Definitions

• the invention relates to an antenna arrangement according to the preamble of claim 1.
• a generic antenna arrangement has become known, for example, from DE 201 11 229 U 1.
• an antenna arrangement for motor vehicles which has a chassis, above which a printed circuit board is arranged, specifically for receiving circuit components.
• One or more vertically projecting and at least partially flat antenna elements are provided vertically to the essentially horizontally oriented line board, namely for receiving different services or for the mobile radio range in different frequencies.
• a hood which can have a fin-like shape.
• Such antennas are usually attached to the motor vehicle body sheet, for example at the transition from the motor vehicle roof to the rear window.
• a multi-frequency antenna arrangement in particular for motor vehicles with a corresponding hood, has become known from EP 0 862 239 AI.
• the hood-shaped housing for example, two vertically aligned printed circuit boards which are laterally offset transversely to the vertical plane are provided for receiving the electronic components.
• a connection adapter is provided at the upper end of the housing, i.e. at the highest point of the hood in order to attach a whip-shaped antenna there.
• an antenna that can preferably be used for cars has also become known.
• This also has a hood-shaped housing, at the highest point of elevation of which a connection point for a whip-shaped antenna is provided.
• One or more vertically or horizontally oriented printed circuit board elements can be arranged within the antenna housing. In one embodiment, these are also arranged parallel to one another and transversely to the plane of the printed circuit board, next to one another, in an orientation transverse to the longitudinal axis of the vehicle. Likewise, however, they can also be arranged parallel to one another with a lateral offset, specifically in an alignment along the vehicle axis.
• antenna arrangements have also become known in which, based on a more or less horizontal chassis, the aforementioned printed circuit board with the electronic circuit components, filter assemblies, etc. is provided, and the antenna elements are in turn positioned perpendicular to it in the vertical direction.
• these can not only consist of metallically conductive self-supporting emitter devices, but also again, for example, of a conductor Circuit board element, ie generally made of a dielectric material, on which metallized surfaces are formed to form the radiators.
• radiator element is sufficient. If several services or one service are to be implemented several times, or if, for example, communication is to be made possible in different frequency bands in the mobile radio range, then a plurality of radiators or flat antenna elements which are offset from one another are naturally provided.
• one or more vertically aligned printed circuit boards are preferably used, which are preferably located next to one another in a common plane and are provided adjacent to the at least one antenna element.
• the use of a vertically aligned printed circuit board once again makes it possible to significantly simplify the overall structure of a corresponding antenna arrangement. It is surprising in this embodiment that the antenna diagram is not adversely affected in the manner to be expected by the vertically aligned printed circuit board attached to the side of the antenna element.
• the solution according to the invention is also distinguished, inter alia, by the fact that, in contrast to the prior art, the at least one antenna radiator arrangement is not provided above the printed circuit boards, but at the side next to this at least one printed circuit board. This avoids an unfavorable influence on the radiation characteristics. This is particularly surprising and not obvious, since such a broadband antenna for the mobile radio range is designed for wavelengths in the range of around 15 cm to 30 cm, and the size of the upright printed circuit board is therefore in the relevant range for these wavelengths ,
• a further antenna element is to be provided for a second frequency band for the mobile radio range or for the implementation of further services, this can also preferably be implemented as a flat antenna element in an area on the circuit board offset from the first antenna element.
• a further printed circuit board element can also be used, which lies in the same plane as the first printed circuit board element or, for example, with a parallel offset to the side in order to accommodate the at least one further antenna element here.
• the antenna elements and the possibly provided high-frequency circuit can thus preferably be accommodated on a single common printed circuit board arrangement.
• Figure 1 A schematic side view of an antenna arrangement with a side to it in a common plane in vertical cold-directional printed circuit board;
• Figure la an embodiment corresponding to figure
• Figure lb an embodiment modified again to Figure 1 and la, in which the antenna arrangement with a modified base is mounted on the upper edge of a rear window;
• Figure 2 is a schematic perspective representation of the embodiment of Figure
• FIG 3 shows a side view of a further modified exemplary embodiment of a printed circuit board with an antenna radiator located thereon.
• FIG. 1 shows a schematic side view, a motor vehicle body panel 1, for example at the rear roof end at the transition to a rear window 2 in a schematic side view.
• a base or base plate 7 is mounted from below with a vertically aligned printed circuit board 5 with surface sections 9 ′ which are electrically conductive thereon, whereby a radiator arrangement 9 is formed.
• the flat elements 9 ' are usually aligned in the longitudinal direction of the vehicle.
• the entire radiator arrangement 9 is usually attached to the symmetry line on the motor vehicle.
• the radiator arrangement 9 comprises a vertically extending first flat section 9 ', to which a whip-shaped, rearward-extending antenna section 9 "can then be connected.
• both antenna sections 9 'and 9" are electrically connected to one another via a combination consisting of inductance and capacitance 13.
• a printed circuit board 15 is provided on the first vertically extending planar radiator section 9 'in the same vertical plane, on which the possibly provided high-frequency circuit of the antenna arrangement is accommodated. In other words, all necessary electrical components and assemblies, filter modules, etc. are seated on this printed circuit board section 15.
• connection cables can then be inserted into the interior of the motor vehicle via an opening 16 provided in the base plate or the base plate 7. This is not shown in the second embodiment.
• FIG. sher perspective representation shown again, the three spatial coordinates X, Y and Z are shown to clarify the perspective.
• the entire arrangement is provided on a common printed circuit board 15.
• this common circuit board 15 leading in the direction of the motor vehicle that is to say in the exemplary embodiment shown in the drawing on the leading side 17 on the left, the planar radiator element 9 with the two planar radiator sections 9 ′, 9 ′′ and the combination consisting of inductance and capacitance 13 is provided, for example by a corresponding metallization formed on the printed circuit board 15.
• Rectangularly delimited space 15 is then again accommodated with the high-frequency circuit that may be provided with the corresponding components and components.
• a second radiator arrangement 29, for example on the common, vertically oriented printed circuit board 15 in the trailing region 18 of the printed circuit board 15, is e.g. provided in the form of a metallized surface.
• the possibly provided high-frequency circuit for the two radiator arrangements 9, 29 in the printed circuit board section 15 ' is accommodated on the common printed circuit board 15 between the two radiator arrangements 9, 29.
• the radiator arrangements 9 and 29 of FIG the printed circuit board 15 may be formed separately. But also in this exemplary embodiment, the printed circuit board 15 would preferably come to lie directly to the side between the two radiator arrangements 9, 29 in the vertical orientation.
• the entire arrangement is held mechanically by the base or the so-called base plate 7.
• certain sections of the printed circuit board 15 can also be omitted or broken out if, for example, an antenna element is to be accommodated there which, in deviation from the exemplary embodiment shown, is not oriented vertically, for example in the case of a GPS antenna.
• FIG. 1 a a further FIG. 1 a is shown, the main difference in FIG. 1 a compared to FIG. 1 being that the exemplary embodiment according to FIG. 1 a is a roof installation.
• the base or base plate 7 is mounted from above on the body panel 1, usually on the body roof, so that the base or base plate 7 covers the opening 3.
• the antenna arrangement can also be mounted on a window, preferably on a rear window of a motor vehicle, preferably at the upper edge in the vicinity of the transition to the body roof.
• a corresponding protection not shown is attached hood that covers and protects the entire antenna arrangement shown.
