RF and Microwave Engineering

RF and Microwave Engineering: Fundamentals of Wireless Communications, 4th Edition, provides a physical-technical textbook for studying high-frequency technology. Author Frank Gustrau establishes core principles governing electromagnetic and voltage waves, laying a theoretical foundation in transmission line theory and signal behavior across wireless communication systems.

The text explores passive circuits, waveguides, and high-frequency components across distinct operational settings. Technical sections investigate scattering parameters alongside radio wave propagation and antenna structures. Throughout these topics, physical-technical fundamentals pair with numerical simulations and software design examples to demonstrate how electromagnetic concepts apply to real-world component analysis.

This textbook aligns with upper-level academic instruction for undergraduate students and graduate students in engineering programs. Its clear progression from wave physics to software design examples also provides early-stage RF practitioners and practicing engineers with an accessible reference for modern high-frequency design methods.
