Abstract

Disclosed is a vehicular antenna. The antenna, according to an embodiment of the present invention, comprises: a spring part which is perpendicularly disposed on the roof of a vehicle; and a metal part perpendicularly disposed on the top of the spring part. The metal part comprises: a first part extending from the body; a second part which extends from the body and is disposed to have a predetermined interval from the first part; and a third part which extends from the body, is disposed between the first and second parts, and is bent to form a predetermined angle with the first and second parts.

Claims

1. A vehicular antenna, comprising:

a spring part vertically arranged on a roof of a vehicle; and

a metal part vertically arranged at an upper surface of the spring part, wherein

the metal part includes;

a first part formed by being extended from a first body;

a second part formed by being extended from the first body to be spaced apart from the first part at a predetermined distance; and

a third part formed by being extended from the first body to be interposed between the first part and the second part and formed by being so bent as to form a predetermined angle with the first and second parts.

2. The vehicular antenna of claim 1, further comprising a magnetic substance part at a bottom surface of the metal part.

3. The vehicular antenna of claim 1, further comprising a power supply part supplying a current by being disposed at a bottom surface of the spring part, and a transmission part transmitting the current by being interposed between the spring part and the metal part.

4. The vehicular antenna of claim 3, wherein the power supply part includes a second body having a diameter corresponding to a diameter of a cross-section of the spring part, a first insertion part formed at one surface of the second body to have a diameter smaller than the diameter of the second body, and a first probe formed at the other surface of the second body to receive a current.

5. The vehicular antenna of claim 3, wherein the transmission part includes a third body having a diameter corresponding to a diameter of a cross-section of the spring part, a second insertion part formed at one surface of the third body to have a diameter smaller than the diameter of the third body, and a second probe formed at the other surface of the third body to transmit a current to the metal part.

6. The vehicular antenna of claim 5, wherein the metal part is formed at the first body with a hole corresponding to the second probe.

7. The vehicular antenna of claim 1, wherein the third part is bent in a U shape or a V shape.

8. A vehicular antenna, comprising:

a first antenna disposed on a roof of a vehicle to receive a signal of a predetermined first band; and

a second antenna disposed on the roof of the vehicle to receive a signal of a predetermined second band at a shadow area of the first antenna;

wherein

the first antenna includes a spring part vertically disposed on the roof of the vehicle, a metal part vertically disposed at an upper surface of the spring part, a magnetic substance part formed at a bottom surface of the metal part, a power supply part disposed at a bottom surface of the spring part to supply a current, and a transmission part interposed between the spring part and the metal part to transmit a current, wherein the metal part includes;

a first part formed by being extended from a body;

a second part formed by being extended from the body to be spaced apart from the first part at a predetermined distance; and

a third part formed by being extended from the body to be interposed between the first part and the second part and to be bent at a predetermined angle with the first part and the second part.
