本书是最新的2007年版本,个人认为是一本写的非常好的书,对于无线通信的天线与传播介绍得很全面和详尽,适合从事天线设计和无线通信行业的工作者阅读。非常幸运,这是高清晰的电子版。发电子书,对我来说还是第一次,所以很高兴能把这本书分享给大家,希望大家在分享和交流中共同进步。
Antennas and propagation are of fundamental importance to the coverage, capacity and quality of all wireless communication systems. This book provides a solid grounding in antennas and propagation, covering terrestrial and satellite radio systems in both mobile and fixed contexts. Building on the highly successful first edition, this fully updated text features significant new material and brand new exercises and supplementary materials to support course tutors. A vital source of information for practising and aspiring wireless communication engineers as well as for students at postgraduate and senior undergraduate levels, this book provides a fundamental grounding in the principles of antennas and propagation without excessive recourse to mathematics. It also equips the reader with practical prediction techniques for the design and analysis of a very wide range of common wireless communication systems.
Including:
- Overview of the fundamental electromagnetic principles underlying propagation and antennas.
- Basic concepts of antennas and their application to specific wireless systems.
- Propagation measurement, modelling and prediction for fixed links, macrocells, microcells, picocells and megacells
- Narrowband and wideband channel modelling and the effect of the channel on communication system performance.
- Methods that overcome and transform channel impairments to enhance performance using diversity, adaptive antennas and equalisers.
