Definitions
- the invention relates to a vehicle antenna, which is preferably intended for mobile radio according to the preamble of claim 1.
- Such antennas as they are known as so-called disc antennas (see for example DE 44 43 596 A1) with radiators integrated in vehicle windows are known, have the disadvantage that they are arranged in an undesirable manner visibly around the vehicle are and require complex connection equipment.
- Vehicle antennas that are not visible are known, for example, from WO 99 21 247 A and DE 298 18 430 U.
- the first-mentioned publication describes antennas which are integrated in a non-conductive housing, for example a rear view mirror or a third brake light.
- the view cover is brought about by the non-transparent plastic housing.
- the antenna known from DE 298 18 430 U is for an arrangement below a body part, such as the trunk lid, provided.
- vehicle antennas that are not visible are also known from so-called bumper antennas.
- DE 41 16 232 A1 describes an antenna integrated in a non-conductive vehicle bumper, which is not visible as a result, but is at great risk in the event of a crash. This applies in particular to training with two probes connected to one another in the corner regions of the bumper by a line and possibly a line coupler, because the antenna is no longer functional even if the connecting line is interrupted.
- the required minimum distance of the spotlights from the metallic body serving as a reflector is increasingly rare in modern vehicles because the bumpers are no longer on display for design and safety reasons, but are arranged close to the body.
- the mutual distance is sometimes less than 20 mm, which results in a too strong capacitive coupling in the frequency ranges provided for mobile radio, which practically causes a short circuit of the antenna.
- a vehicle antenna known from DE 198 30 811 A1 such a small distance is also not possible because of the radar housing arranged on the inside of the bumper.
- the known bumper antennas are therefore severely limited in their area of application.
- an additional splash-proof opening is required to introduce the connecting line into the interior of the body, thereby increasing the manufacturing and assembly costs.
- the invention is therefore based on the object of a vehicle antenna at the outset to create the type mentioned in the simplest and cheapest possible way not visible, easy to connect, independent of the body material as well as their structure is not restricted by the part receiving them is not reduced the driver's field of vision and the vehicle interior and has a low risk of crash damage, in its effectiveness is independent of the distance of the spotlight from the body and none special body bushing required for a connecting cable.
- the characterizing features of claim 1 Because the antenna and the connecting line are not part of the attachment, the risk of damage, at least in the event of minor collisions, is significantly reduced in comparison to bumper antennas.
- the add-on part acts as a visual cover without additional effort, so that there is no obvious indication of the presence of a mobile radio device with the associated risk of theft. Above all, however, the separation of the antenna and the covering add-on part means that both can be optimally designed without compromise according to their desired electrical and mechanical function and do not result in any restrictions on usable space.
- the arrangement of the radiator in a body opening, in which the conductive body therefore does not serve as a reflector, also makes the antenna completely independent of the distance of the attachment from the radiator.
- the antenna is therefore also suitable for use in modern vehicles in which this distance is increasingly reduced.
- the support part can be designed without any effort so that any emitter structures can be attached to it.
- no additional and specially sealed body opening is required to pass the antenna connection cable; rather, cabling on the structural side is made possible in a cost-saving manner.
- the Counterweight can be connected to an additional reference potential such as For example, that of a metallic body can be dispensed with, thereby reducing the effort is further reduced in manufacture and assembly.
- the training does as a coordinated counterweight and the dimensioning of the invention Body opening a lock for jacket shafts on the feed line.
- a slot antenna according to claim 5 For installation sites with a low height, especially behind relatively narrow ones Crash protection strips, is an embodiment of the vehicle antenna according to the invention Suitable as a slot antenna according to claim 5, because the length of the body opening must be greater than ⁇ / 2, but its height (slot width) is small.
- An embodiment of the vehicle antenna according to claim 6 is particularly effective, regardless of whether it is designed as a monopole or as a slot antenna. Because the reflector only emits radiation to the outside, ie in the desired direction, and this with increased performance. The distance of the reflector from the spotlight can be exact have the optimal radio frequency value and is not, as with the bumper antenna, compromise deteriorating as the radiation properties shorten.
- the diagram is advantageous adaptable to the requirements of the individual case within certain limits.
- the directivity can be increased in certain angular ranges become.
- a dual-band antenna is created with minimal effort, which can be designed, for example, for the D and E network.
- These locking elements are simple and expediently constructed as LC elements (claim 11). However, they can also be designed as line resonant circuits.
- the board gives the radiator stability despite the thin conductor and is also much cheaper to attach than pure antenna wires.
- the LC blocking elements are simple and can be inserted into the conductor tracks in accordance with both the mechanical and the electrical requirements, advantageously in accordance with claim 13 in SMD technology.
- the dielectric of the circuit board also has an electrical shortening effect, so that the radiators and counterweights can be made smaller.
- the vehicle antenna according to claim 14 is therefore provided, the entire circuit board to be splash-proof coated with insulating material. It's special about that simple and practical to encapsulate or cast this component. At this Execution it is also possible to create practically any outer contour so that the component can be optimally adapted to the shape of the mounting surface.
- the potting compound also allows a defined component to be encased To give elasticity or to maintain its elasticity, especially then is advantageous if such components on strongly vibrating or vibrating Elements such as Vehicle parts are attached.
- thermoplastic hot-melt adhesive as a potting material according to claim 15 is particularly advantageous because, because of its short solidification time and the possibility of carrying out the injection molding process in the low-pressure range, it enables time-saving and inexpensive production.
- thermoplastic hot-melt adhesive due to the gluing by the hot-melt adhesive, an absolute tightness and at the same time a high strain relief of parts led out of the sheathing, such as cable sheaths, is achieved.
- the thermoplastic hot-melt adhesive forms a chemical bond with them, at least on the surface, which is absolutely leak-proof and ensures high strain relief.
- the circuit board is on an existing one for other purposes non-conductive support member attached (claim 16). This is not just one ensures stable arrangement, but this spotlight component at any time on the vehicle retrofitted. It can of course also be used as initial equipment on or in one Plastic carrier part can be integrated.
- a particularly suitable mounting location for the antenna according to the invention is provided in most cars for pressure equalization when the vehicle doors are quickly closed on both sides of the trunk, which are covered by plastic bumpers and are not easily visible behind them (claim 17).
- louvre-type ventilation flaps are usually fitted, which are provided with lugs that can be moved outwards, which open outwards under pressure from the vehicle interior and otherwise rest against the ventilation flaps to prevent the ingress of water.
- the monopoly and possibly the counterweights having components according to claim 18 to be attached to the ventilation flaps, whereby, of course, the mobility of the rags must not be hindered.
- a particularly simple and sufficiently stable attachment is listed in claim 19.
- the holding pins are inexpensive according to claims 20 and 21 made in one piece with the ventilation flaps, for example by injection molding.
- the the antenna part having the radiator is then only for mounting on the associated one To snap on the ventilation flap.
- the vehicle antenna consists of two separate radiator parts 1, each with one Grid-shaped reflector, not shown, arranged towards the vehicle interior.
- Each radiator part 1 consists of a monopole 2 and two adapted counterweights 3 connected to its base point A, which protrude in opposite directions orthogonally, and one LC blocking element 4 which is switched into the monopoly 2 and the counterweights 3.
- Monopoly 2 and counterweights 3 are arranged as printed conductor tracks on a one-sided laminated T-shaped printed circuit board 5, into which the LC blocking elements designed as SMD components are connected in series. The total length of the monopole 2 and the counterweights 3 is matched to the D-network frequency range.
- the LC blocking elements 4 are designed for the E-network frequency range and are arranged in such a way that their distance from the base point A of the monopole 2 corresponds approximately to 1 ⁇ 4 of the mean operating wavelength in this frequency range. This creates a broadband dual-band antenna that works in both the D and E network frequency ranges.
- Each radiator part 1 is on the outward-facing side in a plastic injection molding process manufactured ventilation flap 6 attached. This points to this one-piece retaining pin 7 with locking lugs 8 on the 1 holes when the radiator part is mounted 9 penetrate the circuit board 5 and reach behind it with a click.
- the fan flaps 6 each have a frame 10 and four sloping grille surfaces 11, each of which is attached to the frame 10 with the upper longitudinal edge this edge is assigned to movable tabs 12, of which only one in FIG. 2 is shown.
- the fan flaps 6 are in body openings on both sides of the trunk of the vehicle 13 14 attached by the side extensions of the rear bumper 15 are arranged concealed. If there is excess pressure inside the vehicle, for example when a vehicle door is closed quickly, it is closed Air escaping from the fan flaps to the outside is broken down.
- the Tabs 12 first pivoted outwards by the excess pressure; after pressure equalization they are then again close to the grid surfaces 11 and protect the Trunk so before splashing water.
- the two radiator parts 1 are (in the known from DE 41 16 232 A1 Way) interconnected via feed lines and a line coupler and via a connection cable to a transceiver for the mobile radio areas of the D and E network supplied.

Description
In der zuerst genannten Druckschrift sind Antennen beschrieben, die in einem nicht leitenden Gehäuse z.B. eines Rückspiegels oder einer dritten Bremsleuchte integriert sind. Die Sichtabdeckung wird dabei durch die nicht transparenten Kunststoffgehäuse bewirkt.
Außerdem steht der erforderliche Mindestabstand der Strahler von der als Reflektor dienenden metallischen Karosserie in modernen Fahrzeugen immer seltener zur Verfügung, weil die Stoßfänger aus Design- und Sicherheitsgründen nicht mehr ausgestellt, sondern dicht an der Karosserie angeordnet werden. Der gegenseitige Abstand ist dabei teilweise kleiner als 20 mm, wodurch sich in den für Mobilfunk vorgesehen Frequenzbereiche in eine zu starke kapazitive Kopplung ergibt, die praktisch einen Kurzschluss der Antenne bewirkt.
Bei einer aus der DE 198 30 811 A1 bekannten Fahrzeugantenne ist ein derartig geringer Abstand auch wegen des an der Innenseite des Stoßfängers angeordneten Radargehäuses nicht möglich.
Die bekannten Stoßfängerantennen sind damit in ihrem Anwendungsbereich stark eingeschränkt. Überdies wird zur Einführung der Anschlussleitung in das Innere der Karosserie in dieser eine zusätzliche spritzwasserdichte Öffnung benötigt und dadurch der Herstellungs- und Montageaufwand erhöht.
Vor allem aber ist durch die Trennung von Antenne und abdeckendem Anbauteil ohne Mehrkosten erreicht, dass beide ohne Kompromisse entsprechend ihrer gewünschten elektrischen und mechanischen Funktion optimal gestaltbar sind und keine Nutzraumbeschränkungen bewirken.
Außerdem ist das Trägerteil ohne Aufwand so zu gestalten, dass darauf beliebige Strahlerstrukturen angebracht werden können.
Nicht zuletzt ist bei der erfindungsgemäßen Anordnung der Fahrzeugantenne keine zusätzliche und speziell abzudichtende Karosserieöffnung zur Durchführung des Antennenanschlusskabels erforderlich, vielmehr ist in kostensparender Weise eine rohbauseitige Verkabelung ermöglicht.
Besonders vorteilhaft ist es, als Anbauteil ein bereits für andere Zwecke vorhandenes Element mitzubenutzen und damit zusätzliche Bauteile einzusparen. Die in den Ansprüchen 2 und 3 angeführten Alternativen weisen darüber hinaus den Vorteil auf, dass sich Stoßfänger wie auch Rammschutzleisten über größere Bereiche erstrecken, innerhalb derer die Karosserieöffnung angeordnet werden kann.
Diese Sperrglieder sind einfach und zweckmäßig als LC-Glieder aufgebaut (Anspruch 11). Sie können jedoch auch als Leitungsschwingkreise ausgebildet sein.
Überdies sind die LC-Sperrglieder einfach und sowohl den mechanischen als auch den elektrischen Anforderungen entsprechend in die Leiterbahnen einfügbar, in vorteilhafter Weise etwa gemäß Anspruch 13 in SMD-Technik.
Schließlich wirkt das Dielektrikum der Platine auch elektrisch verkürzend, so dass Strahler und Gegengewichte kleiner ausführbar sind.
Darüber hinaus ist aufgrund der Verklebung durch den Heißschmelzkleber eine absolute Dichtheit und zugleich eine hohe Zugentlastung von aus der Ummantelung herausgeführten Teilen wie beispielsweise Kabelmänteln erreicht. Der thermoplastische Heißschmelzkleber geht bei Kabelmänteln aus thermoplastischem Kunststoff, z.B. PVC oder PE, mit diesen zumindest an der Oberfläche eine chemische Verbindung ein, die absolut dicht ist und eine hohe Zugentlastung gewährleistet.
In diesen Karosserieöffnungen sind in der Regel jalousieartige Lüftungsklappen angebracht, die mit nach außen beweglichen Lappen versehen sind, welche sich auf Druck vom Fahrzeuginneren nach außen öffnen und ansonsten an den Lüftungsklappen anliegen, um das Eindringen von Wasser zu verhindern.

Monopol 2 und Gegengewichte 3 sind als gedruckte Leiterbahnen auf einer einseitig kaschierten T-förmigen Leiterplatine 5 angeordnet, in die die als SMD-Bauteile ausgebildeten LC-Sperrglieder in Reihe eingeschaltet sind.
Die Gesamtlänge des Monopols 2 und der Gegengewichte 3 ist jeweils auf den D-Netz-Frequenzbereich abgestimmt. Die LC-Sperrglieder 4 sind für den E-Netz-Frequenzbereich ausgelegt und so angeordnet, dass ihr Abstand vom Fußpunkt A des Monopols 2 etwa einem ¼ der mittleren Betriebswellenlänge in diesem Frequenzbereich entspricht. Damit ist eine breitbandige Dual-Band-Antenne realisiert, die sowohl im D- als auch im E-Netz-Frequenzbereich arbeitet.
