Advance and Innovation in Wireless Power Transmission Technology for Autonomous Systems

Abstract

This chapter focuses on the concept of transmitting power without using wires that is also known as Wireless Power Transmission (WPT). This chapter attempts to present the most important and relevant works in this field of research in order to develop a topical ‘overview', present the current results, and also share some contributions and ‘vision' for the future. The technological developments in Wireless Power Transmission is also presented and discussed. The advantages, disadvantages, biological impacts and the most potential applications of WPT are also presented. This chapter presents also new and efficient designs of a rectifying antenna (rectenna) involved to be used at low and high input power levels constraints at microwave frequencies of ISM band in particular at 2.45 GHz and 5.8 GHz. The rectennas have been developed were based on microstrip technology incorporating a new class of phased antenna arrays with circular polarization associated with a new RF-to-DC rectifiers.
