SUN / MICROWAVE ENERGY HARVESTING RESOURCE INITIATIVE (SUNEHRI)The industrial development <strong>and</strong> population increase has created an enormous increasein the global dem<strong>and</strong> for energy. SUNEHRI (SUN Energy Harvesting ResourceInitiative) is a work for renewable energy. It aims to produce electricity fromsun/microwave energy, create cooling systems that can cool down buildings withoutelectricity consumption, eliminate electricity shortfall <strong>and</strong> provide a green solution withno waste products.In this era <strong>of</strong> energy crisis <strong>of</strong> the country, misery increases due to usage <strong>of</strong> electrical<strong>and</strong> electronic home appliances, which provide comfort while putting heavy burden onthe utility budget. Effective <strong>and</strong> cheap ways <strong>of</strong> power generation are the need <strong>of</strong> thehour. There are abundant radiations with high energy in them, available in theatmosphere, mostly originating from the sun <strong>and</strong> few available due to manmademicrowave sources i.e. Radios, mobiles, satellites. After detailed research <strong>and</strong> availablenano technologies, Infrared has been considered to be most suitable to create coolingeffect <strong>and</strong> to generate electricity in aid with microwaves. The principle aim <strong>of</strong> the projectis to resolve the energy crisis <strong>and</strong> reduce country‘s dependency on oil by making heatabsorbing IR surfaces <strong>and</strong> converting Microwave energy to DC power using antennatechnology with the improved efficiency <strong>and</strong> relatively less expensive level.The project comprises <strong>of</strong> two parts; the first part focuses on capturing abundantmicrowave on an ultra wide b<strong>and</strong> (UWB) antenna array <strong>and</strong> capturing IR (heat) b<strong>and</strong> <strong>of</strong>solar spectrum on nano UWB terahertz antennas arrays. The collected heat radiationswould reduce the temperature <strong>of</strong> the surroundings, thus resulting in cooling effectwithout consuming electricity. The second part involves converting the receivedmicrowave energy into minor home usage electricity through rectification methods. Thisis done by combining the output <strong>of</strong> UWB Microwave antenna arrays by UWB WilkinsonPower Combiner designed in the range 1-13 GHz <strong>and</strong> then rectifying their combinedoutput using Schottky diodes to get DC as an output.A prototype UWB antenna array <strong>and</strong> power combiner has been designed, simulated,fabricated <strong>and</strong> tested which is capable <strong>of</strong> capturing microwave energy from 1-30 GHz.Syndicate Members: Ali AnjumJawad KhalidSidrah JavedMehreen RehmanSupervisor:Dr Naveed Iqbal15
