Definitions

  • the invention relates to an arrangement for symmetrical dining or several dipoles arranged in front of a reflector surface over one unbalanced stripline.
  • Balancing transformer can be manufactured using stripline technology, whereby the Center conductor of the unbalanced stripline between two at a distance stripline pairs arranged from one another is routed in the middle (British Patent specification GB 2089135 A, Fig. 2).
  • This central conductor strip ends between the second pair of strip conductors without connection, the symmetrical away from it Stripline leading to the dipoles is with the top stripline of the first Stripline pair and the lower stripline of the second Stripline pair connected.
  • the feed arrangement according to the invention is a galvanic electrically conductive contact between the Stripline of the asymmetrical stripline and the dipole is superfluous, the stripline ends without a connection.
  • the two dipole halves are over connection strips only with the two additional ones at an axial distance insulated from each other on the conductor strips
  • Conductor parts galvanically connected and these parts can therefore very easy and cheap by punching and bending be made from a piece of sheet metal, additional galvanic joints by soldering, screwing or the like become superfluous.
  • An inventive Dining arrangement is therefore not only very simple and inexpensive to manufacture, but also extremely reliable, failure due to bad contacts is impossible.
  • the feed arrangement according to the invention is suitable also suitable for feeding from several to groups summarized dipoles, e.g. to increase the Antenna gain can be used.
  • Fig. 1 shows a perspective view of an inventive Feed arrangement
  • Fig. 2 shows the associated Cross-section along the section line I-I.
  • Fig. 1 shows one consisting of two dipole halves 1 and 2 Dipole in the shown embodiment is designed as a half-wave dipole. This dipole could also be designed as a full-wave dipole, the two Dipole halves 1, 2 can also have different lengths have and have any cross-sectional shape.
  • This two dipole halves 1, 2 are at a distance 3 before one for the sake of clarity only fragmentary in Fig. 1 shown reflector surface 4 arranged.
  • the two dipole halves 1, 2 are at the upper ends of two spaced apart and parallel to each other arranged terminal strips 5, 6 attached by an opening 7 of the reflector 4 up to the rear extend and the symmetrical feed line for form the dipole 1, 2.
  • the terminal strips 5, 6 are preferably in one piece with the dipole halves 1, 2 punched out and bent into a piece of sheet metal. Which opposite conductor surfaces of these two connection strips 5, 6 and their distance is chosen so that about the wave resistance thus formed between the two dipole halves 1, 2 existing dipole impedance on one of their connection ends ending behind the reflector desired output impedance transformed becomes.
  • On the connecting strips 5, 6 can for this purpose over part or all of the length Sheet metal bends can be provided for an extended To reach the range of the impedance transformation.
  • connection to the transmitter or receiver is made in the exemplary embodiment shown via a strip line, which in the further course into another type of line, e.g. a coaxial cable.
  • the stripline is paralleled by a distance between the reflector surface 4 and one parallel to the reflector arranged rear wall 30, for example a supporting mast guided strip line 8 formed.
  • On this stripline 8 are two U-shaped in cross section Conductor parts 9 and 10 placed so that they according to the sectional view of FIG. 2, a distance on all sides own of the stripline 8.
  • the strip conductor 8 are the two conductor parts 9, 10 immediately below the opening 7 of the reflector 4 arranged at a distance 11 from each other.
  • each ⁇ / 4 chosen so that their Impedance to that due to the balanced line 5, 6 transformed dipole impedance is high.
  • reflector surface 4 or rear wall 30 formed a kind of pot circle.
  • the U-shaped curved conductor parts 9, 10 with their Connection flanges 14, 14 ', 15, 15', the branches branching therefrom Terminal strips 5, 6 and the dipole halves 1, 2 are preferably cut in one piece from sheet metal and bent accordingly, they will be including the Dipole halves 1, 2 through the flange fastenings 14, 14 ', 15, 15 'on the reflector 4 or the rear wall 30 mechanically held. If necessary, the conductor strip 8 mechanically by means of one or more dielectric supports be supported, otherwise all parts are in theirs predetermined distance from each other electrically by air isolated.
  • the width 17 of the U-legs of the two conductor parts 9, 10, their mutual distance 18 and the width and thickness of the strip line 8 and also the axial length of the Conductor parts 9, 10 are chosen so that the determined wave resistance and the resulting frequency-dependent impedance on the two conductor parts High frequency currents - indicated by the current arrows 19 and 20 - are forced on the opposite Junction points 12, 13 of the connecting strips 5, 6 of the Dipole feed line are each the same size, so that on the connecting strips 5, 6 correspondingly the same size opposite phase feed currents 23, 24 and thus corresponding equally large rectified currents 25, 26 on the Dipole halves 1, 2 flow.
  • the stripline 8 If on the side opposite the reflector 4 the stripline 8 no additional rear wall 30 as Partial return line is provided, the lower U-legs of the conductor parts 9, 10 are omitted, the conductor parts are then only narrow strips of metal that arranged between reflector 4 and stripline 8 are and at their ends with the connecting strips 5, 6th or via the bends 14, 15 with the reflector 4 are connected.
  • omnidirectional antennas can also be used be built, where also lateral reflector surfaces are provided.
