“…It is much more difficult to reject a broadband signal rather than a narrow-band signal. The broadband filter may increase the overall dimensions of the rectenna and the insertion loss significantly [17]. Thus a novel approach is developed to integrate the antenna and the filter structures.…”

This paper presents a novel broadband rectenna for ambient wireless energy harvesting over the frequency band from 1.8 to 2.5 GHz. First of all, the characteristics of the ambient radio-frequency energy are studied. The results are then used to aid the design of a new rectenna. A novel two-branch impedance matching circuit is introduced to enhance the performance and efficiency of the rectenna at a relatively low ambient input power level. A novel broadband dual-polarized cross-dipole antenna is proposed which has embedded harmonic rejection property and can reject the 2 nd and 3 rd harmonics to further improve the rectenna efficiency. The measured power sensitivity of this design is down to -35 dBm and the conversion efficiency reaches 55% when the input power to the rectifier is -10 dBm. It is demonstrated that the output power from the proposed rectenna is higher than the other published designs with a similar antenna size under the same ambient condition. The proposed broadband rectenna could be used to power many low-power electronic devices and sensors and found a range of potential applications.

Wireless power transmission was conceptualized nearly a century ago. Certain achievements made to date have made power harvesting a reality, capable of providing alternative sources of energy. This review provides a summ ary of radio frequency (RF) power harvesting technologies in order to serve as a guide for the design of RF energy harvesting units. Since energy harvesting circuits are designed to operate with relatively small voltages and currents, they rely on state-of-the-art electrical technology for obtaining high efficiency. Thus, comprehensive analysis and discussions of various designs and their tradeoffs are included. Finally, recent applications of RF power harvesting are outlined.

“…The polarization of incident waves is difficult to predict in wireless RF power transfer due to the fact that the IoT sensors and devices is arranged randomly by its applications. To solve this problem, various studies on dual polarization have been conducted . A dual circularly polarized rectenna is studied in refs.…”

In this paper, we present a compact dual linear polarized cavity‐backed patch rectenna for optimized wireless RF power transfer with DC power management network. The proposed rectenna is composed of a minimized patch radiator with a backed cavity, the feeding network and a rectifying circuit with DC power management network. The minimized patch radiator with the backed cavity reduces the physical size and enhances the bandwidth. The feeding network is designed to receive all kinds of polarized waves. The rectifying circuit converts received RF energy to DC energy and effectively combines DC energy from each polarization port by DC power management network. The DC power management network also properly operates a load with certain constant voltage. The proposed rectenna is simulated and measured to verify the performance. Each antenna shows about 5.3 dBi peak gain and each rectifying circuit shows about 50% RF to DC conversion efficiency at 0 dBm input power. Due to dual linear polarization, it is observed that received output efficiency is larger than 46% regardless of incident polarization angle.
