Effect of Ni(1–x) CoxMn2O4:0 ? x ? 1 Ceramic Overlay on the Characteristics Ag Thick film Microstripline

Abstract

The effect of Ni_(1–x)Co_xMn₂O₄:0 ? x ? 1 NTC ceramic, in touch overlay on the X and Ku band transmittance and reflectance characteristics of the Ag thick film microstripline is studied. The overlay decreases the transmittance. The decrease in transmittance is a function of the composition of the overlaid material.   The change in phase velocity can be used to predict the dielectric properties of the overlaid material Ceramic material. The composition- dependent effects are observed both in the transmission and reflection mode.
