This book covers the theory, modeling, and implementation of different RF energy harvesting systems. RF energy harvesting is the best choice among the existing renewable energy sources, in terms of availability, cost, size, and integration with other systems. The device used for harvesting RF energy is called rectenna. A rectenna can work at the microwave, millimeter-wave, and terahertz waves. It also has the capability to operate at optical frequencies to be used for 6G and beyond communication systems. This book covers all aspects of wireless power transfer (WPT)/wireless energy harvesting (WEH), basics, theoretical concepts, and advanced developments occurring in the field of energy harvesting. It also covers the design theory for different types of antenna, rectifier, and impedance matching circuits used in RF energy harvesting systems. Different future and present applications, such as charging of vehicles, smart medical health care, self-driven e-vehicles, self-sustainable home automation system, and wireless drones, have also been discussed in detail.

Wireless energy harvesting is in high demand these days due to its numerous applications. Understanding energy harvesting methods is essential for real-time applications. “Rectenna” is a device used to energize the low-power systems without using any wired connections. The rectenna or rectifying antenna is also called a wireless battery. Have you ever heard about the concept of wireless electricity? Yes, a rectenna can provide wireless electricity to the home appliances, medical equipment’s in the healthcare centers, electronic systems in the school/colleges, etc. The goal of this book is to give readers an overview and approach to designing harvesting systems. Electromagnetic analysis and a literature review of various harvesting systems are also included in this book.

Our book is divided into five chapters:

The first chapter, “Introduction,” introduces wireless energy harvesting and the device used in this process, known as a “rectenna.” This chapter discusses various types of energy sources that are freely available in the environment. Previously published work and recent developments are also discussed to provide a better understanding of the harvesting system.

The second chapter “Background and Origin of the Rectenna” presents a history of rectenna. It discusses the architecture of the harvesting system. It provides a detailed overview and development of the rectenna. The impact of various energy harvesting applications on human life is also explained.

The third chapter “Antennas” investigates various types of antennas used in energy harvesting systems. The benefits and drawbacks of each antenna type are discussed. The most recent advancements in antenna design are also explained.

The fourth chapter, “Matching Network and Rectifier Circuit,” discusses the importance of the rectifier and impedance matching circuit. This chapter discusses various lumped circuits and distributed circuits, as well as their advantages and drawbacks. The theory and various topologies of rectifier and matching circuits are discussed in depth. The characteristics of the Schottky diode are also discussed.

The fifth chapter, “Rectenna Implementation,” provides an overview of various techniques available for designing a rectenna. Various electromagnetic simulators are discussed for antenna and rectifier circuit implementation. Optimization techniques are also discussed to help readers understand the antenna and rectifier integration.
