A variety of novel applications in the millimeter-wave frequency range have been developed in the last few years: for example, wireless LAN at 60 GHz, automotive radars at 77 GHz, and imaging systems at 94 GHz. The development of these applications has stimulated the implementation of a wide range of novel components and circuits operating at millimeter-wave frequencies. Both industry and academia have devoted significant effort to the development of novel technologies and efficient integration techniques, with the aim of improving the quality of millimeter-wave systems, decreasing their cost and improving their reliability. This book provides comprehensive coverage of all aspects relating to components, circuits and system integration at millimeter wave level. The book is divided into four parts: technologies for passive components; technologies and materials for active devices and circuits; complete system integration strategies; and major millimeter-wave applications. For the first time, this book offers a broad view on various mm-wave applications and advanced technologies with their relative merits, to optimize device selection, system integration and packaging for high-performance, low-cost systems. Each chapter is authored by recognized academic and industrial authorities in the field of advanced devices, components and system integration at mm-wave frequency. The book covers a wide range of technologies and topologies, evaluating their merits and offering guidance on component selection, circuit design and system integration. It describes in detail the most important mm-wave applications and design of application-specific systems.
