## Abstract

An array antenna device according to an embodiment of the present invention includes an array antenna, a core layer, and a first adhesive layer. The array antenna has a first surface on which one or more radiating elements are disposed. The core layer is disposed facing the first surface. The first adhesive layer is present between the array antenna and the core layer and bonds the array antenna and the core layer to each other. The first adhesive layer includes one or more first openings and one or more radiating elements are disposed inside the first opening.

## Claims

### Claim 1

An array antenna device comprising:
an array antenna that has a first surface on which one or more radiating elements are disposed;
a core layer that is disposed facing the first surface; and
a first adhesive layer that is present between the array antenna and the core layer and bonds the array antenna and the core layer to each other,
wherein the first adhesive layer includes one or more first openings, and
at least one of the radiating elements is disposed entirely inside any one of the first openings.

### Claim 2 (depends on 1)

The array antenna device according to claim 1, further comprising a skin layer that has a higher dielectric constant than the core layer and is disposed facing the surface of the core layer opposite to the first surface.

### Claim 3 (depends on 2)

The array antenna device according to claim 2, wherein the core layer is a resin foam or an insulating honeycomb structure.

### Claim 4 (depends on 2)

The array antenna device according to claim 2, further comprising a second adhesive layer bonding the skin layer and the core layer to each other.

### Claim 5 (depends on 4)

The array antenna device according to claim 4, wherein at least one of the first adhesive layer and the second adhesive layer is a sheet-shaped resin layer.

### Claim 6 (depends on 4)

The array antenna device according to claim 4, wherein
the second adhesive layer includes a third opening, and
one or more radiating elements are disposed in a portion in the array antenna which is directly below the third opening.

### Claim 7 (depends on 2)

The array antenna device according to claim 2, wherein
the core layer includes a second opening, and
one or more radiating elements are disposed in a portion in the array antenna which is directly below the second opening.

### Claim 8 (depends on 1)

The array antenna device according to claim 1, further comprising a reinforcement fixed to a second surface opposite to the first surface.

### Claim 9 (depends on 8)

The array antenna device according to claim 8, wherein the reinforcement is bonded to the second surface.

### Claim 10 (depends on 1)

The array antenna device according to claim 1, wherein the array antenna is formed on a dielectric substrate.

### Claim 11 (depends on 1)

The array antenna device according to claim 1, wherein the first adhesive layer penetrates into the core layer.

### Claim 12 (depends on 1)

The array antenna device according to claim 1, wherein the first adhesive layer has a protrusion into a surface of the core layer which is facing the first surface.

### Claim 13 (depends on 1)

The array antenna device according to claim 1, wherein the first adhesive layer is non-uniform.

### Claim 14 (depends on 1)

The array antenna device according to claim 1, wherein the one or more radiating elements and the first adhesive layer are not bonded to each other.
