This paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves. Whilst free space is undoubtedly a known medium for wireless energy harvesting, space waves are too attenuated to support realistic transmission of wireless energy. A layer of thin stratified dielectric material suspended in mid-air can form a substantially less attenuated pathway,...
This paper presents a multi-band fractal antenna designed for RF energy harvesting. The antenna is based on a general cross-dipole antenna. By adding iterated slot on each pole, a widely multi-band performance is achieved. Size and iteration time of the antenna are optimized via simulation on HFSS, and as a result the antenna covers most of the common RF resources such as 3G, 4G and WLAN in 2.4 GHz...
