Abstract

An antenna device having a shape of a polyhedron, includes a plurality of surface members that form surfaces of the polyhedron, and each of which having at least an antenna conductor, an insulating layer, and a shield layer are laminated from an upper layer side, and a frame body that has conductivity, fixes edge portions along sides of adjacent surface members inside the polyhedron, and has a joining member having an intersecting two-surface portion that conducts with the shield layer.

First claim

What is claimed is:

1. An antenna device having a shape of a polyhedron, comprising:
a plurality of surface members that form surfaces of the polyhedron, and each of which having at least an antenna conductor, an insulating layer, and a shield layer are laminated from an upper layer side; and
a frame body that has conductivity, fixes edge portions along sides of adjacent surface members inside the polyhedron, and has a joining member having an intersecting two-surface portion that conducts with the shield layer.

2. The antenna device according to claim 1 , wherein the joining member is an angle member having orthogonal two-surface portion and is made of steel or aluminum.

3. The antenna device according to claim 1 ,
wherein each of the plurality of surface members is formed in a quadrangle shape,
wherein a concave portion and a convex portion are formed in each side portion of the plurality of surface members in a direction along the each side portion with a step portion provided at a center of the each side portion as a boundary; and
wherein the polyhedron is a hexahedron in which the concave portions and the convex portions of adjacent surface members are fitted and assembled.

4. The antenna device according to claim 2 ,
wherein each of the plurality of surface members is formed in a quadrangle shape,
wherein a concave portion and a convex portion are formed in each side portion of the plurality of surface members in a direction along the each side portion with a step portion provided at a center of the each side portion as a boundary; and
wherein the polyhedron is a hexahedron in which the concave portions and the convex portions of adjacent surface members are fitted and assembled.
