• Format: ePub

Produktbeschreibung

Comprehensive text on the fundamentals of systematic design methods and analysis for slow-wave substrate integrated waveguide

Enriched with practical examples and illustrations, Slow-Wave Substrate-Integrated Waveguides introduces the application of slow-wave substrate-integrated waveguides in miniaturized and integrated antennas. The book details the advantages of microstrip lines and metal waveguides, with low cost, low loss, and easy-to-integrate with planar circuits, delves into slow wave structure in the design of antennas and devices, allowing for additional distributed capacitors and inductors, and discusses how to overcome the technical challenges associated with miniaturizing slow wave microwave devices and antennas.

Topics explored in this book include:

• The potential for larger multi-beam antennas to improve communication system capacity
• Devices such as couplers, miniaturized phase shifters, and waveguide cross-junctions
• Antennas such as bidirectionally-fed slow-wave substrate-integrated waveguide monopulse slot array antennas and miniaturized H-plane horn antennas with -30 dB sidelobes
• Transmission lines, beamforming networks, and future perspectives in the field

Slow-Wave Substrate-Integrated Waveguides is an essential reference for students and professionals in the fields of physics, optics, electromagnetics, communications seeking to improve the spectrum efficiency, energy efficiency, and cost efficiency of wireless communication systems.
