DUAL-BAND MULTI-PORT RECTENNA FOR RF ENERGY HARVESTING

A dual-band RF energy harvesting circuit using 4th order dual-band matching network

A novel compact rectifier for dual-band operation in the RF energy harvesting is presented. The circuit comprises a 4th order dual-band impedance matching and a single-series circuit with one double diode, both are integrating into a compact shape to occupy a small area of 30 × 35 mm. The merit of the proposed rectifier circuit is that it can be extended to n number of the frequency band by usi...

A Dual-band Rf Energy Harvesting Using Frequency Limited Dual-band Impedance Matching

Abstract—In this paper, a novel dual-band RF-harvesting RF-DC converter with a frequency limited impedance matching network (M/N) is proposed. The proposed RF-DC converter consists of a dual-band impedance matching network, a rectifier circuit with villard structure, a wideband harmonic suppression low-pass filter (LPF), and a termination load. The proposed dual-band M/N can match two receiving...

Multi-band RF Energy and Spectrum Harvesting in Cognitive Radio Networks

Energy harvesting (EH) from Radio Frequency (RF) sources is considered a promising solution for future wireless technologies in terms of efficiency and battery lifetime, specially for applications that do not consume a lot of energy such as Internet of Things (IoT) devices. This paper investigates a multiband EH schemes under cognitive radio interweave framework. All secondary users are conside...

Vivaldi Antenna for RF Energy Harvesting

Energy harvesting is a future technology for capturing ambient energy from the environment to be recycled to feed low-power devices. A planar antipodal Vivaldi antenna is presented for gathering energy from GSM, WLAN, UMTS and related applications. The designed antenna has the potential to be used in energy harvesting systems. Moreover, the antenna is suitable for UWB applications, because it o...
