The paper is devoted to the development of the energy harvesting system of microwave range. The block diagram of the system was developed and stands for measuring antenna patterns and study of the transmission voltage dependence from distance were made. To perform the study were selected six types of antennas: dipole, wire dipole, stripline, horn, parabolic and stripline antenna array. The study revealed that the parabolic antenna has the advantage in distance of energy transfer out of the six considered antennas. The achieved value of the potential on the receiving device is about 23 mV at the distance of 9 m. The obtained results allow realizing the energy harvesting system in a small industrial premise or room.
