Abstract

Barium cobalt titanate (BCT) was synthesized using sol-gel method and spin coating technique to produce thin film samples. Different compositions of Ba (1-x)Co (x)TiO 3 were used with x = 0.00, 0.05, 0.10, 0.15 and 0.20. The samples were annealed at 550 °C for lh. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used to characterize the morphological structures of the samples. Based on XRD patterns, the dominant peak has been observed at 2θ = 24.0° and 30.8° with Miller indices (100) and (110) planes, respectively. Based on the AFM analysis, it is shown that the surface roughness of the thin films decreased when composition of x increased. The average dielectric permittivity value of Ba (1-x)Co (x)TiO 3 was obtained approximately ∼15.24. The highest return loss was obtained at -31.4 dB with dielectric permittivity value is 15.28 for sample x = 0.05. The return loss of fabricated antenna decreased with dielectric permittivity value. The bandwidth of the antenna obtained was sufficient for patch antenna application.
