  • the coupling element 40 is provided so that an important portion of the coupling element 40 is situated near to a second end of the first antenna element 20 which is opposite to the first end where the first connecting means 50 are situated.
  • the antenna arrangement 5 is provided so that there is a relatively large coupling area where the coupling element 40 and the second end of the first antenna element 20 are fairly close to each other.
  • the interaction of the antenna arrangement 5 with radio frequency radiation implies that the very narrowly spaced surfaces of the coupling element 40 and of the second end of the first antenna element 20 have the effect of a capacitive coupling between the first antenna element 20 and the second antenna element.
  • the capacitive coupling between the two antenna elements is therefore provided like the coupling between the two plates of a condensator.

This distance is equal to the distance of the first antenna element 20 and the ground plate 10.
  • the bent end of the first antenna element 20 connects the first antenna element 20 to the ground plate 10 and forms the first connecting means 50 in a bridge-like manner. So, the first connecting means 50 are provided as a connecting bridge.

This distance is less than the distance between the first antenna element 20 and the subelements 30, 31.
  • the antenna arrangement 5 as it is described is operational with at least two different frequency bands.
  • the exact value of the center frequency and the band width of the frequency bands is dependent on the dimensions and the shapes of the first antenna element 20, the second antenna element and the kind of coupling between these two antenna elements.
  • the antenna arrangement 5 can be used to emit radio frequency radiation which means that the radio apparatus 1 is used as a transmitter.
  • the antenna arrangement 5 can be used as a reception antenna which means that the radio apparatus 1 can be used as a receiver. It is also possible to use the antenna arrangement 5 both, as an emitting antenna, and as a receiving antenna, and likewise the radio apparatus 1 as a transceiver.
  • the antenna arrangement 5 according to the invention is very flexible concerning the tuning to particular frequency bands of operation. This feature is combined with the fact that the radiation not only originate from one point or a single part of the antenna arrangement but from several parts of the antenna arrangement 5. Analogously, for the receiving mode of the antenna arrangement 5, radiation is not only incident to one point or to a single part of the antenna arrangement 5 but to several parts of the antenna arrangement 5.

  • the antenna arrangement 5 can be placed and shaped mechanically in order to obtain a large tolerance to, for example, the finger of an operator held very close to the antenna element 5.
  • the center frequencies and the band widths of the frequency bands of operation of the antenna arrangement 5 are also dependent on the coupling scheme provided by the second end of the first antenna element 20 and by the coupling element 40 of the second antenna element.

For example, there can be corners cut out of elements or corners can be provided round, rectangular parts can be shaped differently and do not to be flat, and especially different coupling scenarios can be applied, which can be described as coupling schemes between the free end of the first antenna element 20 and the coupling element 40 mixing the coupling schemes described in the figures.
  • the subelements 30, 31 of the second antenna element can be provided in another plane than the second plane. This other plane can be parallel to the ground plate 10 or it can be inclined. This means that it is possible to provide these subelements 30, 31 at a different distance from the ground plate 10 than the first antenna element 20. It is possible to provide one of the subelements 30, 31 in another plane, i.e. at another distance of the ground plate 10 than the other of the subelements 30, 31. Furthermore, it is also possible to provide a capacitive coupling between the ground plate 10 and one of the subelements 30, 31 or all of the subelements 30, 31 in order to lower the dimensions of the subelements 30, 31 needed for a given frequency of operation.
  • This capacitive coupling can be provided, for example by lowering the distance between the ground plate 10 and the subelements 30, 31 or by providing a discrete capacitor between the ground plate 10 and the subelements 30, 31. Furthermore, it is possible that the subelements 30, 31 are provided with different length so that one of the subelements 30, 31 is operational at a different frequency of operation than the other subelement 30, 31. These different frequencies can be provided in different frequency bands in order to operate the antenna arrangement 5 in three or more frequency bands.
