Definitions

  • the invention relates to a directional coupler which can be used for housing installation and is constructed using stripline technology, consisting of two transmission lines, the ends of which are connected to one another and which are attached to opposite surfaces of a dielectric carrier plate.
  • Stripline technology consisting of two transmission lines, the ends of which are connected to one another and which are attached to opposite surfaces of a dielectric carrier plate.
  • Directional couplers designed in stripline technology consist of two strip conductors which are mounted on a surface of a dielectric carrier and run parallel to one another over a certain distance and which, together with the ground back of the dielectric carrier plate, result in two microstrip lines. Between these two Microstrip lines are electrically and magnetically coupled.
  • Such a directional coupler arrangement using microstrip technology shows poor directional sharpness, in particular in the case of high coupling attenuations.
  • DE-AS 21 02 554 discloses a directional coupler designed in stripline technology, one transmission line of which is designed as a microstrip line and the other of which is a slot line.
  • This slot line is formed by a narrow gap which separates the ground conductor surface of the microstrip line and is arranged opposite the strip line of the microstrip line in such a way that the longitudinal radii of the strip line and the gap enclose a small crossing angle which differs from zero.
  • this embodiment however, there are difficulties in the series connection of components and in the transition to a microstrip line.
  • a considerable stray field is created. A transmission down to frequency zero is not possible.
  • the object of the invention is to provide a directional coupler arrangement in planar technology which has a high directional sharpness with a high coupling loss, a high dielectric strength and more. a largely insensitivity of these properties from the housing installation, whereby the additional disadvantages of the directional coupler arrangement known from German specification 21 02 554 are avoided.
  • This object is according to the invention, which is based on a directional coupler of the type mentioned pulls achieved in that the transmission line other than coplanar line is constructed which has a strip conductor inserted on the ground side of the microstrip line in a free from the ground conductor surface area and substantially parallel and approximately opposite f for Stripes enleiter the microstrip line is led.
  • the arrangement according to the invention results in a very low dependence of the directional sharpness on the housing at high coupling attenuations. It is easily reproducible.
  • the coplanar line allows easy series connection of components and a better transition to a microstrip line.
  • the coplanar line also has a smaller stray field than the slot line and, in contrast to this, enables transmission down to zero frequency.
  • a stripline 2 and 1 is on one surface of a carrier plate 1 made of dielectric material a ground conductor surface 3 is attached to the other surface.
  • the strip conductor 2 and the ground conductor surface 3 together form a microstrip line.
  • an area 4 is excluded from the ground conductor surface 3, in which a further strip conductor 5 is guided, which together with the ground conductor surface 3 forms a coplanar line.
  • the free area 4 is bridged at one point by means of a ground bridge 6.
  • the outcoupled wave is available at a coupling point 11 of the stripline 5 of the coplanar line.
  • FIG. 3 shows a variation with a meandering of the coplanar coupling line. Otherwise, the directional coupler arrangement according to FIG. 3 corresponds to that according to FIGS. 1 and 2, so that the reference symbols are adopted. It is equally good to meander the microstrip line, i.e. the stripline 2 possible.
  • FIG. 4 Another embodiment is shown in FIG. 4.
  • a triplate line structure is used as the main line.
  • the coupled coplanar line with its stripline 12 is easily accessible on one of the outer surfaces of the triplate line.
  • the strip conductor 13 of the triplate line is here guided between the two ground conductor surfaces 14 and 15 of the two assembled dielectric carrier plates 16a and 16b.
  • the coplanar line like the strip conductor 13 of the triplate line, can be meandered or sawtooth-shaped.
  • Broadband directional couplers can be formed by coupling couplers according to the above-described embodiments with different coupling attenuations and different coupling lengths in the manner of a cascade connection.
  • FIG. 5 shows a cross-sectional view of a directional coupler arrangement, mounted on a dielectric carrier plate 16, for coupling a microstrip line, consisting of a strip conductor 17 and the ground conductor surface 18, to two mutually independent coplanar lines, the strip lines 19 and 20 of which are in two free areas the ground conductor surface 18 are.
