Written by a renowned expert in the field, this book presents the fundamentals of phased array systems, including contemporary and advanced methods. It features applications ranging from advanced and commercial radars to remote sensing, and multiple channel communications. You will find detailed coverage of fields and waves analysis, domain analysis, fundamentals of array theory, far field synthesis, Floquet theory, aperture weighting functions, impedance and mutual coupling theory, and many other technical applications in system design. The book helps you understand array fundamentals that can be realized by analog, digital or hybrid beamforming methods, reflecting perceived trends in the industry. You’ll also benefit from numerous practice cases, with examples and illustrations to sharpen your understanding. The book leads readers through practical observations, analysis, and design methods that equip both entry-level and experienced engineers with the basic information to solve today’s problems and be in position to take on next-generation engineering and scientific challenges.

Array Antennas: Phased array systems have become a natural development path, originating in the microwave design of passive antennas. There are multiple examples of constrained feed systems, such as those formed from TEM and waveguide transmission lines, power dividers, and delay circuits. These designs generally use a single Tx source or receiver but have migrated to distributed systems with multiple sources and receivers. These in turn have progressed to digitally beamformed systems using multiple digital-to-analog converters (DACs) and analog-to-digital converters (ADCs). The next generation of devices seek more general applicability in low cost, size, weight, and power (C-SWAP) designs.

Throughout these progressive steps, the intrinsic phased array value has remained consistent, offering the degrees of freedom in the domains of space, frequency time, and polarization. So, while there are many possible design adaptations to the technology, the focus of our studies into phased arrays relies on the fundamentals and limiting factors, with a few examples for illustration and practical application.
