable dielectric constant and low dielectric low, higher temperature-stability and better high-frequency properties, so that they can be used as the material of phase shifter for phased- array antennas. A phase shifter was fabricated using BaZr0.35Ti0.65O3 ceramics and phase shift angle of about 66 degree at 2.45GHZ is obtained.
