Abstract

The changes in the characteristics of microstrip rejection filter and simple microstriplines due to bulk and thin film dielectric overlay are reported in this paper. Al2O3 overlay both bulk and thin film increases theQ of the filter. All other overlays decrease theQ. TiO2 thin film shows improvement inQ whereas with bulk TiO2 the filtering property is not observed. The effect of overlays on simple lines is to reduce the transmission without much effect in the reflection.
