## Abstract

The radome (10) for vehicles comprises a substrate (18) formed of a radio transmissive resin, the substrate (18) having a proximal face and a distal face and a decoration layer (20) applied to the proximal face, the decoration layer (20) comprising a metalloid or a metalloid alloy deposited on the surface of the proximal face, a transparent frontal cover (22) overlying the decoration layer (20), and a light source (11) that illuminates the substrate (18), so that the light from the light source (11) crosses the transparent frontal cover (22). It permits to maintain its metallic aspect in any lighting condition, so that the decorative function is be improved by adding illumination in appropriate conditions while preserving the radar functionality.

## Claims

### Claim 1

A radome (10) for vehicles, comprising:
a substrate (18) formed of a radio transmissive and light diffusing resin, the substrate (18) having a proximal face and a distal face and a decoration layer (20) applied to the proximal face, the decoration layer (20) comprising a metalloid or a metalloid alloy deposited on the surface of the proximal face,
a transparent frontal cover (22) overlying the decoration layer (20),
characterized in that it also comprises a light source (11) that illuminates the substrate (18), so that the light from the light source (11) crosses the transparent frontal cover (22).

### Claim 2 (depends on 1)

A radome (10) for vehicles according to claim 1, wherein it also comprises a rear transparent cover (24), and the light source (11) is placed in said rear transparent cover (24).

### Claim 3 (depends on 1)

A radome (10) for vehicles according to claim 1, wherein the decoration layer (20) is translucent.

### Claim 4 (depends on 1)

A radome (10) for vehicles according to claim 1, wherein the decoration layer (20) is opaque and it is applied only to a portion of the proximal face of the substrate (18) leaving gaps for the passage of light from the light source (11).

### Claim 5 (depends on 2)

A radome (10) for vehicles according to claim 2, wherein the rear transparent cover (24) comprises an optical reflective coating (25) on its side opposite to the substrate (18), for reflecting the light from the light source (11).

### Claim 6 (depends on 1)

A radome (10) for vehicles according to claim 1, wherein the transparent frontal cover (22) comprises at least one pad (26) on one or more its portions on the side in contact with the substrate (18).

### Claim 7 (depends on 1)

A radome (10) for vehicles according to claim 1, wherein said metalloid or the metalloids of the alloy are selected from Germanium, Boron, Silicon, Arsenic, Antimony and/or Tellurium.

### Claim 8 (depends on 1)

Vehicle (14) including a radome (10) according to claim 1, including a front grill assembly (12), the radome (10) being positioned within the grill assembly (12), the vehicle (14) further including a radar antenna (16) positioned behind and in registration with the radome (10).
