Abstract
A small antenna for vehicle comprises a coil member of helical antenna structure with a plurality of coils formed; a connector disposed at one end of the coil member; a signal pin contacting with the connector; a cylindrical member coupled to the other end of the coil member and made of metal material; a dielectric body inserted inside the coil member and cylindrical member and disposed adjacent to the connector and signal pin; a conductor inserted inside the coil member and cylindrical member and disposed at one end of the dielectric body; and a cover member enclosing the coil member and cylindrical member inside which the dielectric body and conductor are inserted.
Claims5
A small antenna for vehicle, comprising:
- a coil member of helical antenna structure with a plurality of coils formed;
- a connector disposed at one end of the coil member;
- a signal pin contacting with the connector;
- a cylindrical member coupled to the other end of the coil member and made of metal material;
- a dielectric body inserted inside the coil member and cylindrical member and disposed adjacent to the connector and signal pin;
- a conductor inserted inside the coil member and cylindrical member and disposed at one end of the dielectric body;
- and
- a cover member enclosing the coil member and cylindrical member inside which the dielectric body and conductor are inserted,
- wherein the cover member has a length of 110˜130 mm, a frequency of radio band is received through the dielectric body, coil member and cylindrical member, a frequency of TDMB(Terrestrial Digital Multimedia Broadcasting) or DAB (Digital Audio Broadcasting Band ) band is received by means of resonance due to coupling phenomenon of the dielectric body and conductor, and the signal pin receives frequency of band for mobile communication.
