  • Applicant's European patent EP 1 024 552 A2 discloses a multi-band antenna which has already been improved in terms of manufacturing costs and space requirements. This improvement has been achieved by combining the multi-band antenna with several different types of antennas, all fed at one point. As a result, both the manufacturing costs and the space required by the antenna can be reduced.

  • the MID method allows the production of finer antenna structures compared to the punch bending technique.
  • the new multiband antenna arrangement also allows various types of coupling between the planar patch antenna and the parasitic radiators to be realized. Due to the nature and strength of the coupling, either the bandwidth of a resonance already generated by the antenna patch can be increased or an additional resonance can be added.

Abstract

L'invention concerne un ensemble antenne multibande destiné à des appareils de téléphonie mobile et comprenant une antenne à plaque plane (1) qui présente au moins deux résonances (1.1 et 1.2) et dispose d'une liaison à la masse (1.M) et d'une liaison haute fréquence (1.RF), ainsi qu'au moins deux éléments rayonnants parasites (2.1, 2.1' et 2.2), placés en bordure de l'antenne à plaque plane et réalisés respectivement sans liaison haute fréquence. L'invention est caractérisée en ce que, grâce à l'agencement particulier de l'antenne à plaque plane (1) et des éléments rayonnants parasites (2.1, 2.1' et 2.2), on obtient une antenne multibande pour plusieurs bandes de fréquence qui a une structure particulièrement compacte.
