<a href="GAMAT, MATHEW P. and PORAL, MA. LYCA L. Radio Frequency Harvesting System for Smartphones Surfing through Mobile Data in 3G and 4G Band. Undergraduate Design Project. Bachelor of Science in Electrical Engineering. Cavite State University-Cavite College of Arts and Trades, Rosario, Cavite. June 2019. Adviser: Engr. Dexter S. Ramos. Technical critic: Prof Noelle T. Legaspi. <br/><br/>The study was conducted from December 2018 to May 2019 in order to design a radio frequency harvesting system unit that would receive these waves, convert into electricity, and store them. Specifically, the project aimed to: I) design and construct three (3) antennae suitable for harvesting radio frequency (3G & 4G band) ranging between: 1800 :MH.z-1900 MHz, 1900 MHz-2000 MHz, and 2000 MHz-2100 MHz; 2) design and construct the RF-DC converter circuit; and 3) test and evaluate the technical performance of the system in terms of open circuit voltage, energy harvested versus data consumed, charging rate of the supercapacitor, and power output. A pair-T test was used in analysis to determine if there is a significant difference between the results of using different range of patch antenna while mobile data surfing in 3G and 4G band. <br/><br/>It was found out the RF power coming from smartphones surfing the net through mobile data can be harvested and converted into DC power. However, the voltage was found to be very unstable and of low value, having an average open circuit voltage of 35.39mV. Also, the average power measured from the device was 2:40 mW, which was not yet practical to be used as power source for electronic devices. Further study was recommended to properly harness this power into usable form. The study costs of P 9,765.00.">GAMAT, MATHEW P. and PORAL, MA. LYCA L.
