System for wireless power transfer

The issues of wireless power transfer over short distances are considered. approach may be used for charging batteries in unmanned vehicles. It is proposed to use the technique microstrip structures transfer. form a directional coupler on symmetrical strip lines when approaching by front parts. length interaction chosen several times longer than quarter wavelength. Ballast resistors excluded from circuit. This leads small losses distance between changes wide range. Modeling operation system has been carried out, an experimental sample made and studies have out. simulation experiment well accorded.
