Manganese zinc ferrite nanopowder was prepared by sol–gel auto combustion method. XRD analysis was carried to estimate the crystal structure and average diameter. Hysteresis behavior of the synthesized nanoparticles was studied with VSM. Composite laminates were prepared to study the microwave absorption properties like permittivity, permeability, and reflection loss in X-band frequency. The laminates were fabricated with epoxy as the matrix containing MnZn ferrite as magnetic fillers in different weight percentages using the hand layup method. Complex permittivities and complex permeabilities were measured using a vector network analyzer in the X-band frequency. Reflection loss of multilayered composite structures was estimated using a MATLAB code developed based on transmission line theory. A maximum reflection loss of −25 dB is obtained for a four-layered structure at 10.2 GHz.
