Latest research and applications of analytical models and designs of phased array antennas and systems Phased Array Antennas presents precise analytical models and designs of phased array antennas and systems in a logical and comprehensive manner starting from fundamental principles of phased array radiation. Numerous relevant and practical design examples and detailed derivations of theorems and concepts are included to make the book as self-contained as possible. This new edition includes information on recent developments in the phased array arena published in journals and conference proceedings, a chapter devoted to metamaterial analysis from fundamental principles of electromagnetism, and the most updated phased array structures and beam formers. The book is divided into three sections. The first section is mostly devoted to the development of the Floquet model-based approach for infinite and finite phased arrays. This section begins with an introduction of the traditional approach and its drawbacks. The second section presents applications of the Floquet modal analysis to important phased array structures. The third section covers several important aspects of a phased array design including array tolerance analysis. Phased Array Antennas includes information on sample topics such as: Scan characteristics of a pencil beam array in light of gain, grating lobe, beam-width beam squint, and mitigation of beam-squint issueScan characteristics of array-fed confocal reflectorsThe relationship between a Floquet mode and observable array parameters such as active element pattern, mutual coupling, scan blindnessGeneralized Scattering Matrix (GSM) approach to analyze multilayer array structures, including stacked patches, ring-slot radiators, FSS and screen polarizersFinite array modeling including the edge effects on input match and radiation patternCharacteristics of step and multi-flared horns for enhanced radiation efficiencyFrequency selective surfaces, meander line polarizer screens, printed reflect-array antennas, metamaterial and their fundamental propertiesBeam formers, beam shaping algorithms, array system analysis and array tolerance analysis Phased Array Antennas is an excellent reference for advanced graduate students who are seeking professional careers in antenna and microwave engineering as well as antenna design engineers and technical consultants seeking to understand and apply the latest Floquet model for analyzing practical phased array structures.
