Abstract

A roof antenna attached to a vehicle includes an adhesive applied to a designated thickness, an upper case formed in a streamlined dome shape having an opened lower surface, and a lower case combined with the upper case, the lower case shielding the opened lower surface of the upper case and provided with an antenna module mounted on an upper surface of the lower case, wherein the lower case is combined with a roof of the vehicle, one surface of a pad formed of the adhesive is applied to a lower surface of the lower case, and another surface of the pad formed of the adhesive is attached to the roof.

Claims

1. A roof antenna attached to a vehicle, comprising:

an adhesive applied to a designated thickness;

an upper case formed in a streamlined dome shape having an opened lower surface; and

a lower case combined with the upper case, the lower case shielding the opened lower surface of the upper case and provided with an antenna module mounted on an upper surface of the lower case,

wherein the lower case is combined with a roof of the vehicle, one surface of a pad formed of the adhesive is applied to a lower surface of the lower case, and another surface of the pad formed of the adhesive is attached to the roof.

2. The roof antenna according to claim 1, wherein at least one diaphragm is formed on the lower surface of the lower case so as to prevent moisture or foreign substances from being introduced into the roof antenna.

3. The roof antenna according to claim 1, wherein at least one diaphragm is formed on the upper surface of the lower case and the antenna module is disposed between the at least one diaphragm, so as to prevent moisture or foreign substances from being introduced into the roof antenna.

4. The roof antenna according to claim 1, wherein at least one fastening part is formed on the lower case, and the lower case is attached to the roof through the at least one fastening part.

5. The roof antenna according to claim 1, wherein the pad formed of the adhesive is a double-sided adhesive pad and a protective tag to maintain adhesiveness of the adhesive is provided at both the one surface and the other surface of the double-sided adhesive pad.

6. The roof antenna according to claim 5, wherein the tag includes a portion protruding to the outside of the lower case.

15. The roof antenna according to claim 1, wherein the adhesive includes butyl.

7. A watertight structure of a roof antenna attached to a vehicle, comprising:

an upper case provided with at least one diaphragm formed thereon and having an opened lower surface;

a lower case combined with the upper case and provided with a groove formed at a part of the lower case connected to the at least one diaphragm;

a base disposed on the upper surface of the lower case and located under an antenna circuit board;

an elastic body combined with the base and including an inclined plane so as to form the groove; and

an adhesive applied to a designated portion of the at least one diaphragm in the groove and applied to a designated portion of the inclined plane of the elastic body.

8. The watertight structure according to claim 7, wherein an introduction of moisture and foreign substances into the roof antenna is prevented.

9. The watertight structure according to claim 7, wherein the base is formed of zinc or aluminum.

10. The watertight structure according to claim 7, wherein the base and the elastic body are formed through insert injection molding.

16. The watertight structure according to claim 7, wherein the groove is formed in a closed curve shape.

11. A watertight structure of a roof antenna attached to a vehicle, comprising:

an adhesive;

an upper case provided with at least one diaphragm formed thereon and having an opened lower surface;

a lower case combined with the upper case;

a base disposed on the upper surface of the lower case and located under an antenna circuit board; and

an elastic body combined with the base,

wherein a groove is formed on the base, the at least one diaphragm is disposed in the groove, and the adhesive is applied to a designated portion of the at least one diaphragm.

12. The watertight structure according to claim 11, wherein an introduction of moisture and foreign substances into the roof antenna is prevented.

13. The watertight structure according to claim 11, wherein the base is formed of zinc or aluminum.

14. The watertight structure according to claim 11, wherein the base and the elastic body are formed through insert injection molding.

17. The watertight structure according to claim 11, wherein the groove is formed in a closed curve shape.
