Definitions

  • the invention relates to an antenna for receiving meter waves in motor vehicle windows with a meat-like frame in the form of an essentially vertical unipole in the region of the vertical window center.
  • the antenna With antenna structures in vehicle windows, it is known that it is possible to receive all wave bands (e.g. LMK and VHF radio) with good performance. It is advantageous that the antenna, due to the integration into the vehicle body, meets vehicle-specific requirements such as mechanical robustness, long service life, easy installation and avoidance of unnecessary air turbulence much better than the standard rod antenna.
  • wave bands e.g. LMK and VHF radio
  • the invention is based on an antenna with very good suitability for frequencies in the FM range, as is known from P 2136 759.
  • This antenna uses a unipole in a metallic frame, e.g. is formed by the frame of a vehicle window, the Unipol in this special application being applied to the glass window located therein.
  • Such an antenna has excellent reception properties both for horizontally polarized waves and for vertically or circularly polarized waves and, in the embodiment according to the invention, delivers average signal levels which are almost equivalent to those of a passive telescopic antenna, as is customary for vehicles.
  • the object of the invention is to incorporate a heating field of the usual type with horizontal heating conductors in an antenna of the generic type such that the antenna achieves a high sensitivity regardless of the polarization of the receiving field of the meter waves in the receiver.
  • the advantages that can be achieved with the invention consist in the excellent reception powers of the antenna thus formed for horizontally and for vertically or circularly polarized waves in the meter wave range, while at the same time largely uncritical dimensioning with regard to the required ones Number of ancestors, their distance from each other and the total height of the structure. From the point of view of the technological requirements, it is particularly advantageous that the same technology is used for the realization of the antenna conductors and the heating conductors, both types of conductors being applied to the pane in the same working process in the screen printing process or with wires inserted between the layers of a laminated glass pane. can be introduced. These aspects are the prerequisite for an extremely cost-effective implementation.
  • the galvanic connection of antenna conductors and heating conductors also has the advantage with printed conductors that no further contacting is required during the galvanizing process, as is the case with antennas without a galvanic connection.
  • the metallic frame (21) which represents the body of the vehicle, encloses a vehicle window (34) on which a structure of horizontal heating conductors (2), the heating conductor being on the border between the 1st area (40) and the 2. Area (41) is arranged, which carries the designation (38).
  • these horizontal heating conductors are either printed on the surface of the vehicle window using the screen printing process and then galvanically reinforced in order to achieve a low-resistance value required for heating purposes or, in the case of vehicle windows made of double-pane laminated glass, between the two glass windows, e.g. in the form of tungsten wires.
  • the heating conductors (2) are wire-shaped.
  • the area of a vehicle window covered by the heating field is usually large, so that only comparatively narrow strips remain above and below the heating field, the dimensions of which do not allow the realization of antennas for the meter wave range with the good properties specified in P 2136 759.
  • the antenna conductors (11) overlap with the horizontal heating conductors (2) or (38) in the manner shown in the first area (40) with the horizontal dimension (4) and the vertical dimension ( 6), where (7) is the vertical dimension of the heating field. It is essential for an antenna according to the invention in the first area (40) that, among other things, there is a galvanic connection at the crossing points (35) between the horizontal heating conductors (2) and the antenna conductors (11).
  • these vertical antenna conductors (11) represent undesirable shunts, via which equalizing currents can flow between the individual horizontal heating conductors (2), as a result of which the defrosting properties of the heating pane are undesirably changed.
  • this is avoided in that the antenna conductors (11) the horizontal heating conductors (2) in one Cross in such a way that the individual crossing points each lie on one of the antenna conductors (11) and the cut horizontal heating conductors (2) on equipotential lines (37) with respect to the DC voltages of the heated pane in accordance with FIG. 2, so that no compensating currents flow in the antenna conductor (11) .
  • the line of symmetry (3) of the pane represents such an equipotential line, along which exactly half the voltage of the on-board battery (36) is present when the heating is switched on relative to the frame.
  • Fig. 2 shows further equipotential lines (37).
  • the equipotential lines are not exactly parallel to each other, whereby the deviation from the parallelism with respect to the equipotential line in the center of the pane is greater towards the edge of the pane, and the more pronounced the trapezoidal shape of the pane is compared to a rectangle. If the antenna conductors (11) are consequently arranged only in a sufficiently narrow area around the vertical line of symmetry of the disk (3), the parallel arrangement of the antenna conductors (11) can be used as a good approximation to the equipotential lines.
  • one end of the antenna conductors (11) is galvanically connected to the horizontal heating conductor (38) forming the end of the heating field, so that the 1st area (40) and the 2nd area (41) are immediately adjacent.
  • each of the antenna conductors (11) crosses at least one further heating conductor (2).
  • 6 of a total of 9 horizontal heating conductors (2) or (38) are crossed.
  • the number of antenna conductors (12) in the second area (41) can fundamentally differ from the number of antenna conductors (11) in the first area (40), as shown in FIG. 1, in which there are three antenna conductors (12) . These begin at the heating conductor (38) forming the edge of the heating field, to which they are galvanically connected, and end at the merging antenna conductor (10), to which they are connected with low impedance for the frequencies of the useful frequency band within the meter wave range.
  • all antenna conductors (11) and (12) for an antenna according to the invention are arranged in an area (42) of half the central pane width (5) symmetrical to the line of symmetry (3) of the pane (Fig. 2).
  • the assessment of the performance of the respective antenna according to the invention with a variation in the arrangement and the number of antenna conductors (11) and (12) is carried out in practice using known, statistically evaluating, computer-aided measurement methods which determine the antenna output level with the aid of a measurement receiver, and in which test drives are carried out in typical reception fields with the respective to investigating frequency and polarization of the incident wave, the mean signal levels and the level statistics of the test antenna are determined in comparison to a reference antenna.
  • the simplest arrangement of the antenna conductors for an antenna according to the invention consists in each case of a single vertical conductor (11) in the 1st area and (12) in the 2nd area, which merge directly into one another.
  • the merging antenna conductor (10) degenerates in this special case to the connection point (8), from which the further antenna conductor (22) essentially parallel to the two narrow sides of the frame, that is along the line of symmetry (3) to near the frame to Coupling point (23) leads and represents the direct continuation of the antenna conductor (12) (Fig.3).
  • the pane opening enclosed by the conductive frame (21) is to be regarded approximately as a slot radiator which is optimally excited by a wave with an electrical field strength vector oriented in the direction of the vertical line of symmetry (3) of the pane.
  • the pane width corresponds to approximately half a wavelength, as is usually the case in today's cars in the middle of the frequency range of the meter waves, there is also a resonant increase in the electrical fields in the center of the pane.
  • the signal decoupled from the Unipol only slightly decreases at the beginning, but quickly decreases with increasing proximity to the edge of the pane if it is attached asymmetrically.
  • the reception powers consequently become poorer, so that this unipole will preferably be arranged in the central region of the disk in an antenna according to the invention.
  • the unipole may also be necessary and sensible to arrange the unipole asymmetrically to the line of symmetry (3) in the disk. Stylistic aspects may make this necessary or the need to use several antennas according to the invention with different reception behavior, e.g. for antenna diversity systems or for different partial frequency ranges of the meter wave range in a vehicle window.
  • the unipole can be moved to the edge of the area (42) without loss of the essential properties of the antenna, which is arranged symmetrically to the line of symmetry of the disk and the width of which is as large as possible is half the average slice width.
  • each of the conductors in the disk represents a line with a high impedance and high losses compared to conventional coaxial lines.
  • Fig. 4 exemplifies the particularly effective part of the entire conductor structure of Fig. 3 to illustrate this property of the decoupling.
  • This decoupling which increases with the distance from the decoupling point (23), makes the good-natured behavior of an antenna according to the invention understandable with regard to changes in the number of antenna conductors and the geometry if these changes are carried out at a sufficient distance from the decoupling point.
  • the antenna conductor (11) no longer crosses all 9 heating conductors (2) or (38) of the heating field, as shown in FIG. 3, but, for example, how shown in Fig.5, only the 5 heating conductors of a partial heating field crosses.
  • the good reception performance of an antenna according to the invention is essentially retained as long as at least two heating conductors are crossed.
  • the number of crossed heating conductors is preferably chosen to be greater than 2, as a rule as a result of this there are no other disadvantages and the reception properties tend to improve.
  • Stylistic aspects also suggest choosing the length (6) of the antenna conductor (11) as large as the height of the heated surface (7), if not, for example, the need for further independent antennas in the pane, as shown in FIG to realize is given.
  • An advantageous embodiment of an antenna according to the invention further consists in using two or more antenna conductors (11) and (12) in the 1st and 2nd area.
  • the zone which is preferably effective for reception can be widened, as will be explained below with reference to FIGS. 6 and 7.
  • FIG. 7 shows an example of the area that preferably contributes to reception in the unipole structure according to FIG. 6.
  • (56) is selected in the range between 1/30 and 1/10 of the operating wavelength, there is a particularly efficient broadening of the preferably effective reception zone. If you choose the distance (56) smaller than the above, the effect is almost identical to that of a single antenna conductor, if you choose the distance (56) larger than the above, there is no further advantage. If the structure width (4) or (9) is greater than 1/10 of the operating wavelength, the use of additional antenna conductors is recommended.
  • a structure according to FIG. 6 again delivers somewhat better reception powers than the structure according to FIG. 3 because of the wider, preferably acting reception zone.
  • it has the further advantage that if one of the two conductor lines is interrupted, the reception power drops, but only to an extent that is hardly noticeable in practice, whereas in the case of a structure according to FIG ) the reception gets significantly worse.
  • the use of more than two antenna conductors (11) and (12) for an antenna according to the invention is in no case harmful, but due to the decoupling described above, the effect of an increase in reception power becomes smaller the further the newly introduced antenna conductors from Decoupling point (23) are removed.
  • the area (42) within which the conductors (11) and (12) are to be arranged can therefore be specified as the upper limit for a sensibly designed unipole for an antenna according to the invention.
  • the low-impedance connection of the antenna conductors (12) by the merging antenna conductors (10) takes place by means of a galvanic connection.
  • Such a galvanic connection through the merging antenna conductor (10) leads to a shunt for the heating current through the antenna conductor (12) in combination with the merging antenna conductor (10).
  • the current in the heating conductor (38) is particularly affected due to the spatial proximity. The situation for this heating conductor (38) is explained in more detail below with reference to FIG. 8, which represents a section from FIG. 1 for the area of the pane center in the vicinity of the heating conductor (38).
  • the heating current (46) is divided into portions (47) and (48), the ratio of which, in a known manner, from the ohmic partial resistors (53) and (54) on the two current paths between the branching point ( 45) and the merging point (50) is determined, as shown by the electrical equivalent circuit for the current branch in FIG. 9.
  • the respective partial resistance is proportional to the respective path length between (45) and (50). Due to the fact that an equipotential line lies in the symmetry line of the structure, the current (49) in FIG. 8 is basically zero and therefore no longer needs to be considered in the following.
  • the effect of the length of the current paths on the ratio of the currents (47) and (48) and on the heating power between points (45) and (50) will be considered approximately.
  • the geometry of FIG. 8 is to be assumed, in which the antenna conductors (12) are exactly parallel to one another and each have exactly the same length, so that the antenna conductor (10) bringing together has the same length as the distance between (45 ) and (50).
  • the introduction of the current path via the antenna conductor (12) and the merging antenna conductor (10) does not change the total current (46).
  • the following considerations can be applied analogously to deviating geometrical arrangements.
  • the two ohmic resistors (53) and (54) are of the same size and the two currents (47 ) and (48).
  • the total resistance between points (45) and (50) is therefore half the resistance that would be effective in the absence of the antenna conductor (12) and the merging antenna conductor (10) if the cross-section of the two conductors in the area under consideration is not adjusted.
  • the heating of the disc between the Points (45) and (50) is at a small distance between antenna conductor (12) and merging antenna conductor (10) because of the proportionality of the converted active power to the total resistance (55), which results from the parallel connection of (53) and (54) , also only half as large as in the absence of the antenna conductor (12) and the merging antenna conductor (10).
  • there is consequently a defrosting behavior which deviates from the rest of the heating field in the area between points (45) and (50).
  • the conductor cross section of the conductor (38) between the points (45) and (50) and the merging antenna conductor (10) is therefore cut in half more advantageously for an antenna according to the invention, a measure that is easily possible in the case of conductors printed in the screen printing process by a corresponding design of the sieve is.
  • the length (52) of the antenna conductor (12) is no longer so small that the pane in the area between the points (45) and (50) is heated as if by a single conductor, the relationships are more complicated. As a rule, one will be interested in limiting the heating of the pane to the area around the heating conductor (38) and consequently striving for a dimensioning in which the heat converted via the antenna conductor (12) and the merging antenna conductor (10) remains low . This goal can be achieved by a corresponding choice of the cross sections of the antenna conductors (12) and the merging antenna conductors (10) on the one hand and the section of the heating conductor (38) between points (45) and (50) on the other hand for an antenna according to the invention.
  • the ratio R2 / R is therefore determined according to this table for a predetermined ratio R1 / R by choosing a suitable conductor cross section in the area of the antenna conductor (12) between points (45) and (50), that is in the area the structure width (9).
  • a suitable conductor cross section in the area of the antenna conductor (12) between points (45) and (50) that is in the area the structure width (9).
  • the DC resistance must be doubled in accordance with the table, which is advantageously achieved by reducing the cross-section by half.
  • a further advantageous embodiment of an antenna according to the invention without cross-sectional adaptation is possible if the strip available between the heating conductor (38) and the frame in the special vehicle window is so large that the length (52) of the antenna conductor (12) is large compared to the width ( 9) the structure in the second area (41) is selected.
  • the ohmic resistance (54) is so large compared to the ohmic resistance (53), so that the current (47) almost corresponds to the current (46) and the current (48) is negligibly small. In the table above, this corresponds to very high values of R1 / R, for which R2 / R asymptotically approaches the value "1".
  • the antenna according to the invention it is advantageous for the antenna according to the invention to arrange the merging antenna conductor (10) as close as possible to the frame, because in this way influencing the direct current flow and thus the distribution of the heating power on the pane is the most favorable.
  • the problems explained above are avoided in that, like galvanic connection, the antenna conductor (12) is replaced by the merging antenna conductor (10) by a connection which has no direct current passage, but for the frequencies of the useful band within a sufficiently low-impedance connection in the frequency range of the meter waves.
  • this can be done by capacitors (58), e.g. can be achieved by soldered chip capacitors, corresponding capacitance value.
  • Electrically equivalent behavior of an antenna according to the invention without influencing the heating currents through the structure of the antenna conductors (12) in the second area can also be achieved by replacing the galvanic connection between the first area and the second area by a connection, which has no direct current passage, but causes a sufficiently low-resistance connection for the frequencies of the useful band within the frequency range of the meter waves. According to FIG. 12, this can be achieved in the same way as in FIG. 11 by capacitors (58) corresponding to the capacitance value applied to the pane.
  • the common connection point (8) on the merging antenna conductor (10) is always in the area (42) of the pane, i.e. in a region symmetrical about the line of symmetry (3) and that with a width corresponding to half the mean pane width ( 5).
  • an overall symmetrical structure is recommended, with the result that the connection point (8) is generally also arranged on the line of symmetry (3).
  • connection point (8) and the decoupling point (23 ) in the vicinity of the frame it may still be necessary to place between the connection point (8) and the decoupling point (23 ) in the vicinity of the frame to establish a connection through the continuing antenna conductor (22), with the continuing antenna conductor (22) then also expediently likewise being arranged along the line of symmetry.
  • the continuing antenna conductor (22) expediently likewise being arranged along the line of symmetry.
  • connection point (8) will generally also not be arranged on the line of symmetry (3) of the pane, but will be offset parallel to the line of symmetry of the pane, so that, from an optical point of view, the further antenna conductor (22) can advantageously also be routed parallel to the two lateral frame edges or the line of symmetry.

  • a typical arrangement according to the invention is shown by way of example in FIG. 1, in which the further network (16) is attached in the region of the left side of the frame and the further antenna conductor (22) starting from the connection point (8) initially along the line of symmetry of the pane up to close of the frame is guided, bends at the break point (57) and is further guided parallel to the upper frame edge to the right up to the vicinity of the upper right corner to the decoupling point (23). If necessary, further inflection points (57) may also be required if the continuing network (16) is in a suitable position.
  • the size of the distance (60) from FIG. 1, in which the further antenna conductor (22) is routed parallel to the respective frame edge, is to be selected depending on the objective that is sought for an antenna according to the invention.
  • this distance (60) must be small, i.e. in the range of approx. 1 cm to 5 cm.
  • this dimensioning With this dimensioning, with the same values of the exciting field strength on the one hand for a horizontally polarized and on the other hand for a vertically polarized wave field, there is a considerable increase in level during the transition from horizontal polarization to vertical or circular polarization in a similar order of magnitude as that of rod antennas mounted vertically on the vehicle is known here.
  • the distance (60) of the further antenna conductor (22) to the frame can be freely selected.
  • Antenna diversity systems require several antennas with different behavior with regard to reception interference. It is known that it makes sense to implement several antennas in a single vehicle window for such systems.
  • Two such diversity antennas can be advantageous as Antennas according to the invention are executed when the heating field is divided in the vehicle window in question.
  • Fig. 5 shows such an arrangement, the two continuing networks (16) being attached at almost diagonally opposite points in the vicinity of the frame. Since the areas of the two antennas that are essential for reception are each arranged in the area of the vertical line of symmetry of the disk, these two antennas do not have a very distinctly different behavior in wave fields which are only slightly disturbed by multipath propagation because of their similarity of the geometries.
