Abstract

A vehicle antenna includes a coplanar wave guide including a planar dielectric body, a signal conductor arranged on the dielectric body, and a pair of ground conductors that hold both sides of the signal conductor via slots; a ground plane provided on an opposite side of the dielectric body from the signal conductor and the ground conductors; and an inverted-F antenna including a power feeding unit coupled to the signal conductor, a shorting unit coupled to one of the ground conductors, and a radiation unit coupled to an end portion of the power feeding unit and coupled to an end portion of the shorting unit, the radiation unit extending in a prescribed extension direction. The radiation unit is positioned on the ground plane side with respect to the dielectric body.

Claims (44)

1 . A vehicle antenna, comprising:

a coplanar wave guide including a planar dielectric body, a signal conductor arranged on the dielectric body, and a pair of ground conductors that hold both sides of the signal conductor via slots;

a ground plane provided on an opposite side of the dielectric body from the signal conductor and the ground conductors; and

an inverted-F antenna including a power feeding unit coupled to the signal conductor, a shorting unit coupled to one of the ground conductors, and a radiation unit coupled to an end portion of the power feeding unit and coupled to an end portion of the shorting unit, the radiation unit extending in a prescribed extension direction,

wherein the radiation unit is positioned on the ground plane side with respect to the dielectric body.

2 . The vehicle antenna according to claim 1 ,

wherein a length of the radiation unit in a direction that the radiation unit extends is less than or equal to a length of the ground plane in the direction that the radiation unit extends.

3 . The vehicle antenna according to claim 1 ,

wherein the radiation unit faces the ground plane.

4 . The vehicle antenna according to claim 2 ,

wherein the radiation unit faces the ground plane.

5 . The vehicle antenna according to claim 1 ,

wherein the radiation unit is inclined with respect to the ground plane.

6 . The vehicle antenna according to claim 2 ,

wherein the radiation unit is inclined with respect to the ground plane.

7 . The vehicle antenna according to claim 1 ,

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

8 . The vehicle antenna according to claim 2 ,

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

9 . The vehicle antenna according to claim 3 ,

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

10 . The vehicle antenna according to claim 4 ,

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

11 . The vehicle antenna according to claim 5

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

12 . The vehicle antenna according to claim 6 ,

wherein the power feeding unit and the shorting unit extend beyond the dielectric body.

13 . The vehicle antenna according to claim 1 ,
