Definitions

  • the invention relates to a flat-construction mobile radio antenna according to the features of the preamble of patent claim 1.
  • a roof antenna manufactured by the applicant has a base plate which is produced by casting. This base plate receives one or more radiators for transmitting and / or receiving high-frequency signals and is inserted via a downwardly directed threaded pin in an opening of the vehicle roof and screwed there.
  • a protective cover made of plastic is provided which extends over the radiator. It is for optical and aerodynamic reasons of disadvantage that this plastic hood is directed several centimeters in height. This is partly also necessary so that the radiators, which must have a certain spatial extent for transmitting and / or receiving the high-frequency signals, even fit under the cover.
  • the invention is therefore based on the object to provide a mobile radio antenna for a vehicle for receiving and / or transmitting high-frequency signals, which at least retains the previously achieved transmission and / or reception properties or is improved to that effect, at the same time particularly flat design, especially at a height of ⁇ 20 mm.
  • the at least one antenna element for receiving and / or transmitting high-frequency signals is oval or semi-oval-shaped.
  • the oval antenna element preferably extends over almost the entire base area of the mobile radio antenna, while the semi-oval-shaped antenna element extends approximately over one half of the base area of the mobile radio antenna.
  • This form has, as has surprisingly been found, the advantage that signals of a few hundred megahertz or a few gigahertz can be easily sent and / or received, while the plane-parallel to a base of the mobile antenna arranged oval or semi-oval shaped antenna element a particularly flat-built mobile radio antenna results.
  • the at least one antenna element is arranged at a certain distance plane-parallel to the mass element of the mobile radio antenna.
  • another, likewise oval or semi-oval-shaped antenna element is arranged in the same plane in the first antenna element, wherein a slot is present between the two antenna elements. Due to the different planar extent and shape of the two antenna elements, it is possible to transmit and / or receive high-frequency signals in different frequency ranges while maintaining the flat design of the mobile radio antenna.
  • the first antenna element which is arranged around the further antenna element for example, for the reception of high-frequency signals in the range of 900 megahertz is formed.
  • mobile services such as AMPS or GSM 900 can be received.
  • the further antenna element arranged within the first antenna element is designed such that it is suitable, for example, for high-frequency signals in the frequency range around 1800 to 2200 megahertz. This can be used to receive mobile services, such as GSM 1800, PCS 1900 and UMTS.
  • mobile services such as GSM 1800, PCS 1900 and UMTS.
  • GSM 1800, PCS 1900 and UMTS mobile services
  • the two oval or semi-oval antenna elements which are nested and arranged in the same plane planparallel (coplanar) to the ground plane (mass element) of the mobile antenna, the advantage that the high-frequency signals of different services can be sent and / or received at the same time flat construction (preferably a height ⁇ 20 mm) is given.
  • the figure shows as part of a mobile radio antenna according to the invention for use in or on vehicles a mass element 1, which forms a base plate.
  • the mass element 1 is formed as a printed circuit board with arranged thereon electrically conductive regions. These electrically conductive regions form a shielding as areal areas or, in the form of strip conductors, a supply or discharge of the high-frequency signals to be transmitted or received.
  • a cable is connected to the ground element 1 designed as a printed circuit board, with which the mobile radio antenna is connected to a downstream electronic device (for example, amplifier, receiver, transmitter or the like).
  • the entire mobile radio antenna is located in a housing, preferably a plastic housing, and has a seal at the point at which the cable is passed through the housing.
  • a feed point 3 and a ground terminal 4 is provided.
  • a printed circuit board, not shown, of the printed circuit board formed as mass element 1 while the ground terminal 4 is connected to a planar-shaped electrically conductive region of the mass element 1.
  • the two antenna elements 2 a, 2 b are separate components or manufactured in one piece, it being particularly advantageous in the case of one-piece design, the two antenna elements 2 a, 2 b, form as a sheet metal part and preferably by means of a stamping process.
  • a sheet metal part has the advantage that it has excellent electrical properties for transmitting and / or receiving high-frequency signals, while the desired shape can be achieved quickly, easily and inexpensively by means of the punch bending process.
  • such a sheet metal part has the advantage that it can easily be electrically connected, in particular soldered, in the region of the feed point 3 or the ground connection 4 to the associated electrically conductive regions of the mass element 1.
  • printed circuit boards with flat, electrically conductive areas are also suitable here.
  • the cable is attached and this unit is inserted into a housing and the housing is closed. Thereafter, the finished mobile antenna is available for use in a vehicle or for attachment to a vehicle.
  • the planar extent of the mass element 1 largely corresponds to the antenna elements 2 a, 2 b, wherein it is conceivable to use more than two antenna elements.
  • the use of a GPS receiver module is also considered, which can be arranged as a finished unit on the mass element 1. In this case, it makes sense, the free surface of the mass element 1 according to the figure for attachment of the GPS receiver module.
  • the semi-oval shape of the antenna element 2a, 2b is particularly advantageous, since they can be arranged at a sufficient distance from the GPS receiver module to reduce or avoid mutual interference in the form of interference radiation.
  • the base plate also from a die-cast.
  • a part of the housing is made of a base plate of a die-cast (for example brass) or in a stamping bending process. Then, this base plate is plane-parallel (coplanar) to the mass element, in particular the circuit board arranged.
  • the attachment is then for example via a screw (in particular by means of a threaded pin on the base plate) or an adhesive bond (in particular a two-sided adhesive film between the underside of the housing of the antenna and the surface of the vehicle component.
