Produktbeschreibung

Comprehensive resource describing both fundamentals and practical industry applications of antennas and radio propagation employed in modern wireless communication systems

The newly revised and thoroughly updated Third Edition of this classic and popular text, Antennas and Propagation for Wireless Communication Systems addresses fundamentals and practical applications of antennas and radio propagation commonly used in modern wireless communication systems, from the basic electromagnetic principles to the characteristics of the technology employed in the most recent systems deployed, with an outlook of forthcoming developments in the field.

Core topics include 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, femtocells, picocells, megacells, and narrowband and wideband channel modelling with the effect of the channel on communication system performance.

Worked examples and specific assignments for students are presented throughout the text (with a solutions manual available for course tutors), with a dedicated website containing online calculators and additional resources, plus details of simple measurements that students can perform with off-the-shelf equipment, such as their laptops and a Wi-Fi card.

This Third Edition of Antennas and Propagation for Wireless Communication Systems has been thoroughly revised and updated, expanding on and adding brand new coverage of sample topics such as:

• Maxwell's equations and EM theory, multiple reflections as propagation mechanisms, and waveguiding
• HAPS (High Altitude Platforms) propagation, design and noise considerations of earth stations, macrocell models, and cellular base station site engineering
• FSS (frequency selective surfaces), adaptive antenna theory developments (massive and distributed MIMO in particular), and how to process raw data related to channel measurements for mobile radio systems
• The techniques used in mobile systems spanning the latest 4G, 5G and 6G technology generations
• A wider range of frequencies, extending from HF, VHF and UHF up to the latest millimetre wave and sub terahertz bands

With comprehensive coverage of foundational subject matter as well as major recent advancements in the field, Antennas and Propagation for Wireless Communication Systems is an essential resource for undergraduate and postgraduate students, researchers, and industry engineers in related disciplines.
