Utilization TV broadcasting electromagnetic waves frequency to produce electric energy through transfer power without cable

Electromagnetic wave radiation is an extremely important and has long been a telecommunications research experts. But in nature there are a lot of electromagnetic source of free that has not been used for the benefit of further. On paper was devised a system called ambient electromagnetic harvesting. The system is aimed to catch a source of free in the electromagnetic waves from the transmitter uhf (tv) to a later tillable and used as a source of alternative energy. A device that takes in these systems among others are antennæ accepter and power harvester. Antennæ accepter made is a log periodic dipole array, serves to receives electromagnetic waves and turn it into an electrical signal fire. Being power harvester serves to change an electrical signal ac of antennæ be dc and fastens it. For location near the source of transmitter sctv (tv) obtained maximum tension 1766 mv. If the measurement of being done in our free (the lab b.301) the maximum voltage is produced by 591 mv. Obtained from various experiments that closer to the station and the more stable condition of equipment, the bigger the voltage is produced. With arus produced range from 0.008 ma it is expected that this system is able to distribute battery with 600 mah specifications, 1.2 v for 21 hours.
