Abstract

Disclosed is a resonant type power transmission antenna device provided with a plurality of transmission antennas 12 and a plurality of reception antennas 13 , the resonant type power transmission antenna device including a transmission shield antenna 22 arranged between the plurality of transmission antennas 12 , a reception shield antenna 23 arranged between the plurality of reception antennas 13 , transmission and reception circuits 21 and 24 to operate the transmission and reception shield antennas 22 and 23 in electromagnetic field resonance having a phase opposite to that of the transmission and reception antennas 12 and 13 respectively adjacent to the transmission and reception shield antennas.

Claims (12)

1. A wireless power transmission device comprising:

a power transmission antenna that transmits electric power;

a power reception antenna that receives electric power from said power transmission antenna and supplies received electric power to a load equipment; and

a shield antenna that generates electromagnetic fields having a phase opposite to said power transmission antenna and said power reception antenna,

wherein said power transmission antenna is arranged inside a transmission side of said shield antenna; and

said power reception antenna is arranged inside a reception side of said shield antenna.

2. The wireless power transmission device according to claim 1 , wherein said power reception antenna is arranged inside said power transmission antenna, and

a reception side of said shield antenna is arranged inside a transmission side of said shield antenna.

3. The wireless power transmission device according to claim 2 , wherein a reception side of said shield antenna dose not supply electric power from a transmission side of said shield antenna to said load equipment.

4. The wireless power transmission device according to claim 2 , further comprising a shielding member disposed outside a transmission side of said shield antenna.

5. The wireless power transmission device according to claim 1 , wherein a reception side of said shield antenna dose not supply electric power from a transmission side of said shield antenna to said load equipment.

6. The wireless power transmission device according to claim 1 , further comprising shielding members disposed outside a transmission and a reception side of said shield antenna.
