| Résumé : |
This paper describes attenuation measurement using the modified microstrip line technique from new microwave substrate material. The magnitudes of the transmission coefficient (S21) from the microstrip measurement were used to determine the attenuation of the ZnO/PCL nanocomposites substrate with respect to different percentages of ZnO nanoparticles filler. Result from the measurement showed amongst others that as the filler content increases, the attenuation increases. The highest magnitude for attenuation was calculated for the 70% ZnO nano filler with a value of 14.92 dB and the least attenuation was calculated for the 25% ZnO nano filler, which value gave 6.72 dB which is very good for shielding applications. Transmission electron microscope (TEM) was used to analyse the average particle size of the ZnO powder used as filler in the study. The analysis showed that the average particle size was 52.7 nm. |
