Planar Antennas for Wireless Communications

Kin-Lu Wong
Wiley Interscience
301 pages; $89.95
ISBN: 0-471-26611-6

With the advent of cellular communication systems and wireless local area networks, planar antennas with low profile, such as microstrip and other printed antennas, have been receiving a lot of attention. Many researchers, including the author and his graduate students, have reported their designs in journal articles and conference papers. The intent of this book is to organize and present these advanced designs in the area of planar antennas for wireless communications.


The book is organized into seven chapters. Chapter 1 presents an introduction and overview of recent advances in planar antenna designs for wireless communications. In Chapter 2, novel planar inverted-F antenna (PIFA) designs using slotted patch, meander patch, folded patch spiral strip, two or more shorted patches and parasitic shorted patch loading are described to achieve dual- or triple-frequency operation. Chapter 3 discusses very low profile monopole design for dual-band or multi-band internal mobile phone antennas. Chapter 4 presents recent advances in base station antenna designs for GSM, DCS, PCS and UMTS cellular communication systems. Many advanced designs reported recently are described in detail and experimental results of the constructed prototypes for single-band, dual-band and multi-band operation are presented. Chapter 5 is devoted to the planar antenna designs for WLAN and Bluetooth applications. Designs suitable for WLAN base stations capable of circular polarization radiation and dual-band operation are presented. Examples of surface-mountable antennas such as the ceramic chip antenna, FR4 chip antenna and strip monopole wrapped into a rectangular-disc-like structure are also described. Among other types of planar antennas, dielectric resonator (DR) antennas are attractive for their low loss, compact size and good performance at higher frequencies, and their promising designs for wireless communications are addressed in Chapter 6. Chapter 7 is devoted to the integration of antennas for different operating bands, for example two separate GPS and DCS antennas or two separate DCS and WLAN antennas. This book is a very useful reference on mobile and WLAN antennas for scientists and engineers.

Microwave Circuit Modeling Using Electromagnetic Field Simulation

Daniel G. Swanson, Jr. and Wolfgang J.R. Hoefer
Artech House Inc.
469 pages; $125, £87
ISBN: 1-58053-308-6

This book is about modeling microwave circuits using commercially available electromagnetic field solvers. Before a circuit can be modeled, it is necessary to understand how the tools work. All the field solvers discussed are based on well-established numerical methods for solving Maxwell's equations. Enough background material on the major numerical methods is offered to help the reader appreciate what is going on behind the surface. A lot of effort is spent outlining the strengths and weaknesses of each numerical method in a fair and balanced way. This knowledge will help in choosing the right software tool for a specific task and set up the problem more intelligently. Design case studies make up about half of the material in this book. The examples are not intended to be a complete design procedure for any particular component. Rather, they are intended to demonstrate the trade-offs and compromises that must be made to get an efficient solution.

This book is unique in the way it broaches the subject of electromagnetic simulators, not from the inside out, beginning perhaps with an extensive theoretical development and culminating in an algorithmic implementation. Rather, the reader is invited to discover and experience an extensive arsenal of modeling and simulation features from the perspective of microwave practitioners, building on their traditional design experience, their knowledge of laboratory practices and their intuitive understanding of microwave components and systems. The extensive use of case studies reveal the primary target audience of this book, namely designers and practicing engineers. However, the focus on practical design applications will also be invaluable to students, researchers and educators who use electromagnetic simulators for demonstration, analysis and physical insight. The book also offers three appendices giving a survey of commercially available field solver software, a list of software vendors and some Internet sites relevant to the field.
