Abstract

An antenna carrier (10) with an antenna (14) for electromagnetic radiation to be fastened to a wall (1) of a container composed of steel plate and having ventilation openings (5) which are covered on the exterior side of the container wall (1) by a cover (3) which protects against sprayed water, and which forms a cavity (6) in front of the ventilation openings (5), in which the cover (3) is composed of plastic, the antenna (14) projects through a ventilation opening (5) into the cavity (6) formed by the cover, the antenna carrier (10) is fastened on the interior side (9) of the container wall (1), and the antenna carrier (10) is the ground reference surface of the antenna (14) and is constructed as a magnetizable metal plate (11).

Claims

1. An antenna carrier with an antenna for electromagnetic radiation to be fastened to a wall of a container comprised of steel plate and having ventilation openings, wherein

the ventilation openings are covered on the exterior of the container wall by a cover comprised of synthetic resin material which protects against sprayed water and which forms a cavity in front of the ventilation openings;

the antenna projects through a ventilation opening into the cavity formed by the cover;

the antenna carrier is secured on the interior side of the container wall; and

the antenna carrier is the ground reference plane of the antenna and is constructed as a magnetizable metal plate.

2. An antenna carrier as claimed in claim 1, wherein the metal plate rests against the container wall in substantially planar contact with the wall.

3. An antenna carrier as claimed in claim 1, wherein the metal plate is provided with permanent magnetic surfaces for adhering the metal plate to the container wall.

4. An antenna carrier as claimed in claim 3, wherein the magnetic surfaces are constructed having opposite poles.

5. An antenna carrier as claimed in claim 3, wherein the metal plate is provided with a handle to facilitate detaching the magnetically adhered plate from the container wall.

6. An antenna carrier as claimed in claim 1, wherein the metal plate is provided with a removable spreading device, which is insertable into one of the ventilation openings.

7. An antenna carrier as claimed in claim 1, wherein the metal plate has a hole pattern matching the arrangement of the ventilation openings.

8. An antenna carrier as claimed in claim 7, wherein the antenna is inserted into one of the holes of the metal plate hole pattern.

9. An antenna carrier as claimed in claim 8, wherein at least the hole of the hole pattern in which the antenna is inserted is provided with a plastic border which engages in the matching ventilation opening.

10. An antenna carrier as claimed in claim 7, wherein a spreading device, which is insertable into a hole of the hole pattern and the matching ventilation opening, is provided for fastening the metal plate to the container wall.

11. An antenna carrier as claimed in claim 1, wherein the antenna comprises a flexible rod antenna.

12. An antenna carrier as claimed in claim 1, wherein the antenna comprises a flexible helical antenna.

13. An antenna carrier as claim in claim 12, wherein the antenna comprises a combination of helical and rod antennas designed for two different resonant frequencies.

14. An antenna carrier as claimed in claim 1, wherein the antenna is provided with an abrasion-resistant protective envelope.

15. An antenna carrier as claimed in claim 1, wherein multiple antennas, which are tuned to different frequencies, are fastened on separate metal plates.
