Rectifier Using UFO Microstrip Antenna as Electromagnetic Energy Harvester

Rectifier antenna is an antenna that is integrated with a rectifier circuit that has the ability to convert RF waves into DC voltage. Microstrip antenna on the rectenna can serve as capture electromagnetic waves is then converted into AC waveform that will by rectifier will be recycled again into a DC waveform. Recycling concept can be applied electromagnetic waves at a frequency of 16500–2700 MHz, which is then the frequency will be altered to produce a DC waveform that can be measured into a voltage. Of order to make a rectenna is capable of working at a frequency of 1650–2700 MHz, it is necessary to design a microstrip antenna and a rectifier circuit that is able to work at that frequency. Microstrip antenna design dimensions obtained through calculation optimization and simulation. This microstrip antenna fabrication using materials a Phenolic White Paper - FR4 with a dielectric constant (εr) = 3.9.
