The aim of this book is to present the modern design principles and analysis of lens antennas. It gives graduates and RF/Microwave professionals the design insights in order to make full use of lens antennas. Why do we want to write a book in lens antennas? Because this topic has not been thoroughly publicized, its importance is underestimated. As antennas play a key role in communication systems, recent development in wireless communications would indeed benefit from the characteristics of lens antennas: low profile, and low cost etc. The major advantages of lens antennas are narrow beamwidth, high gain, low sidelobes and low noise temperature. Their structures can be more compact and weigh less than horn antennas and parabolic antennas. Lens antennas with their quasi-optical characteristics, also have low loss, particularly at near millimeter and submillimeter wavelengths where they have particular advantages. This book systematically conducts advanced and up-to-date treatment of lens antennas.
JOHN THORNTON, PhD, has held research posts at the University of Oxford and the University of York. In 2010, he joined MDA Space and Robotics Ltd to lead their UK antennas program. He has published a number of technical papers, reports, and patent applications, many in the field of antenna engineering.
KAO-CHENG HUANG, PhD, is a Fellow of the Institution of Engineering and Technology (IET) UK, Vice President at the Dharma Academy, and President of the Association of Vijnaptimatrata of China in Taiwan. Dr. Huang is the author of two previous books, including Millimeter Wave Communication Systems (Wiley-IEEE Press), and holds several patents in the area of millimeter wave antennas.
