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...
متن کاملDesign and Implementation of Microstrip Antenna for RF Energy Harvesting
This paper describes the antenna design for RF power harvesting system. The design goes through three phases designing of antenna, matching network and rectifier. A dual band Microstrip antenna suspended above ground plane is designed to operate in GSM 1.8 and ISM 2.4 GHz bands. The antenna incorporates the capacitive feed strip which is fed by coaxial probe technique where the inductive impeda...
متن کاملTransmission Power and Antenna Allocation for Energy-Efficient RF Energy Harvesting Networks with Massive MIMO
The optimum transmission strategy for maximizing energy efficiency (EE) of a multi-user massive multiple-input multiple-output (MIMO) system in radio frequency energy harvesting networks is investigated. We focus on dynamic time-switching (TS) antennas, to avoid the practical problems of power-splitting antennas, such as complex architectures, power loss and signal distortion when splitting the...
متن کاملCompact Patch Antenna Design for Outdoor Rf Energy Harvesting in Wireless Sensor Networks
In this paper, two compact patch antenna designs for a new application — outdoor RF energy harvesting in powering a wireless soil sensor network — are presented. The first design is a low-profile folded shorted patch antenna (FSPA), with a small ground plane and wide impedance bandwidth. The second design is a novel FSPA structure with four pairs of slot embedded into its ground plane. Performa...
متن کاملAnalysis and Design of High Gain NRI Superstrate Based Antenna for RF Energy Harvesting System
A high gain patch antenna inspired by 4 layers of negative refractive index (NRI) metamaterial (MTM) superstrate is proposed to operate at downlink radio frequency (RF) band (935MHz to 960MHz) of GSM 900). The MTM unit cell consists of a nested split ring resonator (SRR) on one side and strip line laminated on other side of FR4 substrate. The effective permeability and permittivityof the unit c...
