Dielectric Materials for Wireless Communication

Microwave dielectric materials, a terrestrial and satellite communication, GPS, and DBS TV to environmental monitoring via satellite.

A small ceramic component made from a dielectric material. In microwave communications, dielectric resonator filters are used to discriminate between wanted and unwanted signals. When the desired frequency is extracted and detected, it is necessary to maintain a strong signal. For clarity it is also important to change the temperature. In order to meet the requirements of future and future systems. The recent progress in microwave telecommunication, satellite broadcasting and intelligent transport systems (ITS) has resulted in increased demand for Dielectric Resonators (DRs). With the recent revolution in mobile phone and satellite communication systems using microwaves as the propagation of media, the research and development in the field of modern science. In a mobile phone communication, the message is from the phone to the nearest base station. At the heart of the station, the person who is carrying the message, and then the next base station. For such a microwave circuit to work, a part of it needs to be resonate at the specific working frequency. The frequency response component (resonator) used in such a high frequency device. The three important characteristics required for a dielectric resonator are (a) a high quality factor (Qxf) which improves the signal-to-noise ratio, (c) a low temperature coefficient of the resonant frequency which determines the stability of the transmitted frequency.

During the past 25 years, scientists have learned about the materials of known materials. About 5000 papers have been published and more than 1000 patents in the area of dielectric resonators and related technologies. This book brings the best results and experiments in the world over.

The topics covered in the book includes factors affecting the dielectric properties, measurement of dielectric properties, important low loss dielectric material systems dry as perovskites, tungsten bronze type materials, materials in BaO-TiO ₂ system, (Zr, Sn) TiO _{4, the} alumina , rutile, A _n B _n-1 O _3n type materials, LTCC, ceramic-polymer composites etc. The book also has a data table listing all reported low loss dielectric materials with references.

Key Features:

- collects together in a data communication system
- includes tabulated properties of all reported low loss dielectric materials
- in-depth treatment of dielectric resonator materials
