A unique exploration of critical topics in defected ground structures and their applications In Defected Ground Structure (DGS) Based Antennas: Design Physics, Engineering, and Applications, a team of distinguished researchers delivers a comprehensive discussion of key topics related to defected ground structures (DGSs) and their applications to advanced antenna designs, including microstrips, arrays, dielectric resonators, PIFA, and printed monopoles. The book explores major advances in the technology that have occurred since 2006, as well as the fundamentals of the research in the subject. It also presents future possibilities for new researchers to assist in the development of new studies and technologies for practicing engineers and developers. Readers will find concepts, analysis, chronological developments, design physics, and state-of-the-art developments in the field. They will also discover: * A thorough introduction to the concept and evolution of defected ground structure-based antennas * In-depth examinations of defected ground structures for printed antenna feeds * Comprehensive discussions of the use of defected ground structures to control unwanted modes under a microstrip patch for reducing cross-polarized radiation * Enlightening descriptions of defected ground structures used to control mutual coupling in arrays and MIMO designs Perfect for students, researchers, and professionals with an interest in wireless communications, Defected Ground Structure (DGS) Based Antennas: Design Physics, Engineering, and Applications will also earn a place in the libraries of engineers and scientists working in space exploration and defense organizations.
