Abstract

A coupling structure for an antenna device including a housing, which retains an antenna element for transmitting or receiving a communication signal, and a wire harness, which extends out of the housing. The coupling structure includes a coupling member that couples the wire harness to a conductor when coupling the housing to a coupling location.

Claims

1. A coupling structure for an antenna device including a housing, which is couplable to a coupling location and retains an antenna element for transmitting or receiving a communication signal, and a wire harness, which extends out of the housing, the coupling structure comprising:

a coupling member that couples the wire harness to a conductor for coupling the housing to a coupling location.

2. The coupling structure according to claim 1, wherein the coupling member is arranged to couple the wire harness to the conductor at a position where the wire harness is extended from the housing to the coupling member over a length that is one fourth of a wavelength of the communication signal.

3. The coupling structure according to claim 1, wherein the coupling member is arranged to couple the wire harness in contact with the conductor.

4. The coupling structure according to claim 1, wherein the coupling member is arranged to couple the wire harness to the conductor over a length in a direction that the wire harness extends in which the length is greater than or equal to one eighth of a wavelength of the communication signal.

5. The coupling structure according to claim 4, wherein the coupling member has a length that is greater than or equal to one eighth of the wavelength in the direction that the wire harness extends.

6. The coupling structure according to claim 1, wherein the conductor is a metal pipe, and the coupling member is formed by a tube that fastens the wire harness to the metal pipe.

7. The coupling structure according to claim 1, wherein the conductor is a flat panel, and the coupling member is formed by a U-shaped member that fastens the wire harness to the flat panel.

8. The coupling structure according to claim 1, wherein the coupling location is the conductor and the coupling member is arranged to couple the wire harness to the coupling location.
