“…Some designs in such as [20] and [21] using an antenna-filter structure have embedded the harmonic-rejection property on the receiving antenna to replace a filter. Additionally, in order to handle the instability of ambient incident signals, the potential of utilizing an adaptive rectifier to match the dynamic input power level were discussed in [22] and [23]. Some researchers have conducted the field measurement survey in order to identify the frequency band and the power density of the ambient wireless energy [24], [25].…”

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.

Inductively wireless power transmission technology is a new technology which uses electromagnetic reso nance induction principle to transport energy within a certain distance. This paper studies principle and characteristics of inductively wireless power transmission and inductively wireless power transmission technology, making a comparison by collecting a variety of data and taking software simulation. Compared with the traditional wired power transmission technology, inductively wireless power transmission technology is more flexible, secure and reliable, and can achleve power transmission within medium distance between powered equipments and power equipments. This technology pro posed in this paper has the advantages of non-directional and strong penetrating, etc.

“…This structure offers the best compromise between DC output voltage level and conversion efficiency at those low incident power levels [10]. Furthermore, zero bias Schottky diodes are often used in this case due to their low threshold voltage (around 150 mV) and their low junction capacitance (0.18 pF) [11].…”

Abstract-In this paper, an autonomous low voltage and ultralow power DC-DC converter is presented. This novel topology is inspired from the classical Armstrong oscillator structure. In addition to be self-powered and autonomous, this converter is suitable for high-impedance sources. Theoretical and simulationbased optimizations are used in order to design the converter. A fabricated prototype is tested. It harvests RF energy from a low power rectenna (rectifying antenna). High output voltage and good performances are achieved in the range of 4µW to 1mW of input power.
