This book presents the equivalent-circuit parameters for a large number of microwave structures.

This is a professional level, introductory text on antenna principles, design, analysis, and measurements. It is especially suitable for persons who wish to improve their knowledge of antenna principles, concept design, performance analyses, and measurements.

This book covers 'basic designs' in more detail than books that skip important electrical properties and implementation aspects. Numerous additions make the concepts even clearer. New cavity model analysis equations of circular polarization bandwidth, axial ratio bandwidth and power fraction bandwidth have been included.

This book provides a comprehensive introduction and explanation of both the theory and practice of all forms of modern antenna measurements, from their most basic postulates and assumptions to the intricate details of their application in various demanding modern measurement scenarios.

The long awaited revision of the classic book Transmission Line Transformers, by Jerry Sevick, is now in its fifth edition and has been updated and reorganised by Raymond Mack to provide communication engineers with a clear technical presentation of both the theory and practical applications of the transmission of radio communication.Sevick's Transmission Line Transformers: Theory and Practice, 5th Edition reviews the underlying principles that promote a better understanding of transmission line transformers. Ideal for academics and practicing engineers, this edition is divided into two clear parts for easy reference. Part one is a review of the theory and new concepts, including a discussion on the magnetic properties that affect the core of a transmission line transformer. Part two essentially focuses on the 'practice' element of the book title. This section has been updated to reflect the significant changes in component suppliers over the 30 years since the first edition of the book.Highlights of this title include the coverage of substantial background theory, recent work on fractional ratio transformers and high power Balun designs, and provides updated sources for transformer materials to reflect mergers, sales, and business failures over the past 20 years. There is also expanded coverage of commercial sources of low impedance coaxial cable; expanded construction hints for purpose built rectangular parallel transmission lines; plus an updated test equipment chapter to reflect modern computer based experimenter grade test equipment sources. Ray has leveraged his experience with ferrite materials for switching power to explain the performance characteristics of the ferrite materials used for RF power transmission line transformers.

This book combines theory with practical applications for the analysis and design of a wide variety of antenna configurations simulated on FEKO, the leading real-world commercial software programme.

Key Features A fully outlined, systematic and dramatically simplified process of designing equipment to meet EMC requirements. Focuses on simplifications which enable electrical engineers to handle EMC problems. Helps minimize time-to-market of new products and reduces the need for costly and time-consuming modifications. Outlines how to use general purpose test equipment (oscilloscopes and signal generators) can be used to validate and refine any model. Discusses how to used Mathcad or MATLAB to perform analysis and assessment.

This updated edition of the industry's classic text combines the theory, practice, and latest technology of spectrum and network measurements in electronic systems to offer a comprehensive and easy way to understand frequency domain measurements.
