{x = 0.025, 0.05} compositions synthesized using conventional mixed oxide route were investigated in the Ku-band. For the measurement of these properties, vector network analyzer was used. The relative permittivity (ɛ
r
) of synthesized compositions ranged from 4.12 to 18.98 and loss tangent (tan δ) ranged from 0.0012 to 0.93. Composition with x = 0.025 exhibited shielding effectiveness SE > 10 dB with a bandwidth of 1.8 GHz and composition with x = 0.05 exhibited SE > 10 dB with a bandwidth of 1.9 GHz. The present compositions are proposed as electromagnetic interference (EMI) shields in the Ku-band.
