Energy Optimal Radio Harvester for Multi Sensory System

摘要

In today’s era energy crisis can be minimized by proper alternative head of energy utilization. In today’s smart concepts like smart cities, IOT the most common interference is use of smart technologies with all high level devices in common spectrum. This paper focuses on the same targeted area i.e. common spectrum, which available everywhere and many of times remains unutilized. The basic idea of the paper is to find out the solution of energy crisis from the same of energy utilization. As per the previous work the frequencies used for multiple RFR design are changed in this paper because of the gain of antenna reduces, some frequencies AC power ratio is canceled with another frequency ratio. This paper focuses on Radio frequency harvester unit for multi sensor in reception of multiple frequencies. The total 4 frequencies represent as surfaces of receptors. In which rectified DC output as the output of design. The overall idea about paper is to produce an integral design which will receives 4 frequency bands to produce high AC power gain, furthermore by using power amplifier design or multistage transistor rectifier circuit strong DC power will be obtained. The design uses traditional antenna structure with new design pattern of more gain radiating RFR faces design. The HFSS software used for processing on parameters. FR4 and RT/Duroid is used with εr=4.4, εr= 2.2 respectively. Due to this design at higher frequencies we get the gain in 8.7 dB and 8.9dB. This paper focuses the design of 2 frequencies surfaces and mathematical analysis of another 2 frequencies. Thus whole complete model can be used as Integrated RFR model for energy solutions.
