In this work, the conventional mixed oxide process was used to form Ba(Zn1/3Nb2/3)O3-chopped strands composites. The singlephase compound with the chemical equation Ba(Zn1/3Nb2/3)O3 was generated after sintering at 1250 °C for 4 h. Varied amountsof Ba(Zn1/3Nb2/3)O3-chopped strands were fabricated for the structural examination. X-ray diffraction (XRD), energydispersiveX-ray spectroscopy (EDS) and scanning electron microscopy (SEM) were carried out for the structural analysis, andthe results showed that the second phase did not form in Ba(Zn1/3Nb2/3)O3. In addition to, the Ba(Zn1/3Nb2/3)O3-strandscomposites were created by hot pressing using the compositions of Ba(Zn1/3Nb2/3)O3-chopped strands in various rates andepoxy. The Ba(Zn1/3Nb2/3)O3-chopped strands compound created in varied weights, and epoxy powder were utilized tomanufacture microwave shielding effect composites. Using a two-port vector network analyser (VNA) device, the microwaveshielding effect of Ba(Zn1/3Nb2/3)O3-chopped strands composites was examined in a range of 0-8 GHz. A minimal of -44.75 dBshielding effectiveness value was reached at 6.24 GHz and 1.4 mm in thick. The Ba(Zn1/3Nb2/3)O3-chopped strands werefabricated as composite and their properties were defined characterized for shielding effectiveness. To modify microwaveshielding effectiveness, the content of components in the specimens may be adjusted for the wider and required frequencyranges.
