Abstract

A structure includes: a base that includes a first surface and a second surface parallel to a first plane, a third surface and a fourth surface parallel to a second plane orthogonal to the first plane, and a fifth surface and a sixth surface parallel to a third plane orthogonal to the first plane and the second plane; a first conductor that expands along the third plane and that extends along a second direction; a second conductor that expands along the fourth plane and that extends along the second direction; a third conductor that expands along the first plane and that is configured to capacitively connect the first conductor and the second conductor; and a fourth conductor that is configured to be electrically connected to the first conductor and the second conductor. The first conductor, the second conductor, and the third conductor are at least partially exposed to exterior space.

First claim

a third conductor that expands along the first plane and that is configured to capacitively connect the first conductor and the second conductor; and
a fourth conductor that is configured to be electrically connected to the first conductor and the second conductor, wherein
the first conductor, the second conductor, and the third conductor are at least partially exposed to exterior space.

2. The structure according to claim 1 , wherein
in areas of the fifth surface and the sixth surface positioned between the first conductor and the second conductor in a first direction crossing the second direction, the third conductor is not exposed to the exterior space.

3. The structure according to claim 1 , wherein
the first conductor, the second conductor, and the third conductor are exposed to the exterior space at a first corner at which the first surface and the third surface intersect and at a second corner at which the first surface and the fourth surface intersect.

4. An antenna, comprising:
the structure according to claim 1 ; and
a feeding line that is connected to the third conductor.

5. A wireless communication module, comprising:
the antenna according to claim 4 ; and
