Antenna assembly

1. A method for manufacturing an antenna assembly, the method comprising the step of assembling a first and a second assembly portion, the first assembly portion comprising:

a first elongated reflector body serving as a reflector for electromagnetic power radiated by the first antenna assembly portion,

a first set of antenna element receiving means located in a linear row along a first longitudinal direction of said reflector body, for respectively receiving an antenna element, and

side portions along the long sides of said reflector body,

wherein said second assembly portion comprises:

a second elongated reflector body serving as a reflector for electromagnetic power radiated by said second assembly portion, and

a second set of antenna element receiving means located in a linear row along a second longitudinal direction of said second reflector body for respectively receiving an antenna element, said second longitudinal direction being at least substantially parallel to said first longitudinal direction, and side portions along the long sides of said second reflector body,

the method comprising fastening said first and second assembly portions to each other along a respective adjacent side portion of said first and second assembly portions so as to form a dual array antenna assembly.

2. A method according to claim 1 , wherein the reflector bodies each have a substantially planar portion upon which the said antenna elements are arranged.

3. A method according to claim 1 , wherein the reflector bodies are comprised of a metal sheet, and wherein said side portions are produced by bending the metal sheet by one or more longitudinal bends into side portions of a desired shape.

4. A method according to claim 1 , wherein each of said assembly portions is arranged for receiving and/or transmitting signals in at least one frequency band, respectively, said two frequency bands being at least partially overlapping.

5. A method according to claim 1 , wherein an isolation layer is imposed between the said assembly parts side portions so as to ensure that the assembly parts are fastened to each other in a non-conducting manner.

6. A method according to claim 1 , wherein said antenna assembly portions are securely fastened to each other by means of mechanical fasteners.

7. A method according to claim 1 , wherein more than two assembly portions are being fastened to each other so as to form a multi-array antenna assembly.

8. A method according to claim 1 , further including the step of fitting antenna elements to said antenna element receiving means prior to or after fastening said first assembly portion to the said second assembly portion.

9. A method according to claim 1 , wherein each of said first and second reflector bodies further comprises at least one antenna aperture associated with each antenna element receiving means.

10. A method according to claim 1 , wherein said first reflector body and the second reflector body are substantially identical.

11. A method according to claim 1 , further comprising the step of enclosing the said antenna assembly portions by a common protective housing.

12. An antenna assembly that has been manufactured according to the method of claim 1 .

13. An antenna assembly, comprising:

a first assembly portion comprising:

a first elongated reflector body serving as a reflector for electromagnetic power radiated by the first antenna assembly portion,

a first set of antenna element receiving means located in a linear row along a first longitudinal direction of said reflector body, for respectively receiving an antenna element, and

side portions along the long sides of said reflector body;

a second assembly portion comprising:

a second elongated reflector body serving as a reflector for electromagnetic power radiated by said second assembly portion, and

a second set of antenna element receiving means located in a linear row along a second longitudinal direction of said second reflector body for respectively receiving an antenna element, said second longitudinal direction being at least substantially parallel to said first longitudinal direction, and side portions along the long sides of said second reflector body; and

means for fastening said first and second assembly portions to each other along a respective adjacent side portion of said first and second assembly portions so as to form a dual array antenna assembly.

14. An antenna assembly according to claim 13 , wherein said means for fastening comprises a mechanical fastener.

15. An antenna assembly as set out in claim 13 , further comprising an isolation layer configured between the side portions of said first and second assembly portions.
