چکیده انگلیسی
A new kind of antenna using high permittivity dielectric materials as the substrate was designed. Its size is 34 mm Ã 34 mm in square and 1 mm in height. The operating frequency of the array is designed as 3.5 GHz with the bandwidth of 50 MHz at â10 dB attenuation. BiNbO4 ceramic substituted by a little amount of V2O5 was chosen as the substrate materials. Bulk ceramics were sintered at 890 °C for 2 h and processed into slices samples. The antenna was made on the substrate by screen-printing technology and the properties were measured using a 8720ES network analyzer. The test results show that 3.07 GHz centre frequency and 34 MHz bandwidth at â10 dB attenuation have been obtained.
