Abstract

A structure includes: a first conductor that extends in a second direction; a second conductor that faces the first conductor in a first direction and that extends along the second direction; a third conductor configured to capacitively connect the first conductor and the second conductor; a fourth conductor that is electrically connected to the first conductor and the second conductor, and that extends along a first plane; and a first resist layer that covers the fourth conductor. The fourth conductor includes a plurality of first areas exposed to outside via a plurality of through holes of the first resist layer. Each of the first conductor and the second conductor includes one or more second areas. The first resist layer extends on the first conductor and the second conductor to cover the fourth conductor, excluding the second areas. The first areas and the second areas are arranged along the first plane.

First claim

The invention claimed is:

1. A structure comprising:
a first conductor that extends in a second direction;
a second conductor that faces the first conductor in a first direction and that extends along the second direction;
a third conductor that is configured to capacitively connect the first conductor and the second conductor;
a fourth conductor that is electrically connected to the first conductor and the second conductor, and that extends along a first plane; and
a first resist layer that covers the fourth conductor, wherein
the fourth conductor includes a plurality of first areas exposed to outside via a plurality of through holes of the first resist layer,
each of the first conductor and the second conductor includes one or more second areas,
the first resist layer extends on the first conductor and the second conductor to cover the fourth conductor, excluding the second areas, and
the first areas and the second areas are arranged along the first plane.

2. The structure according to claim 1 , wherein
each of the first conductor and the second conductor includes a third area that is exposed to exterior space along the second direction, and
the third area is an area continuous from the second area.

3. The structure according to claim 1 , wherein
each of the first conductor and the second conductor include a plurality of the second areas, and
the plurality of second areas are arranged along a third direction in each of the first conductor and the second conductor.

4. The structure according to claim 1 , wherein
the third conductor includes a plurality of unit conductors, and
the unit conductors face each other along the first direction.

5. The structure according to claim 1 , further comprising a mounting board that has a plurality of second through holes formed therein and that faces the fourth conductor with a distance therebetween, wherein
the first areas and the mounting board are connected in such a way that the plurality of through holes do not overlap with any of the plurality of second through holes.

6. The structure according to claim 1 , wherein
the structure includes a feeding line that is connected to the third conductor, and
the feeding line is exposed from the first resist layer in an area surrounded by the first areas.

7. An antenna that is the structure according to claim 6 .

8. A wireless communication module comprising:
the antenna according to claim 7 ; and
an RF module that is electrically connected to the antenna.

9. A wireless communication device comprising:
the wireless communication module according to claim 8 ; and
a battery that is configured to supply electric power to the wireless communication module.
