Receiver and antenna incorporated in the receiver |
(57) A receiver, comprising a plurality of antennas is set in a vehicle. Each antenna
comprises a cylindrical bobbin and a dipole helical antenna wound on the bobbin.
The bobbin is made of a synthetic resin and has a certain permittivity. The bobbin
has flanged securing members at both ends and each securing member has a notch. To
secure each antenna to a printed circuit board, built into the receiver, the notch
of the securing member is fitted to the board. In this case, the arrangement of
the antennas is determined in accordance with the electric field intensity and the
electric field vector generated for various receiver setting positions in the vehicle.
