Abstract

PURPOSE:To make it possible to rotate an antenna for FM waves in an arbitrary direction, by forming rotatably a ferrite-coupled dipole antenna. CONSTITUTION:Dipole antenna 8 is fixed onto rotatable disc 1 provided in case 3. Hollow bobbin 2 is fixed to the center back face of disc 1, and coupling coil 7 is equipped around it. The other end of ferrite antenna which has one end fixed to case 3 and has a cylindrical form is inserted to coil 7. Consequently, antenna 8 can be rotated in an arbitrary direction by rotating disc 1. In respect to the connection means between disc 1 and coil 7, the bobbin with coil 7 wound around is fixed, and a contact is used to connect them. Thus, the dipole antenna for FM waves can be adjusted easily to a direction where the maximum electric field can be obtained.
