Abstract

A radar antenna is provided. The radar antenna includes an antenna body, a housing housing a plurality of components for controlling the antenna body, and a ventilation path formed in a predetermined ventilating direction and penetrating the housing. One or more of the plurality of components are disposed inside the housing to be separated from the rest of the components with respect to the ventilation path therebetween.

First claim

The invention claimed is:

1. A radar antenna configured for use on a ship, comprising:
an antenna body;
a housing accommodating a plurality of components for controlling the antenna body; and
a ventilation path formed in a predetermined ventilating direction and penetrating the housing, the ventilation path being arranged so that the ventilating direction is substantially horizontal and parallel to front-and-rear directions of the ship,
wherein one or more of the plurality of components are disposed inside the housing to be separated from the rest of the components with respect to the ventilation path therebetween, such that one or more of the plurality of components are disposed above the ventilation path and one or more of the plurality of components are disposed below the ventilation path,
wherein a floor face of the ventilation path inclines to be lower on one end side thereof.

2. The radar antenna of claim 1 , wherein the plurality of components include a heat generating body and one or more non-heat generating bodies, and
wherein the heat generating body is disposed separately from at least one of the one or more non-heat generating bodies with respect to the ventilation path therebetween.

3. The radar antenna of claim 1 , wherein the plurality of components at least include a first heat generating body and a second heat generating body, and
wherein the first heat generating body is disposed separately from the second heat generating body with respect to the ventilation path therebetween.

4. The radar antenna of claim 3 , wherein the first heat generating body is an oscillation element, and the second heat generating body is a heating element disposed on a circuit board for signal processing.

5. The radar antenna of claim 4 , wherein the ventilation path is formed into a rectangular duct-like shape, and
wherein the circuit board is disposed parallel to an outer circumferential surface of the rectangular duct-like ventilation path.

6. The radar antenna of claim 1 , further comprising a frame to which the plurality of components are attached,
wherein the ventilation path includes:
a ventilation section formed by the frame; and
a ventilation hole formed in the housing and communicating with the ventilation section.

7. The radar antenna of claim 1 , wherein the ventilation path is disposed below an oscillation element, a waveguide, and a rotary drive source of the antenna body.

8. The radar antenna of claim 1 , further comprising a display unit for displaying a radar image based on signals received by the radar antenna.

9. The radar antenna of claim 8 , wherein the plurality of components include a heat generating body and one or more non-heat generating bodies, and
wherein the heat generating body is disposed separately from at least one of the one or more non-heat generating bodies with respect to the ventilation path therebetween.

10. The radar antenna of claim 8 , wherein the plurality of components at least include a first heat generating body and a second heat generating body, and
wherein the first heat generating body is disposed separately from the second heat generating body with respect to the ventilation path therebetween.

11. A radar antenna configured for use on a ship, comprising:
an antenna body;
a housing accommodating a plurality of components for controlling the antenna body; and
a ventilation path formed in a predetermined ventilating direction and penetrating the housing, the ventilation path being arranged so that the ventilating direction is substantially horizontal and parallel to front-and-rear directions of the ship,
wherein one or more of the plurality of components are disposed inside the housing to be separated from the rest of the components with respect to the ventilation path therebetween, such that one or more of the plurality of components are disposed above the ventilation path and one or more of the plurality of components are disposed below the ventilation path,
wherein the housing has an overhanging portion protruding outward in the ventilating direction, near an upper area of an inlet of the ventilation path.

12. The radar antenna of claim 11 , wherein the plurality of components include a heat generating body and one or more non-heat generating bodies, and
wherein the heat generating body is disposed separately from at least one of the one or more non-heat generating bodies with respect to the ventilation path therebetween.

13. The radar antenna of claim 11 , wherein the plurality of components at least include a first heat generating body and a second heat generating body, and
wherein the first heat generating body is disposed separately from the second heat generating body with respect to the ventilation path therebetween.

14. The radar antenna of claim 13 , wherein the first heat generating body is an oscillation element, and the second heat generating body is a heating element disposed on a circuit board for signal processing.

15. The radar antenna of claim 14 , wherein the ventilation path is formed into a rectangular duct-like shape, and
wherein the circuit board is disposed parallel to an outer circumferential surface of the rectangular duct-like ventilation path.

16. The radar antenna of claim 11 , further comprising a frame to which the plurality of components are attached,
wherein the ventilation path includes:
a ventilation section formed by the frame; and
a ventilation hole formed in the housing and communicating with the ventilation section.

17. The radar antenna of claim 11 , wherein the ventilation path is disposed below an oscillation element, a waveguide, and a rotary drive source of the antenna body.

18. The radar antenna of claim 11 , further comprising a display unit for displaying a radar image based on signals received by the radar antenna.

19. The radar antenna of claim 18 , wherein the plurality of components include a heat generating body and one or more non-heat generating bodies, and
wherein the heat generating body is disposed separately from at least one of the one or more non-heat generating bodies with respect to the ventilation path therebetween.

20. The radar antenna of claim 18 , wherein the plurality of components at least include a first heat generating body and a second heat generating body, and
wherein the first heat generating body is disposed separately from the second heat generating body with respect to the ventilation path therebetween.
