- the vehicle-mounted antenna device of the present invention has a composite antenna element 10 incorporated in a spoiler 2 fixed to a vehicle 1, for example.
- the example incorporated in a rear spoiler was shown.
- the spoiler is a so-called aero part provided outside the vehicle body from the viewpoint of aerodynamics and design of the vehicle.
- the vehicle-mounted antenna device of the present invention is not limited to the one built in the spoiler.
- a resinous back door, a resin roof, or a resin can be used as long as it allows radio waves to pass through, that is, is not covered with metal or the like. It can be built in a hollow body such as a trunk.
- the composite antenna element 10 has an antenna length corresponding to the first frequency band, is bent to improve the antenna effective capacity so as to function also as a capacitive antenna corresponding to the second frequency band, and is arranged in a substantially planar shape. It is what is done.
- the first frequency band may be a frequency band such as a radio FM band, DAB (Digital Audio Broadcast), or UHF (Ultra-High Frequency).
- the antenna element only needs to have an antenna length of, for example, 1/4 of the target frequency according to these frequency bands.
- the second frequency band refers to, for example, a radio AM band.
- an antenna element bent to function as a capacitive antenna is used in order to correspond to the second frequency band. That is, the antenna length of the antenna element is made to correspond to the first frequency band, and the antenna effective capacity is improved by bending the antenna element into a substantially planar shape so that it becomes a capacitive antenna corresponding to the second frequency band.
- the bent shape may be, for example, one having at least one of a meander shape, a spiral shape, and a space filling curve shape.

- 2A is an example of a meander shape
- FIG. 2B is an example of a spiral shape
- FIG. 2C is an example of a space filling curve shape.
- the present invention is not limited to these illustrated examples, and any element shape may be used as long as the element is bent so as to be a capacitive antenna and the element length corresponds to a predetermined frequency band. good. Moreover, you may use combining these various shapes suitably.
- the composite antenna element 10 can be formed in various element shapes according to the internal space of the spoiler 2, for example. 2B, for example, as shown in FIG.
- the composite antenna element 10 is not limited to the one arranged on the substrate, and may be arranged on the film like a film antenna. Further, it may be directly mounted on the housing of the in-vehicle antenna device.
- the composite antenna element 10 is arranged so that the plane direction is substantially perpendicular to the metal body of the vehicle 1.
- substantially perpendicular does not need to be exactly perpendicular to the metal body, and is substantially perpendicular so that, for example, an angle may be given to some extent according to the internal space of the spoiler 2. Since the metal body of the vehicle 1 is conductive, there is a possibility that the metal body of the vehicle 1 is coupled to the composite antenna element 10. Therefore, in order to reduce the coupling amount, the metal body of the vehicle 1 is preferably in a substantially vertical positional relationship.
- the composite antenna element 10 may be arranged at an angle on the side perpendicular to the metal body as much as possible.
- the composite antenna element 10 is a hollow body.
- the vehicle traveling direction side is lowered as much as possible and the side opposite to the vehicle traveling direction is raised.
- the metal body may be arranged at an angle on the vertical direction side.
- the in-vehicle antenna device includes one in which the planar direction of the composite antenna element is not parallel to the metal body but is arranged at an angle on the vertical direction side. As a result, the amount of coupling with the metal body can be reduced.
- the composite antenna element 10 used in the vehicle-mounted antenna device of the present invention is, for example, inside the spoiler with respect to the vehicle traveling direction. Is arranged on either side of the offset.
- the composite antenna element 10 is grounded to the metal portion of the vehicle 1 in the vicinity of the offset arrangement position.
- the offset is arranged on the right side as viewed from the rear of the vehicle.
- the present invention is not limited to this, and may of course be arranged on the left side.
- the offset arrangement position of the composite antenna element 10 may be a position that does not interfere with the high-mount stop lamp 3 installed near the center of the spoiler. If the antenna element is arranged so as to overlap the high mount stop lamp 3, the S / N characteristic is deteriorated due to interference with the high mount stop lamp 3. Therefore, the composite antenna element 10 may be disposed near either the left or right end avoiding the high-mount stop lamp 3 installed near the center.
- FIG. 3A and 3B are diagrams for explaining the directivity of the vehicle-mounted antenna device of the present invention.
- FIG. 3A shows the directivity of the horizontal polarization in the FM band
- FIG. 3B shows the vertical of the FM band.
- Polarization directivity As a comparative example, the characteristic of the linear monopole antenna element of the prior art is represented by a dotted line, and the characteristic when arranged in the center is represented by an alternate long and short dash line. As shown in the figure, with respect to the horizontal polarization characteristics, it can be seen that a null is generated in the front-rear direction of the vehicle traveling direction in the case of a linear monopole antenna element or a central arrangement.
- the in-vehicle antenna device according to the present invention is offset, the radiation pattern is not equal to the left and right due to the metal body shape of the vehicle 1, so that it is not offset left and right, and there is no significant gain deterioration direction. As a result, it can be seen that the averaging gain is improved and the directivity deviation is reduced.
- the sub antenna 20 may be offset on the opposite side of the position where the composite antenna element 10 is offset.
- the sub-antenna 20 is, for example, an FM band sub-antenna, and it is also possible to configure diversity with a composite antenna element that is a main antenna.
- the sub antenna 20 may be disposed inside the spoiler on the side opposite to the offset arrangement position of the composite antenna element 10. Moreover, you may arrange
- the sub-antenna 20 is not limited to the FM band antenna but may be an antenna of another frequency band such as DAB or DTV, for example, and the arrangement position can be set to a position where mutual coupling does not occur. As a result, further compounding is possible.
- the linear monopole antenna element of the prior art there is a problem of mutual coupling with the sub-antenna because the element exists linearly in the entire spoiler. Since it can be arranged on the opposite side to the offset arrangement position, the influence of mutual coupling can be reduced.
- FIG. 4 is a schematic plan view for explaining an example in which the composite antenna element of the in-vehicle antenna device of the present invention is provided on a substrate.
- a composite antenna element 10 is provided on an antenna substrate 11.
