Definitions

  • the invention relates to an antenna arrangement for frequencies above the high-frequency range, which is mounted in a window pane, in particular a motor vehicle window, together with a heating field for the window heating.
  • Antennas are known from DE 36 184 52 A1 and from published patent application DE 37 196 92 A1, in which the heating field or the heating fields on a pane are also used as antennas for the reception of signals in the meter wave range.
  • the antenna connections are each located on the busbars and on a point of the metallic frame which is adjacent to the connection point on the busbar and which generally surrounds the entire window pane in the form of the conductive body.
  • the possibility is used to tap different reception signals at different points on the busbars and the frame for further processing in an antenna diversity system.
  • the antenna conductors and the heating conductors are designed as conductors printed on the glass and in the case of multi-pane laminated glass as thin wires inserted between the glass panes.
  • the number of antennas that can be formed by tapping received signals on the busbars is limited due to the difficulty of the required decoupling between these signals.
  • the number of subdivisions is very limited for a number of vehicle-technical reasons and, not least, also for cost reasons for the number of decoupling networks required as a result.
  • FR-A-2282728 describes a vehicle window which has both an antenna and a heating field with vertical heating conductors for heating the vehicle window.
  • the antenna is arranged in a central area of the vehicle window that is free of a heat conductor, while the heating field is divided into two partial heating areas, each on the side of the central area, are separated from the antenna by a conductor-free space.
  • FR-A-2 2601194 also describes a motor vehicle window pane antenna which is at the same time arranged in the window pane with a heating field consisting of parallel conductors.
  • the antenna consists of a flat conductor, which is inserted as a transparent, electrically conductive film between the layers of a laminated glass.
  • the heating conductors are electrically insulated from it on the outside of the laminated glass.
  • the object of the invention is therefore to show surprising possibilities in an antenna arrangement of the generic type, such as in a motor vehicle window with a heating field other antennas can be accommodated for which the above restrictions do not exist.
  • Fig. 2 Antenna arrangement according to the invention with two conductors lying substantially perpendicular to the heating conductors and connected to these with high-frequency, low-resistance to enlarge the capacitively acting area.
  • connection point 9 on the heating conductor 5 at a not too large distance 11 from the capacitively effective surface for connecting the antenna connection point 8.
  • FIG. 5b Antenna arrangement according to the invention as in FIG. 5a, but with only one vertical conductor, with additional conductors parallel to the heating conductors.
  • Fig. 5c antenna arrangement according to the invention as in Fig. 5a, but with connection of a second antenna part in the asymmetrical point of the surface.
  • Fig. 6 Antenna arrangement according to the invention, in which the capacitive surface for increasing the capacity is formed by stylistic ornaments made of conductive material.
  • Antenna arrangement according to the invention but consisting of two capacitively acting surfaces in a heating field or partial heating field and the antenna connections 8a and 8b for decoupling antenna signals between the terminals 8a and 8b or the terminal pairs 8a and 3 and 8b and 3.
  • Antenna arrangement according to the invention but consisting of two capacitive surfaces, both of which are formed in separate partial heating fields with the antenna connection point 8a and 8b for decoupling the antenna signals from the pane field with a line perpendicular to the window pane.
  • Fig. 8c Antenna arrangement according to the invention as in Fig. 8a, with the antenna connection point 8a and 8b for decoupling the antenna signals from the pane field with a line perpendicular to the window pane, hidden, e.g. under a spoiler.
  • the window pane being built into the plastic frame of a body, but with a conductive frame with an interruption point, for example, attached along the edge of the pane, the interruption point to form a resonance effect is connected to a suitable complex impedance Z.
  • 10b First and second antenna parts printed on the glass pane 1a for an antenna according to FIG. 10a, wherein to increase the high-frequency coupling between the conductor part 6 and the heating wires opposite the plastic film, parallel conductors 24 are printed.
  • 10c Cross section through a laminated glass pane according to FIG. 10a with the glass pane 1b and the heating conductors 5 lying there, the insulating film 26a and the capacitive conductors 24 printed on the opposite glass pane 1a.
  • Fig. 12 Like Fig. 11, but only with three antennas.
  • Fig. 13 Meandering design of the heating wires in some areas to improve the decoupling between adjacent capacitively acting surfaces and the busbars.
  • Fig. 14 Diversity antennas in a window pane with two divided heating fields and three antennas according to the invention, an additional antenna in the free space above the heating field and possibly with prior art antenna connections on the busbars at the edge of the pane.
  • FIG. 1 shows a heatable window pane 1 with heating conductors 5 which are parallel to one another and run horizontally in this example.
  • the busbars for supplying the direct heating current with the busbar connections 15 and 16 are arranged essentially perpendicular to the heating conductors. In the case of vertically arranged heating conductors, the busbars are essentially horizontal. All of the effects described below can be transferred analogously to the case of vertical heating conductors.
  • the heating conductors are either screen-printed on the surface of the vehicle window and then galvanically reinforced to achieve a low-resistance value required for heating purposes, or in vehicles made of double-pane laminated glass, between the two glass windows, e.g. in the form of thin tungsten wires.
  • the heating conductors 5 are wire-shaped.
  • the area of a vehicle window covered by the heating field is usually so large 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 the published patent application DE 3719692 A1 .
  • FIG. 1 shows the basic arrangement of an antenna according to the invention. This consists of the heating conductors 5, a first conductor part 6 of the wire-shaped antenna conductors and a second conductor part 7. This arrangement aims to produce a coupling to the heating conductors 5 for the design of a capacitively acting surface for the antenna.
  • This area is indicated by dashed lines in FIG. 1 and is formed from the first conductor part 6 of the wire-shaped antenna conductors, which crosses the parallel heating conductors almost vertically and is connected to them at the intersection points 25 with high-frequency, low-impedance, so that the crossed heating conductors are connected to each other in the area of the capacitively acting surface at a relatively low-impedance, high-frequency.
  • the heating conductors shown horizontally in the figure and crossed by the conductor 6 contribute in the vicinity of the crossing points 25 to the formation of the capacitively acting surface 10. Due to the wire-shaped design of the heating conductors, they have a relatively large inductive resistance per unit length in their longitudinal direction.
  • the first conductor part 6 of the wire-shaped antenna conductors is designed in such a way that it connects the heating conductors crossed by it to one another in a comparatively low-resistance manner.
  • the second conductor part 7 of the antenna conductor is used, with its antenna connection point 8 at the edge of the pane, where the antenna signal is tapped between the connection points 8 and the ground point 3 of the conductive frame 2 surrounding the pane. It is important, among other things, that there is a high-frequency, low-impedance connection at the intersection points 25 between the horizontal heat conductors 5 in the example and the first conductor part 6 of the wire-shaped antenna conductors.
  • the first conductor part 6 of the antenna conductor for the heating currents would represent undesirable shunts, via which compensation currents can flow between the individual heating conductors 5 which are parallel to one another, as a result of which the defrosting properties of the heating disk are undesirably changed.
  • this is avoided in that the first part 6 of the antenna conductor crosses the heating conductors 5 in such a way that the individual crossing points 25 lie on a line of the heating voltage which Points equal Potentials connects so that hardly any compensating currents flow in the antenna conductor 6.
  • FIG. 2 A particularly advantageous embodiment of a capacitively acting surface 10 is shown in FIG. 2, in which two first antenna conductors 6a and 6b are laid parallel to one another along equipotential lines of the heating voltage, that is to say essentially perpendicular to the heating conductors 5 running parallel to one another.
  • the coupling to this capacitive surface takes place by connecting the second antenna part 7 to the connection point 9, which is located on a heating conductor 5.
  • the connection point 9 is chosen approximately in the middle between the conductors 6a and 6b.
  • An advantageous embodiment of the invention relates to the second antenna part, which is formed in FIG. 3 as conductors 7a, b and c and 7.
  • This arrangement leads to a reduction in the effective inductance of this antenna part, which results in an increase in its capacitive effect, so that the total capacitance of the antenna at the connection point 8 essentially consists of the capacitively acting surface 10 and the capacitively acting surface which is formed by the conductors 7a, b and c.
  • connection point 9 of the second antenna part 7 it may be necessary, as in FIG. 4, to attach the connection point 9 of the second antenna part 7 to a heating conductor 5 at a distance 11 from the next first antenna part 6a. Adequate coupling To ensure the capacitively acting surface 10 on the second antenna part 7, the distance 11 must be chosen to be sufficiently small.
  • FIGS. 5a, 5b and 5c in order to enlarge the capacitively acting surface 10 in the spaces between the heating conductors, additional conductors parallel to these are introduced, which are connected to the conductor parts 6 and 6a, 6b.
  • the capacitively acting surface 10 can also, as in FIG. 6, be effectively enlarged by high-frequency conductive stylistic ornaments 13, which preferably connect adjacent heating conductors 5 to one another via the intersection points 25 with high-frequency, low-impedance.
  • the Decoupling can be increased by introducing inductive elements into the heating conductor. In FIG. 7, this is brought about by inductances 14, which are realized by a meandering design of the heating conductors.
  • the inductance of the heating conductor 5 can, for. B. can also be enlarged by applying a ferrite material. If the heating conductor is meandering, e.g. a ferrite plate can be glued to the meander structure.
  • All antennas according to the invention thus have the advantage that the electrical system for direct current supply to the heating field can generally be connected to the busbars without separate networks which influence the high-frequency impedance between the busbar and the body. In the event that small, impedance-correcting networks should nevertheless be necessary, these can be made considerably less complex if the distance 26 is chosen accordingly.
  • the heating conductors 5 arranged parallel to one another are arranged essentially horizontally in the vehicle window.
  • the reception of vertically polarized waves is essential, in particular for antennas for the radio telephone, but also in some countries for antennas for FM radio reception.
  • the vertically polarized electric fields are usually received particularly well.
  • Antennas whose antenna connection point is formed on the busbars, do not have this advantage and therefore preferably receive electromagnetic waves with horizontal polarization.
  • two capacitively acting surfaces are formed within the heating field.
  • the second antenna conductors 7a and 7b are led to the connection points 8a and 8b.
  • the connection points 8a and 8b together with a conductive frame 2 and a ground point 3 located in the vicinity of the antenna connection points 8a and 8b, three antenna voltages arise in the case of reception.
  • two capacitive surfaces 10a and 10b are also used, the first antenna parts 6a and 6b of surface 10a or 6'a and 6'b of surface 10b being different in order to increase the decoupling of these surfaces from one another Partial heating fields are arranged, which are fed in direct current via busbar pairs 4a, 4b and 4c, 4d separated from one another at high frequency. Due to the horizontal distance 27 of the two surfaces 10a and 10b and the two heating fields arranged one above the other, a dipole-like antenna is formed between the antenna connections 8a and 8b, which has both a vertical and a horizontal extension and thus for the reception of vertically polarized waves as well is also suitable for horizontally polarized waves.
  • the antenna conductors 7a, 7b of the second antenna part 7 are guided to the points 28a and 28b on the pane surface and the conductors 7a 'and 7b' in attached substantially perpendicular to the motor vehicle window and led to the connection points 8a and 8b, which are located, for example, in the area of a plastic spoiler 21.
  • the antenna conductors 7a and 7b in FIG. 8c can also be designed as heating conductors 5, if these are of the capacitive type Surfaces 10a and 10b would be extended towards the busbars.
  • a choke with sufficient inductance could then be used, for example, to bridge the direct current path between the terminals 8a and 8b.
  • a conductive frame 22 around the pane edge e.g. printed on.
  • this conductive frame 22 can be interrupted at a suitable point and brought to resonance in a desired frequency range by wiring with a frequency-dependent complex impedance 20.
  • FIG. 10a shows an antenna in a double-pane laminated glass.
  • this is formed by the fact that the heating conductors 5 are embedded as thin wires on one side of the insulating film 26a in FIG. 10c and antenna conductors 6 are introduced on the other side of the thin insulating film 26a, such that between the conductors 6 and the heating conductors 5 have the largest possible capacitive coupling.
  • the conductors 6 are provided with horizontal conductors 24 in FIG. 10b, which run parallel to the heating conductors over their length.
  • the antenna conductor configuration consisting of the second antenna part 7, the first antenna part 6 with the horizontal capacitive conductors 24, is preferably printed on the glass pane 1a, as can be seen in FIG. 10b.
  • the busbars are interrupted and by introducing first antenna conductors 6a, 6b, 6c and 6d to the corresponding second antenna conductors 7a, 7b, 7c and 7d are connected, four connection points 8a, 8b, 8c, 8d are formed for four antennas decoupled from one another, the respectively associated ground connection 3 being formed on the adjacent metallic frame 2.
  • the heating currents are supplied via the busbar terminals 15a and 16a or 15b and 16b.
  • This arrangement also enables the formation of four further antenna connections on the busbars, provided that these are connected via their connections to the direct current network for supplying heating current with the aid of appropriate decoupling networks.
  • These antenna connection points are formed in FIG. 11 with the connections 15a, 15b and 16a and 16b, it being possible for the respective ground connection to be found at the adjacent frame point.
  • the busbars can be operated without antenna connections when the invention is used, and the capacitively acting surfaces thus formed can be sufficiently decoupled in terms of radio frequency by suitable attachment of the first antenna conductors 6a, 6b and 6c in FIG. 12.
  • the decoupling takes place by choosing a suitable distance 27. In practice, this distance is given by half the distance between the busbars.
  • the third capacitive Surface that is formed with the first antenna conductor 6a is decoupled from the busbars and thus from the other two capacitively acting surfaces around the first antenna conductors 6b and 6c in that the first antenna conductor 6a does not cross any heating conductors that are also from the antenna conductors 6b and 6c are crossed. This and by attaching it in the middle of the pane ensures the greatest possible length of a heating conductor path between the conductor 6a and the conductors 6c and 6b.
  • the decoupling between the capacitively acting surfaces is not sufficient, the decoupling can be increased by introducing separating inductive elements which, as shown in FIG. 13, are realized by meandering the heating conductors between the individual capacitively acting surfaces 10.
  • the busbars of the upper and lower heating fields are connected to one another via high-frequency insulating chokes 17.
  • the reception of LMK is also necessary.
  • Their receive voltage can be tapped between points 8d and 3. This tap can also be used for the reception of the FM frequencies, so that the antenna in FIG. 14 has a total of four FM antennas for antenna diversity and one LMK antenna.
  • the possibility of realizing a large number of individual antennas with the aid of the heating field by designing the capacitively acting surfaces according to the invention can also be used to form certain desired directional diagrams in the transmission case as well as in the reception case.
  • a desired directional diagram can be achieved better than with a smaller number of available antennas.
