Studies on Bulk and Thin Films of (Zr,Sn)Ti04 System

Abstract

Rapid growth of the wireless communication industry in recent years has led to a high demand for microwave. ceramic components. Commercial wireless technologies such as cellular phones, direct broadcasting satellite (DBS) and global positioning systems (GPS) have been making rapid progress due to the improved performance of devices like dielectric resonators at microwave frequencies. Dielectric resonators (DRs) are highly densified ceramic bodies of regular geometry which act as resonators at microwave frequencies. They are made of ceramic materials with high dielectric constant (lOr), low value oftano (hence high quality factor, Q value) and low values of temperature coefficient of resonant frequency (~f) . The same materials are also being used for making substrates for microwave integrated circuits (MICs), ceramic filters and low temperature co- fired ceramic (L TCC) based highly miniaturized microwave systems.
