Broadband Planar Antennas: Design and Applications

Foreword

With the rapid growth of wireless communications, broadband planar antennas are in strong demand to cover various applications with fewer antennas. This book describes recent advances in broadband planar antennas for wireless phones and LANs. In addition, the book has a unique feature in that it covers the special design requirements for broadband planar antennas in UWB radio systems.

The authors, Dr Zhi Ning Chen and Dr Michael Y. W. Chia, have a lot of computational and experimental experience in the design of these antennas. Dr Chen studied broadband planar antennas at the University of Tsukuba from 1997 to 1999 as a JSPS (Japan Society for the Promotion of Science) Fellow and started to work at the Institute for Infocomm Research with Dr Chia in 1999. Since then we have collaborated closely on broadband antenna research. In 2003, Dr Chen obtained a Doctor of Engineering degree at the University of Tsukuba, the title of his dissertation being Broadband Design of Monopoles in Two-Plate Waveguides and Suspended Plate Antennas. Some of the content of his dissertation is included in this book, and I am greatly honored and happy to write this foreword.

Chapter 1 explains the fundamental antenna indices and the inherent relationships between different types of planar antenna. Chapter 2 covers important features and broadband techniques for microstrip patch antennas. Chapter 3 discusses broadband suspended plate antennas and arrays, which have been studied extensively by the ...
