Multiband Passive Planar RF Circuit Design

Multiband Passive Planar RF Circuit Design delivers essential knowledge and advanced design methodologies of passive RF circuits operating across multiple frequency bands and dynamically adapting to changing system requirements. This text provides a rigorous exploration of core microwave components such as couplers, power dividers, baluns, and phase shifters by covering the theory, design methodologies, as well as practical implementation. Through clear design equations, parameter analysis, and comparative studies, this resource offers a structured approach to high-frequency design and implementation challenges.

The book focuses on cutting-edge techniques for multiband and reconfigurable planar RF circuits, covering dual-band through hexa-band systems. Detailed chapters demonstrate the practical application of stub loading, multisection approaches, defected ground structures, metamaterials, PIN diodes, varactors, and RF MEMS switches. Essential engineering considerations, including fabrication tolerances, de-embedding techniques, and performance optimization, are fully integrated to ensure practical utility in modern adaptive RF architecture.

Engineers, students, and researchers will find this work an invaluable guide to the design trade-offs, advantages, and limitations of next-generation planar RF systems. By combining fundamental principles with state-of-the-art tuning and switching methods, the narrative equips readers to engineer versatile components for contemporary multiband communication standards.
