Abstract

An antenna device includes a case, a first antenna and a second antenna in the case, the second antenna including a capacitance loading element. The capacitance loading element includes an inclined portion which extends from a front-upper side toward a rear-lower side at a front side of the capacitance loading element. The first antenna is provided in a front side with respect to the inclined portion.

Claims (51)

1. An antenna device comprising:

a first antenna and a second antenna, wherein

the second antenna includes a capacitance loading element,

the capacitance loading element includes an upper edge portion, a lower edge portion, and an inclined portion which extends from an upper side of a front end portion toward a rear-lower side at a front side of the capacitance loading element,

the inclined portion is disposed between the upper edge portion and the lower edge portion, and

the first antenna is provided in a front side with respect to the inclined portion.

2. The antenna device according to claim 1 , wherein the lower edge portion extends toward a rear side from a lower end of the inclined portion.

3. The antenna device according to claim 1 , wherein

the first antenna is provided in a lower side with respect to the capacitance loading element.

4. The antenna device according to claim 1 , wherein the capacitance loading element includes a right plate-like portion and a left plate-like portion that are separate portions.

5. The antenna device according to claim 1 , further comprising:

a base, wherein

the first antenna is provided on the base, and

the capacitance loading element is disposed above the base.

6. The antenna device according to claim 1 , wherein

the first antenna is an antenna configured to receive a satellite signal.

7. The antenna device according to claim 1 , wherein

the first antenna is a planer antenna.

8. The antenna device according to claim 1 , wherein

the second antenna is an AM/FM antenna.

9. The antenna device according to claim 1 , wherein

the capacitance loading element has a meandering portion.

10. The antenna device according to claim 1 , wherein

the front side of the capacitance loading element includes a turning around part turning around in a direction different from a front-rear direction and a top-bottom direction of the antenna device, and,

the turning around part extends parallel to the inclined portion.

11. An antenna device comprising:

a first antenna and a second antenna; and

a capacitance loading element,

the capacitance loading element includes an upper edge portion, a lower edge portion, and an inclined portion which extends from an upper side of a front end portion toward a rear-lower side at a front side of the capacitance loading element,

the inclined portion is disposed between the upper edge portion and the lower edge portion, and

the first antenna is provided in a front side with respect to the inclined portion.

12. The antenna device according to claim 11 , wherein the lower edge portion extends toward a rear side from a lower end of the inclined portion.

13. The antenna device according to claim 11 , wherein

the first antenna is provided in a lower side with respect to the capacitance loading element.

14. The antenna device according to claim 11 , wherein

the first antenna is a GNSS antenna.

15. The antenna device according to claim 11 , wherein the capacitance loading element includes a right plate-like portion and a left plate-like portion that are separate portions.

16. The antenna device according to claim 11 , wherein

the first antenna is provided in a lower side with respect to the second antenna.

17. The antenna device according to claim 11 , wherein

the first antenna is provided in a front side with respect to the second antenna.

18. The antenna device according to claim 11 , wherein

the second antenna is between the first antenna and the capacitance loading element in a front-rear direction.

19. The antenna device according to claim 11 , wherein

the second antenna is provided in a front side with respect to the inclined portion.

20. An antenna device comprising:

a first antenna and a second antenna, wherein

the second antenna includes a capacitance loading element, and

the capacitance loading element includes an upper edge portion, a lower edge portion, and an inclined portion which is inclined from an upper side of a front end portion toward a rear-lower side when viewed from a direction perpendicular to both of an arrangement direction of the first antenna and the second antenna and an upper-lower direction at a front side of the capacitance loading element, and

the inclined portion is disposed between the upper edge portion and the lower edge portion.

21. The antenna device according to claim 20 , wherein the lower edge portion extends toward a rear side from a lower end of the inclined portion.
