Abstract

A composite antenna device comprising a plurality of antennas, the plurality of antennas having at least one particular antenna which differs in antenna characteristics, and at least either the particular antenna or at least one other antenna being of subassembly configuration.

Claims

1. A composite antenna device comprising a plurality of antennas, the plurality of antennas having at least one particular antenna which differs in antenna characteristics, and at least either the particular antenna or at least one other antenna being of subassembly configuration.

2. The composite antenna device as claimed in claim 1, wherein the at least one particular antenna comprises one antenna, and the at least one particular antenna is of the subassembly configuration.

3. The composite antenna device as claimed in claim 1, wherein the at least one particular antenna comprises one antenna, the at least one other antenna comprises a plurality of antennas, and the at least one particular antenna and the at least one other antenna are of separate subassembly configurations.

4. The composite antenna device as claimed in claim 1, wherein the at least one particular antenna differs in directivity from the at least one other antenna.

5. The composite antenna device as claimed in claim 1, wherein the at least one particular antenna is a vehicle composite antenna which differs from the at least one other antenna in that the at least one particular antenna is possibly not mounted depending on grade of a vehicle or user selection.

7. The composite antenna device as claimed in claim 1, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

8. The composite antenna device as claimed in claim 2, wherein the at least one particular antenna differs in directivity from the at least one other antenna.

9. The composite antenna device as claimed in claim 3, wherein the at least one particular antenna differs in directivity from the at least one other antenna.

10. The composite antenna device as claimed in claim 2, wherein the at least one particular antenna is a vehicle composite antenna which differs from the at least one other antenna in that the at least one particular antenna is possibly not mounted depending on grade of a vehicle or user selection.

11. The composite antenna device as claimed in claim 3, wherein the at least one particular antenna is a vehicle composite antenna which differs from the at least one other antenna in that the at least one particular antenna is possibly not mounted depending on grade of a vehicle or user selection.

12. The composite antenna device as claimed in claim 1, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

13. The composite antenna device as claimed in claim 3, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

14. The composite antenna device as claimed in claim 4, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

15. The composite antenna device as claimed in claim 5, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

17. The composite antenna device as claimed in claim 8, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

18. The composite antenna device as claimed in claim 9, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

19. The composite antenna device as claimed in claim 10, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

20. The composite antenna device as claimed in claim 11, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.

6. A vehicle composite antenna device comprising a GPS antenna, a VICS antenna and an ETC antenna, the ETC antenna being of subassembly configuration which is separated from a circuit board on which the GPS antenna and the VICS antenna are mounted on.

16. The composite antenna device as claimed in claim 6, wherein the antenna of subassembly configuration is housed in a radome different from a radome of other antennas.
