Description

VEHICLE ANTENNA FOR BROADCASTING AND COMMUNICATION}

The present invention relates to a vehicle antenna, and more particularly, to a broadcasting and communication service capable of receiving a combination of signals of a radio frequency band, a TDMB or DABIII frequency band, and an HSDPA, GSM, and WIFI frequency band as a single antenna. It relates to a vehicle antenna.

Vehicles commonly used pole-type helical antennas capable of receiving radios configured inside the vehicle.

Here, the conventional helical antenna is an antenna having a spiral coil-like structure so that resonance can occur at a length shorter than the length of the antenna (λ / 4). Such a helical antenna has resonance at a specific frequency depending on the length and pitch.

However, it is very difficult for the helical antenna to have resonance at another resonance frequency desired by the user as resonance occurs at a specific frequency of a single band.

That is, in the case of the conventional helical antenna, although the first resonance is possible, it is difficult to cause the second and third resonances at a desired frequency, so there is a problem in that two frequencies cannot be selectively received.

In addition, it is difficult to tune and a large error occurs, there are many losses in the return value of the resonance frequency, and the tuning state is deformed when the coil is injected by the insert injection method, so that the desired resonance frequency does not come out. there was.
