Radio-frequency (RF) energy harvesting (RFEH) and radiative wireless power transfer
(WPT) have attracted significant interest as methods of enabling battery-free sustainable …

Power beaming is the efficient point-to-point transfer of electrical energy across free space
by a directive electromagnetic beam. This paper clarifies the basic principles of power …

Abstract 5G has been designed for blazing fast and low-latency communications. To do so,
mm-wave frequencies were adopted and allowed unprecedently high radiated power …

Overcoming the challenge of battery recharging and replacement in industry Internet-of-
Things (IoT) applications is considered by proposing the design of a triple-band high-gain …

A compact and broadband rectifying antenna (rectenna) which consists of a novel slotted
antenna and an efficient rectifying circuit is presented for wireless power transfer at LTE …

Ambient electromagnetic and RF energy is an ubiquitous energy resource that is found
everywhere but difficult to harvest because of the time-varying orientation of incoming …

The concept of long-range microwave power transmission (MPT) has been driven by the
desire to remotely power satellites, drones, or some mobile facilities. The advantage of long …

It is difficult to effectively rectify or convert low power in the circuit stage of harvesters. The
high-gain antenna can offer a higher level of power and is beneficial to RF power harvesting …
