The utility model discloses a free space wireless energy transmission emit antenna device based on current -shifting, no heat input emitter by a plurality of structures that link to each other throughthe metal column the same, and be the metal helical structure who supports the magnetic dipole mode, the natural frequency of two magnetism resonant cavities of no heat input emitter is the same, therefore has taken place resonance. Produce strong current -shifting through the metal column among two upper and lower metal helical structure to produce the luo rotating magnetic field chang of a non- radiation in the space in the middle of upper and lower two magnetism resonant cavities, thereby become electrical energy conversion alternating magnetic field and be full of whole space. Along withresonating each time, place and have more voltage generation in the receiving coil of the middle optional position of two resonant cavities. Through producing resonance many times, sufficient energywill be gathered in the receiving coil surface, like this receiving terminal received energy in the non - radiation magnetic field here to accomplish magnetic energy to electric transformation of energy, realized the wireless transmission of wide area free space electric energy.
