Abstract

To reduce a dielectric loss while determining a direction of an antenna formed on a flexible board.

An antenna device includes: a flexible board including an antenna and a signal line coupled to the antenna, the antenna and the signal line being formed on a front surface side of the flexible board; and a support that puts the flexible board in a predetermined shape, the support having a shape that does not cover at least a part of a second region of a back surface of the flexible board, the second region corresponding to a first region in which the antenna and the signal line are formed.

Claims

1. An antenna device comprising:

a flexible board including an antenna and a signal line coupled to the antenna, the antenna and the signal line being formed on a front surface side of the flexible board; and

a support that puts the flexible board in a predetermined shape,

the support having a shape that does not cover at least a part of a second region of a back surface of the flexible board, the second region corresponding to a first region in which the antenna and the signal line are formed.

2. The antenna device according to claim 1, wherein

the support has a shape that does not entirely cover the second region.

3. The antenna device according to claim 1, wherein

the support has a dielectric constant lower than a dielectric constant of the flexible board.

4. The antenna device according to claim 1, wherein

the support is bent such that the antenna can radiate a radio wave in a predetermined direction when the antenna device has been mounted.

5. The antenna device according to claim 1, wherein

the support is formed of a flexible material.

6. The antenna device according to claim 1, further comprising

a heat-dissipating member interposed between the flexible board and the support.
