Definitions

  • the invention relates to a radio of the type described in the preamble of claim 1.
  • the rod antennas of compact radio devices can generally be retracted or retracted. If the device is to remain ready for operation in this state (standby mode), an antenna (auxiliary antenna) integrated in the device must be provided in addition to the rod antenna (main antenna), since the recessed or folded main antenna is strongly detuned and at least partially shielded and therefore unusable is.
  • auxiliary antenna integrated in the device
  • main antenna rod antenna
  • Known solutions with an integrated antenna have the disadvantage that the latter interferes with the function of the main antenna by removing energy from it. Conversely, the main antenna interferes with the function of the integrated auxiliary antenna when it is sunk.
  • Another disadvantage is that the integrated auxiliary antenna requires a not inconsiderable installation volume.
  • the invention has for its object to eliminate the disadvantages listed above and to provide a compact radio with integrated auxiliary antenna, which enables standby operation with the rod antenna retracted or folded down, the mutual interference of the auxiliary antenna and rod antenna being as small as possible should.
  • the handheld radio shown in FIGS. 1 and 2 which is denoted overall by 1, has a rod antenna 2 functioning as the main antenna, at the base of which there is a feed part 3.
  • the upper end region of the antenna 2 consists of an insulating part 4.
  • the antenna 2 can be sunk with its feed part 3 in a receiving space 5 provided in the handheld radio 1.
  • This recording room 5 opens with its upper end region in a conical housing extension 6, which is made of plastic.
  • This conical extension 6 is hollow, so that the feed part 3 of the antenna 2 is received in it when the antenna 2 is pulled out completely.
  • An integrated auxiliary antenna 7 is embedded in the material of the attachment 6, which is designed in a helical or meandering shape and is mechanically and electrically decoupled from the radio (for example by design as a half-wave radiator).
  • the feed point of the integrated antenna 7 is designated 8.
  • the connection between its feed part 3 and its feed point denoted by 9 is interrupted.
  • the device is switched to the integrated antenna 7.
  • the integrated antenna 7 is not disturbed by the inserted rod antenna 2, since its upper end area 4 consists of insulating material.
  • the integrated antenna 7 is detuned by the spatial proximity of the antenna radiator or base point so that it cannot exert any disruptive influence.
  • the integrated antenna designated 7 ' serves as an electrical adapter for the main antenna 2'.
  • the feed part 3 connected to the lower end region of the antenna 2 of FIGS. 1 and 2 can be omitted.
  • the feed takes place in the device of Figure 3 via a z. B. formed as a transformer feed element 10, which is provided for the integrated antenna 7 'and the rod antenna 2' together.
  • the rod antenna 2 ' is pulled out, its base point is capacitively or galvanically coupled to the upper end of the integrated antenna 7'.
  • the integrated antenna 7 ' discontinues to radiate when the rod antenna 2' is extended, this results in a less favorable radiation diagram and a less large antenna gain, in contrast to the embodiment in FIGS. 1 and 2.
