Abstract

PURPOSE:To enable to receive sharp picture less in ghost remarkably, by constituting antenna wound with wave conduction coil to the magnetic amplifier element providing diamagnetic substance in the magnetic field made by the magnetic substance. CONSTITUTION:The antenna is constituted by winding the wave conduction coil 2 on the magnetic amplifying element 1 providing the diamagnetic substance 12 in the magnetic field made from the magnetic substance 11. The electromagnetic waves received with this antenna are weak current to excite the amplifying element 1 flowing to the coil 2 and very high transmission and reception power is obtained. Thus, sharp picture very low in ghost can be obtained.
