Definitions

  • the invention relates to a motor vehicle multifunction antenna according to the preamble of claim 1.
  • a satellite-based radio system is in use, which works only with little distributed satellites in orbit.
  • antennas are to be offered, which must meet even at low elevation angles of 20 ° and more, in particular from 25 ° to 90 ° -Elevation the same minimum profit.
  • the corresponding systems are also known in the art as SDARS services, which transmit in the 2.3 GHz range.
  • the satellite signals are transmitted circularly polarized.
  • WO 01/80366 A1 a special antenna system has become known, which contains a cross-dipole, which is formed from a sheet material and thereby forms four quadrants which are separated from each other by the dipole walls. In each quadrant, a separate, vertically extending monopole is then placed over which the terrestrially transmitted, vertically polarized signals can be received.
  • a program reception should always be possible if the programs broadcast in parallel on satellite can no longer be received because, for example, the satellite, which is sometimes positioned very low on the horizon, is shielded by mountains, structures, tunnels, etc.
  • a corresponding receiving device for land vehicles for digital radio-frequency signals which are made available in a predetermined frequency band on the one hand by a satellite with a lower intensity and on the other hand in shading areas of a terrestrial transmitter with a much greater intensity, is also known for example from DE 202 07 401 U 1 became known. Since the terrestrial signals are received with much greater intensity, this prior publication proposes a Wilkinson divider, also referred to as a 3dB divider. In the one subsequent branch for this purpose, a further, ie a second amplifier, is provided, which amplifies the satellite signals with low intensity again by a further stage, in order to have approximately equal reception signals at the output of the overall circuit.
  • this prior publication does not include either a cellular antenna or, for example, a GPS receiver antenna for geo-positioning the land vehicle.
  • this antenna also comprises a rod-shaped mobile radio antenna as the second antenna device.
  • no location system is provided comparable to the GPS system for determining the respective position of the land vehicle.
  • a generic antenna arrangement for vehicles for receiving a plurality of different frequency bands separated by gaps has also become known from DE 101 33 295 A1. It is an antenna arrangement with four antennas, namely two broadband antennas for different mobile radio frequencies, a satellite-based car navigation antenna according to the GPS system and an antenna for Satellite Digital Audio Reception System SDARS. It should also be understood from the pre-publication that the SDARS antenna should have a configuration for both satellite-based and terrestrial operation with a vertical polarization.
  • US Pat. No. 6,441,792 B1 proposes a planar arrangement of antennas comprising a multiplicity of individual antenna elements which are located in a plane and are offset on a planar element in the longitudinal and / or transverse direction.
  • a roof module for a vehicle with at least one antenna is shown, wherein the structure may be such that, according to one embodiment, two antennas are provided, for example, radio (AM / FM) -, TV, GPS , GSM, DAB or SDARS antennas.
  • radio AM / FM
  • the car antenna is also at least an antenna for a mobile phone and a receiving antenna for Coordinate and thus to determine the position of a vehicle.
  • the antenna should have the smallest possible space, and this with very good reception qualities.
  • the surprising result is that due to the different order and arrangement of the individual antennas for the different services, it has become possible to construct an antenna arrangement for the various services, despite the overall highly compact arrangement with high integration density, which is nevertheless surprisingly good Has reception qualities.
  • a terrestrial receiving antenna for receiving terrestrial radiated radio programs and / or terrestrial radiated SDARS services for example, a GPS antenna
  • a satellite antenna for the reception of satellite-broadcast SDARS services and finally a mobile radio antenna are arranged.
  • the antenna i. the chassis has a longitudinal dimension, which can be under 18 cm, also easily under 17 cm. It has even been shown that the total length of the antenna receiving chassis can be easily reduced below 150 mm.
  • the accommodated in the leading portion of the fin-like housing cover antenna for receiving terrestrial radiated radio programs or SDARS services consists of a monopole, the subsequently arranged GPS antenna from a Patchstrahler and the GPS antenna downstream third antenna for receiving satellite-broadcast SDARS services also consists of a patch radiator.
  • the center distance between the two leading first antennas is smaller than the center distance between the second and third antenna and also smaller than the center distance between the third and fourth antenna.
  • FIG. 1 shows a schematic side view and in FIG. 2 a schematic plan view of an exemplary embodiment of an antenna arrangement according to the invention.
  • the antenna arrangement comprises a chassis 1, which is designed in a plan view a hull, surfboard, etc. comparable, namely with a comparatively narrow leading portion 3, and a wider contrast middle portion 5 and rear portion 7.
  • the chassis is usually made of a metallic Basic body, for example made of cast metal.
  • Such a chassis is usually mounted on a motor vehicle roof, for example at the rear end of the transition to the rear window, at this point in the motor vehicle either a recess or depression is provided in the body panel to the thus formed chassis 1 at a suitable altitude relative to the body panel position.
  • a recess or depression is provided in the body panel to the thus formed chassis 1 at a suitable altitude relative to the body panel position.
  • the leading narrower region 3 in the motor vehicle in the direction of travel forward, so that the rear portion 7 comes to rest at the rear.
  • the corresponding antenna is usually mounted centrally on the vehicle and is protected by a housing cover 9 which preferably has a fin body shape, as can be seen in the schematic rear view according to FIG.
  • the antenna C can be designed for the reception of digital high-frequency signals, according to the SDARS services in North America. In this way, these signals are broadcast in a frequency range of about 2.3 GHz.
  • terrestrial radiated radio programs can be received.
  • such antennas are required for receiving the SDARS services, especially since the SDARS services emitting satellites are sometimes not positioned in their optimal position as vertically as possible above the receiving vehicle, but sometimes very low on the horizon, up to an elevation angle of about 20 ° or for example about 25 °. This has the consequence that these signals emitted by satellites are frequently shielded, for example in canyons, tunnels, under bridges, etc.
  • partly terrestrially positioned transmission positions are provided, so that parallel to these Situations the radio programs can be received via the terrestrial antenna A.
  • the location system is preferably the GPS positioning system in use worldwide. However, other positioning systems, such as the currently planned in Europe Galileo are suitable to be received with such a receiving antenna.
  • a mobile radio antenna D is preferably proposed.
  • This mobile radio antenna may be suitable for communication in different mobile radio ranges, for example for reception in the 900 MHz range, in the 1.8 GHz range or, for example, in the 1700 to 2170 MHz range, of the type of design, size etc. Therefore, the mobile radio antenna may be suitable not only for receiving one of these frequency bands, but also for receiving two or three or more generally more of the said or other frequency bands.
  • the mobile radio antenna may for this purpose consist of a vertically rising relative to the chassis 1 substrate, for example, a printed circuit board, on which correspondingly conductive surfaces are formed as antenna elements.
  • the overall length of the chassis may be less than 170 mm, for example less than 160 mm or even 150 mm.
