This book addresses the design challenges in near-field wireless
power transfer (WPT) systems, such as high efficiency, compact
size, and long transmission range. It presents new low-profile
designs for the TX/RX structures using different shapes of defected
ground structures (DGS) like (H, semi-H, and spiral-strips DGS).
Most near-field WPT systems depend on magnetic resonant coupling
(MRC) using 3-D wire loops or helical antennas, which are often
bulky. This, in turn, poses technical difficulties in their
application in small electronic devices and biomedical implants. To
obtain compact structures, printed spiral coils (PSCs) have
recently emerged as a candidate for low-profile WPT systems.
However, most of the MRC WPT systems that use PSCs have limitations
in the maximum achievable efficiency due to the feeding method.
Inductive feeding constrains the geometric dimensions of the main
transmitting (TX)/receiving (RX) resonators, which do not achieve
the maximum achievable unloaded quality factor. This book will be
of interest to researchers and professionals working on WPT-related
problems.
