Definitions

  • the invention relates to an antenna for frequencies above the high-frequency range with one or more wire-shaped antenna conductors 6, 6a, b, c connected at one end at high frequency and an antenna connection point 8, which antenna in a window pane, e.g. a motor vehicle window 1, with window heating is arranged together with a heating field, which is formed by essentially parallel wire-shaped heating conductors 5, which are connected at the ends adjacent to the window edges in each case by a busbar 4a, b running transversely to the heating conductors for supplying the heating direct current are.
  • antennas of this type are known e.g. from DE 3618452.A1 and from the published patent application DE 3719692 A1.
  • the antenna connections are in each case 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 the multi-pane laminated glass as thin wires inserted between the glass panes.
  • the number of antennas that can be formed by tapping received signals at the busbars is limited due to the difficulty of the required decoupling between these signals.
  • To form several antennas from the heating field it is therefore necessary according to the prior art - when the antenna signals are tapped from the busbars - to decouple the antennas from one another, to divide the heating field simply or repeatedly by interrupting the busbars.
  • the number of subdivisions is very limited for a number of vehicle-technical reasons and not least also for reasons of cost for the number of decoupling networks required as a result. Therefore, there is a desire share the heating field as an antenna, but keep the number of antenna connections on the busbars as small as possible.
  • 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 heating direct 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.
  • the aim of the invention is 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 conductor, which crosses the parallel heating conductors almost vertically and is connected to them at the crossover points 25 with a low frequency, so that the crossed heating conductors are capacitive acting area relatively low impedance are connected to each other at high frequency.
  • the heating conductors shown horizontally in the figure and crossed by the conductor 6 also contribute to the formation of the capacitively acting surface 10 in the vicinity of the crossing points 25. 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 busbars 4a and 4b in FIG. 1 are well decoupled in terms of radio frequency.
  • the capacitively acting surface 10 as an element of the antenna can act largely independently of the high-frequency wiring of the busbars 4a and 4b if the distance 26 of the first conductor part 6 from these busbars is chosen to be sufficiently large. The distance must therefore be chosen to be large depending on the decoupling requirement and the realization of the crossed heating conductors and their number. It is therefore essential that the first conductor part 6 of the wire-shaped antenna conductors is designed in such a way that it connects the heating conductors which it crosses with one another and has a relatively low resistance to one another.
  • the second conductor part 7 of the antenna conductor with its antenna connection point 8 on 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, is used for coupling to the capacitively acting surface 10 formed in this way. It is essential for an antenna according to the invention that, among other things, there is a high-frequency, low-resistance connection at the intersection points 25 between the horizontal heating conductors 5 in the example and the first conductor part 6 of the wire-shaped antenna conductors.
  • a capacitively acting surface 10 can be produced, as will be explained in more detail later with reference to FIGS. 10a to 10c.
  • the first conductor part 6 of the antenna conductor for the heating currents represents undesirable shunts, via which compensating 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 Connects points of the same potential so that hardly any compensating currents flow in the antenna conductor 6.
  • An antenna according to the invention can e.g. also similar to FIG. 1, but with vertical heating conductors, the first conductor part 6 of the antenna conductor being guided along an equipotential line, which in this case then represents an essentially horizontal line.
  • FIG. 2 A particularly advantageous embodiment of a capacitively acting surface 10 is shown in FIG. 2, in which two first conductor parts 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 conductor 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 further development of the invention relates to the configuration of the second conductor parts of the antenna conductors, which are formed in FIG. 3 as conductors 7a, b and c and 7.
  • This arrangement leads to a reduction in the effective inductance of these conductor parts, which results in an increase in their capacitive effect, so that the total capacitance of the antenna at the connection point 8 essentially results from the capacitive surface 10 and the capacitive surface that extends through the conductors 7a, b and c.
  • connection point 9 of the second conductor part 7 it may be necessary, as in FIG. 4, to attach the connection point 9 of the second conductor part 7 to a heating conductor 5 at a distance 11 from the next first conductor part 6a.
  • the distance 11 In order to ensure a sufficient coupling of the capacitively acting surface 10 to the second conductor part 7, the distance 11 must be chosen to be sufficiently small.
  • FIGS. 5a, 5b and 5c additional conductors parallel to these are introduced in FIGS. 5a, 5b and 5c in order to enlarge the capacitively acting surface 10 in the spaces between the heating conductors, said conductors being 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 crossover 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 effected by inductors 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 conductors are 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 vehicle 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 much 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.
  • the vertically polarized electric fields the intensity of which is usually received particularly well with increasing distance 26 of the vertical unipole from the vertical disk edge.
  • Antennas whose antenna connection point is formed on the busbars do not have this advantage and therefore preferably receive horizontal electromagnetic waves Polarization.
  • two capacitively acting surfaces are formed within the heating field.
  • the second conductor parts 7a and 7b of the antenna conductors are led to the connection points 8a and 8b.
  • 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 conductor parts 6a and 6b of surface 10a or 6a and 6b of surface 10b being arranged in different partial heating fields to increase the decoupling of these surfaces. which are fed in direct current via mutually high-frequency separated busbar pairs 4a, 4b and 4c, 4d. 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 second conductor parts 7a, 7b of the antenna conductor 7 are guided to the points 28a and 28b on the disk surface and the conductor parts 7a 'and 7b' in attached substantially perpendicular to the motor vehicle window and led to the connection points 8a and 8b, which are, for example are in the area of a plastic spoiler 21.
  • the second conductor parts 7a and 7b of the antenna conductors in FIG. 8c can also be designed as heating conductors 5 if they were extended from the capacitive surfaces 10a and 10b to the busbars.
  • To bridge the direct current path between terminals 8a and 8b e.g. serve a choke with sufficient inductance.
  • a conductive frame 22 printed around the edge of the pane, for example.
  • 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 26 in FIG. 10c and first antenna conductors 6 are introduced on the other side of the thin insulating film 26 such that The largest possible capacitive coupling is created between the conductors 6 and the heating conductors 5.
  • 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 conductor part 7, the first conductor part 6 with the horizontal capacitive conductor parts 24, is preferably printed on the glass pane 1a, as can be seen from FIG. 10b.
  • the largest possible number of antennas with different reception properties is necessary.
  • the entire pane surface is to be heated and thus the heating structure covers the entire surface, multiple use of the heating pane as an antenna is desirable.
  • the busbars are interrupted and by introducing first antenna conductors 6a, 6b, 6c and 6d to the corresponding second conductor parts 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 15 a and 16a or 15b and 16b.
  • This arrangement also enables the formation of four further antenna connections on the busbars, provided that they 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 Figure 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 capacitive-acting surfaces formed in this way can be sufficiently decoupled in terms of radio frequency by suitable attachment of the first conductor parts 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 decoupling from the busbars and thus from the other two capacitive surfaces takes place around the first conductor parts 6b and 6c in that the first conductor part 6a does not cross any heating conductors , which are also crossed by the conductor parts 6b and 6c.
  • the greatest possible length of a heating conductor path between the conductor 6a and the conductors 6c and 6b is guaranteed.
  • 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 one smaller number of available antennas.
  • antennas according to the invention are listed in brief: - Small number of decoupling networks for direct current supply - When using decoupling networks, the circuit complexity can be kept low. - The placement of the capacitively acting surfaces in the central area of the antenna disc allows the strong electromagnetic fields located there to be decoupled when received. Accordingly, a particularly good coupling of the antenna to the radiation field is possible in the case of transmission. (Reciprocity). - Due to the preferably horizontal laying of the heating conductors and the almost vertical arrangement of the second conductor parts, antennas with a unipole character and vertical alignment can be designed, which are also very suitable for the reception of vertically polarized waves.
