Effect of Ni(1-x)CoxMn2O4: 0≤x≤1 NTC Ceramic overlay on Ag Thick film ring resonator
Negative coefficient thermistor material of composition Ni(1-x)CoxMn2O4: 0≤x≤1 was prepared by low temperature, chemical route. The effect of Ni(1-x)CoxMn2O4: 0≤x≤1 NTC Ceramic in touch overlay on Ag Thick film microstrip ring resonator is studied. The overlay improves the electromagnetic coupling, increasing peak transmission and decreases in the resonance frequency are observed. The change in resonance frequency of the microstrip ring resonator is used to the predict effective dielectric constant of the multilayer structure. The composition-dependent effects are observed.
