| dc.description.abstract | Innovation along with the times is increasing, one of which is about efficient and
environmentally friendly technology. These technologies such as the utilization of wind,
water, heat, electromagnetic waves and others into electrical energy is called energy
harvesting. Electromagnetic signal waves are widely used as the main communication
medium in this time, because there are many electromagnetic signals in free air. Over
time, a lot of research to be able to take advantage of electromagnetic signals. The
research yielded results in which electromagnetic signals are alternative energy that can
be converted into electrical energy or also known as energy harvesting. The technology is
called rectenna (rectifier antenna) which functions to convert electromagnetic signal
waves into electricity with direct current. The purpose of making this thesis is to make a
prototype that can convert electromagnetic signal waves into electrical energy using a
rectifier circuit combined with a television antenna. In this final project, a prototype
energy harvesting system is designed using a rectifier circuit using method voltage
doubler 10-stage with a schottky diode MBRB20100CT and capacitor 100 pF as well as
television antenna yagi-uda. In testing the energy harvesting system prototype that was
carried out, the largest output reached 1.565 V in the form of a DC voltage. So that the
application of the system is intended for equipment that requires a low power supply such
as mini sensors and indicator lights. | en_US |
