ii ABSTRACT DESIGN AND IMPLEMENTATION OF RF TO DC CONVERTER FOR LOW POWER IOT DEVICE BASED ON RF ENERGY HARVESTING TECHNOLOGY By Azka Zharfan Hafizh NIM: 13218051 (Bachelor’s Program in Electrical Engineering) Nowadays, most IoT devices use batteries to operate. The use of batteries will certainly increase the amount of battery waste in the environment when the energy stored in the battery is run out/ cannot be recharged. Battery waste can pollute the surrounding environment which dangerous for other organism, because batteries are made of hazardous chemicals. There are several alternative energy sources that can be used to obtain energy through the energy harvesting process, one of them is energy derived from RF signals. Based on the description above, a system is made to operate low power IoT device using RF energy harvesting technology. RF energy harvesting is a method used to obtain energy sources from radio frequency signals. Radio frequency signals in the form of electromagnetic waves are converted into electricity that can be used in various low power IoT devices. RF energy harvesting using a rectenna which consists of a rectifier and an antena. The antena used to receive RF signals and the rectifier is used to convert RF signal into DC voltage. One alternative to store the energy from harvester is a supercapacitor. This bachelor thesis describes the design and implementation process of an RF-DC converter circuit with a Dickson single stage multiplier type in order to obtain a minimum DC voltage of 3.3V that can be used to operate low power IoT device.
