Definitions

  • the invention relates to a multiband antenna with the generic features of claim 1.
  • multiband antennas are required that cover different frequency ranges, e.g. to be able to improve network utilization and roaming at home and abroad.
  • the antennas should also be able to be designed for a broadband frequency range.
  • these antennas should have only small dimensions and a low weight.
  • this antenna must be cheap and reproducible to manufacture.
  • Multiband antennas are known in which a plurality of conductor tracks are arranged as radiation bodies on at least one side of a printed circuit board. Only one of the conductor tracks is connected to a transmitter / receiver or e.g. designed as a simple radiating element. Other conductor tracks are not connected directly via electrical conductors, but are designed in such a way that they are excited by an electromagnetic coupling. In particular, the coordination of the conductor tracks is very difficult and complex.
  • Microstrip line antennas require a ground plane that completely covers the back of a printed circuit board (PCB). The required distance from the radiating elements also requires a large amount of space. These antennas are also expensive to manufacture.
  • PCB printed circuit board
  • Multi-layer PCB multiband antennas are more complex to manufacture and have a lower reproducibility.
  • the known systems are also disadvantageous in terms of their ability to be removed, since a large amount of time is required in the development due to a large number of time-consuming work steps.
  • the punching and bending technique and the wound helix require simulations, and the implemented result usually has to be corrected again, since simulation and practice generally do not match sufficiently.
  • the punching and bending technique also means that changing the tool takes longer or, in extreme cases, may not even be possible in the final stage.
  • Multi-layer antennas with more than two layers have the disadvantage that they cannot be easily etched in many laboratories, since the technology is not available in-house and the tests have to be carried out with the supplier.
  • the object of the invention is to propose an improved antenna with multi-band capability.
  • the proposed antenna is ideally a multiband antenna that can cover different frequency ranges, so that the utilization of the networks and the roaming in and
  • a further downsizing of the mobile radio devices is also made possible, since the dimensions of the antennas and their weight can be reduced. In particular, a reduction in the total height required is possible.
  • these antennas can be produced inexpensively, since only two conductor tracks are required, for example, in the case of an antenna for two frequencies. In addition, no mass is required, which further simplifies the construction.
  • Such antennas are also easily reproducible due to low tolerance fluctuations in production. It is particularly advantageous that such an antenna can be tuned particularly easily in a wide variety of ways. In particular, a short-term fine-tuning of the antenna is also possible.
  • An antenna can be set up at short notice in your own laboratory, e.g. in half a day, including etching or milling the structure if necessary. The data can then be passed on to the circuit board manufacturer, who then also quickly, e.g. creates a new mask within one day, without implementation problems, with which mass production can then be started. It is also possible to carry out additional tests on this basis.
  • the combination of a two-level PCB antenna with one or more vias and / or one or more face contacts is particularly advantageous. This combination extends and simplifies the possibilities of coordinating the overall arrangement. This makes it possible to provide a particularly space-saving, cheap and relatively easily tunable multiband antenna.

  • an exemplary two-level PCB multiband antenna consists of a carrier in the form of a printed circuit board 1, which is shown transparently here apart from its outer contours.
  • the circuit board 1 carries one or more structured conductor tracks 2 and 3 on both sides.
  • the conductor track 2 can be connected to a transmitting / receiving circuit via a contact surface 12.
  • the conductor tracks 2 and 3 are electrically connected here directly. As a result, they represent one or more electrical radiators that resonate at two or more frequencies.
  • the resonance frequencies can be freely selected by choosing the location of the electrical connection, that is to say the connecting points of the conductor tracks 2 and 3, and by selecting the arrangements and shapes of the conductor tracks 2 and 3.
  • the conductor tracks 2 and 3 of the two levels are thus directly connected in an electrically conductive manner via one or more edge and / or end face contacts 4.
  • contacting can also take place at one or more points through the printed circuit board 1, as is the case here for example in Fig. 2 is shown with a via 6.

  • a combination of direct connections and couplings between the front and rear sides and also couplings to further interconnects 10 which are formed via the gaps 9 and are not directly connected can be produced.
  • Two or more radiators can also be attached to the back, which are excited by coupling both from the front and from the back. Examples of a multitude of further possible combinations are shown in FIGS. 5 and 6.
  • An antenna can in particular also be constructed from a plurality of printed circuit boards 1, each with one or more conductor tracks and / or printed circuit boards with one or more conductor tracks, on one or more layers in such circuit boards, which can be arranged in any way relative to one another.
  • the individual layers and / or printed circuit boards are preferably, but not necessarily, parallel to one another.
  • the Distance between the levels can also be used as an option for coordination.
  • circuit board material is freely selectable, but should be suitable for high frequencies, e.g. commercial circuit board material FR4 or a flexible plastic material, in particular a film made of polycarbonate or polyetherimide. Individual conductor tracks can also be included in the material.
  • Such an antenna can advantageously also be integrated directly into a main assembly.
  • Branch lines can also be implemented on the antenna PCB itself.
  • one or more matching circuits can be arranged on the antenna carrier itself and not only on the main assembly.
  • the provision of other assemblies, in particular electronic elements, is also possible on such a printed circuit board, such elements optionally also being able to communicate with the conductor tracks, e.g. can be actively controlled by the signals on the conductor tracks or in turn can influence or specify the signals on the conductor tracks.

Abstract

L'invention concerne une antenne, en particulier une antenne multibande pour appareils radio mobiles, qui comprend un support (1) à plusieurs faces et au moins deux pistes conductrices (2, 3) en tant que dispositif d'émission et/ou de réception, situées dans divers plans du support (1). Dans l'antenne selon l'invention, au moins deux des pistes conductrices (2, 3) sont reliées par un élément de mise en contact (6) direct. L'antenne se présente, de façon idéale, sous la forme d'une antenne multibande pouvant couvrir différentes gammes de fréquences, de telle sorte que l'utilisation des réseaux et l'itinérance nationale et internationale sont améliorées. On peut avoir ainsi une conception simple offrant un fonctionnement dans plusieurs bandes de fréquences. En particulier, un accord fin rapide de l'antenne est possible. Les possibilités d'accord des différentes pistes conductrices sont, en particulier avec une combinaison de pistes conductrices mises en contact et d'autres pistes conductrices couplées, optimisées.
