The given paper presents research of the energetic characteristics of three-phase rectenna’s element which receives and transforms custom electromagnetic fields to the direct current. Rectenna’s element is formed from a system of three emitters, symmetrical vibrators which are interchanged. Input filters were connected to internal terminals of vibrators the first, second and third single-phase rectifier circuits respectively. Obtained simulation results of the three-phase rectenna’s element showed the advantage of its energy characteristics in comparison with single-phase rectification schemes.
