وصف الكتاب | 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. |
المراجعة التحريرية | The book will be of interest to most device implanters as it does offer some useful tips that can be applied to conventional adult practice, in addition to explaining how to implant in patients with congenital heart disease. (Cardiology News, October - November 2007)"This is a concise guide...that uses an easy to navigate format. It makes excellent use of tables, drawings, and clinical vignettes..."
