Definitions

  • the present invention relates to a multiband antenna.
  • Previous radio-operated communication terminals are generally characterized by the fact that they have an antenna that cannot be integrated into the device. They have a more or less large stub at the top of the device, in which e.g. a helix antenna or a printed circuit board serving as an antenna.
  • this stub is rejected for design reasons.
  • the stub can also interfere with carrying the mobile phone in your pocket.
  • the dimensions of the devices are getting smaller and smaller, which is an additional problem for the antenna design, since the space available for the antenna is also limited.
  • the object of the present invention is to provide an antenna of the type mentioned at the outset which has no stub, can be integrated in the communication terminal housing and has the required dual-band capability.
  • the antenna mentioned at the outset consists of a metallic, essentially rectangular overall surface lying above a ground surface and connected to one or more supply and ground contacts, which has a long surface for radiating two independent frequencies has an outer path for a low resonance frequency and a roughly rectangular inner structure for a higher resonance frequency.
  • the antenna according to the invention can be easily integrated into a small communication terminal and is easy to manufacture.
  • the dual-band capability of the antenna according to the invention is achieved in that it is essentially a combination of a patch-inverted-F antenna (PIFA) for the GSM band ( ⁇ / 4 resonance) and a patch antenna for the PCN -Band ( ⁇ / 2 resonance).
  • PIFA patch-inverted-F antenna
  • the fact that the different bands use the same geometrical areas of the antenna means that the antenna requires very little space.
  • FIGS. 1 to 6 show different specific exemplary configurations of a multiband antenna that can be integrated according to the invention.
  • FIGS. 7 and 8 schematically show the basic design options of the multiband antenna according to the invention.
  • the structure of the antenna according to the invention will first be described with reference to FIG. 1.
  • the large area FI and the path P running along the outside of the circumference roughly represent the PIFA antenna for the GSM band. This, in order to be properly adapted, requires a ground contact M.
  • the same area FI and the notched rectangular area F2 located in the interior of the antenna approximately represent the patch antenna for the PCN band. An almost arbitrary shape of this area would be conceivable.
  • the triangular notch results in a lower resonance frequency.
  • the notch achieves a wider range than with a purely rectangular structure.
  • the two antenna areas can be tuned almost independently of one another by the outer path, i.e. the outer frame or the circumference of the antenna or the lower edge is lengthened or shortened, which leads to a displacement of the two bands or increases or decreases the inner surface, which only influences the PCN band.
  • Another way of influencing is to choose the connection location of the ground contact.
  • FIG. 2 shows a variant of the antenna of FIG. 1, which has its origin in the fact that it is generally favorable for the antenna properties if the leads are made via short wires. If the available contact point for the supply is unfavorable, the antenna shape can be adjusted accordingly.
  • FIGS. 3 to 6 show further possible antenna shapes.
  • the antenna need not be rectangular, but can also have curved shapes in order to be better integrated into an existing housing. It is also possible that the antenna is not made purely planar, but has areas with different heights and slopes.
  • the part responsible for the higher frequency can also have any other shape and can also be galvanically coupled at other points (for example on the right edge of the antenna, see FIG. 6, depending on the required resonance frequency).
  • the path running outside can also be made thicker or thinner. Furthermore, the path does not have to have a constant width, as can be clearly seen in FIG.
  • the structural dimension required for the electrical length of the PIF antenna (low frequency) can be rotated around the circumference as desired. This results in an imaginable structure division according to FIGS. 7 and 8, the position of the feed or ground contacts being arbitrary on the
  • Structural elements can be positioned (see in particular Figure 8).
  • the ground plane does not have to be planar either. It can also be structured or curved, so that it is possible to position the antenna, for example, via a screen cover.

Abstract

L'invention concerne une antenne qui est constituée d'une surface pratiquement rectangulaire, métallique, s'étendant sur une surface de masse et reliée à un ou plusieurs contacts d'alimentation et de masse. Ladite surface présente, pour l'émission selon deux fréquences indépendantes, un long chemin extérieur, pour une fréquence de résonance basse, et une structure intérieure grossièrement rectangulaire, pour une fréquence de résonance plus élevée.
