The properties of nickel zinc ferrite (Ni0·5Zn0·5Fe2O4) thick film with Ni0·5Zn0·5Fe2O4 nanopowders as active powders and linseed oil as the organic vehicle is studied and investigated in this work. Ni0.5Zn0.5Fe2O4 thick film paste samples have been prepared with various weight ratios to study the rheology properties of the pastes. Rheology results show that paste with 30% wt. Ni0.5Zn0.5Fe2O4 has suitable rheological shear-thinning behavior, which is required for formulating screen printing pastes. Dielectric and magnetic properties of the thick film show values lower than bulk Ni0·5Zn0·5Fe2O4, which is relatable to the weight ratio of the ferrite in thick film and thickness of approximately 20 μm. With a low firing temperature of 200 °C, a screen printed microstrip patch antenna with a Ni0·5Zn0·5Fe2O4 thick film layer as substrate overlay has an increase in return loss by 64.22% and also increase in bandwidth by 84.61%, which has shown great potential for microwave devices applications.
