Definitions

  • the invention relates to a window pane antenna arrangement according to the preamble of claim 1.
  • Such antennas are widely used on the window pane of a motor vehicle, which is surrounded by a metallic frame.
  • antenna conductors of this type are known from DEP 3315458, DEP 3410415 and DEP 4406240. With all antennas of this type, the antenna conductors are designed as wire-shaped conductors which are either printed on the single-pane safety glass or are introduced as wire structures between the glass panes of a laminated safety pane.
  • a disadvantage of such antenna window panes is the heat radiation that enters the interior of the vehicle and heats it up.
  • transmission-reducing coatings have been developed in the past, which can be constructed in one or more layers.
  • Such a coating is often very low-resistance in electrical terms, particularly in the case of high transmission damping, and the surface resistance is often only a few ohms.
  • Antenna conductors which are applied to a glass pane coated in this way are severely impaired in their function by shielding and detuning by the galvanic connection or in the case of capacitive high-frequency coupling to this conductive layer.
  • the antenna conductors are usually implemented as often complex conductor structures printed in wire form or formed by wires.
  • European laid-open specification 0 358 090 therefore proposes to make this conductive coating sufficiently high-resistance so that the function of the antennas on the window pane is not impaired too much. For this reason, a surface resistance of 20 kOhm is required. Layers of such high impedance, however, have a comparatively low transmission loss for heat radiation.
  • Fig. 1 A wire-shaped, flat antenna for LMK reception on the window of a vehicle with narrow horizontal strips 6 separated low-ohmic coated partial areas 12 for high-frequency decoupling of the antenna from the window frame 2 and a low-resistance layer 5 in the lower region of the Light transmission area of the window opening 14.
  • Fig. 2 LMK antenna, as in Fig. 1, in the rear window of a car with high-frequency grounded heating conductors 9th
  • Fig. 3 A flat antenna with printed conductors 3 for LMK reception and with flat heating antennas for FM reception with
  • REPLACEMENT LEAF 6 separate, electrically low-resistance coated with narrow and vertical strips
  • Sub-areas 12 for high-frequency decoupling of the antennas from one another are Sub-areas 12 for high-frequency decoupling of the antennas from one another.
  • Fig. 4 LMKU antenna as a wire-shaped antenna conductor 3 on or above an electrically low-resistance conductive partial surfaces 12 separated by narrow two-dimensional strips 6 for high-frequency decoupling of the individual wire sections from one another.
  • FIG. 1 shows an antenna arrangement according to the invention, which consists of a wire structure 3, as is known from DEP 3410415, and has good reception properties in the low-frequency LMK range in conjunction with the window opening 14 of conventional automobiles.
  • the low-resistance coating required due to the reduction in heat transmission is divided into partial areas 12 which are separated from one another by means of narrow, non-conductive strips 6 are arranged separately in such a way that practically the entire surface of the window opening 14 is covered with the electrically conductive layer 5 and the highest possible degree of surface coverage is achieved with regard to the heat radiation transmission.
  • the originally continuously electrically conductive layer 5 thus becomes the structured electrically conductive layer 10, as is shown in FIG. 1 above and below the LMK antenna conductor 3 by the hatched at 45 degrees Areas is marked.
  • a section of the structured electrically conductive layer 10 is shown enlarged.
  • the electrically conductive partial surfaces 12 then fill the area between the strips 6 in strips and have the transverse dimension d.
  • the area that remains uncovered is insignificant with regard to thermal insulation.
  • the electrically conductive layer 5 in some areas in the form of the structured electrically conductive layer 10, it is important to avoid dimensions of the sub-areas 12 which cause the formation of electrical resonances at the operating frequencies of the antenna 3 or the antennas 3 avoid.
  • the structured electrically conductive layer 10 formed in this way is thus high-frequency transparent for the operating frequencies of the antenna, but only allows the heat radiation to be adequately attenuated.
  • Resonances on the sub-areas 12 can certainly be avoided by none of their dimensions being greater than lambda / 10.
  • the smallest operating wavelength of which is approximately 50 m all dimensions are small compared to Lambda / 10.
  • the partial areas 12 in the immediate vicinity of the antenna conductors 3 must have sufficiently small dimensions in the vertical direction, so that between each point on one of the wire-shaped antenna conductors 3 and the metallic frame 2 as well as the coherent, electrically low-impedance conductive located in the lower region of the light transmission region of the window opening 14 Layer 5 (dotted area) a plurality, but at least three non-conductive strips 6 are preferably formed approximately equidistantly from one another, as a result of which the structured electrically conductive partial area 10 is formed, with the aim that the capacitive coupling between the antenna conductors 3 and the metallic frame 2 as well the coherently low-resistance layer 5 is sufficiently small.
  • the heat protection layer ends in the area of black printing 8, so that the antenna function is not impaired by contact with the possibly high-frequency-damping adhesive bead 7 which connects the window pane to the vehicle.
  • LMK antenna as in Fig. 1 and in Fig. 2 acts as a flat antenna, so that the low-resistance layer 5 between the two outer conductors 3 can be designed either as a continuous or as sub-areas 12 with non-conductive strips 6 in between. It is therefore essential to separate the electrically conductive layer 5, that is to say the heat protection layer, in the vicinity of the planar antenna by means of non-conductive strips 6 in the manner described, as a result of which the structured electrically conductive layer 10 again results. This largely removes the coupling between the antenna conductors 3 of the LMK antenna and the frame 2 and also the heating conductors 9, which in this example form other conductor parts 13 on the vehicle window.
  • FIG. 3 shows a further development of the invention for higher frequencies at which the vehicle dimensions are not small compared to the wavelength.
  • a window pane antenna arrangement according to the invention with an antenna arranged above for LMK reception and below that two antennas for FM reception, which are derived from the heating fields, is considered. All of the antennas shown can optionally be flat.
  • the simply hatched areas again characterize the electrically low-resistance coated partial areas 12 separated by narrow horizontal and vertical strips 6 in this example for high-frequency decoupling of the antennas from one another.
  • a two-dimensionally structured electrically conductive layer 10 in the form of a lattice structure made of narrow electrically non-conductive strips 6 is therefore used for the antenna arrangement according to the invention.
  • the two-dimensional lattice structure allows the permeability of these areas for radio waves and the high-frequency decoupling of the antennas from one another as a result of the sufficient high impedance of the resulting surface impedance, which results even at very small widths b of the strips 6.
  • the antenna behavior is to be determined largely exclusively by the wire-shaped antenna conductors 3 and the thermal insulation is to have little influence on the antenna behavior, then it is expedient in a further embodiment of the invention to also use the dotted areas in FIG 3 to be provided with the two-dimensionally structured electrically conductive layer, that is to say, for example, low-resistance coated partial surfaces 12 separated by narrow horizontal and vertical strips 6 to be used in the area of the heating conductor 9.
  • This procedure is to be continued analogously to the edges of the window frame 2, provided that the thermal insulation cannot be completely omitted due to the likewise thermally insulating black printing 8 applied there.
  • the influence of the width b of a non-conductive strip 6 between two partial surfaces 12 of the layer thicknesses s on the capacitance between the partial surfaces 12 as a function of b / s does not vary by more than a factor of 2.5 if a ratio b / s of 2 is not undershot .
  • a disadvantage of the known, coherently conductive layers in the vicinity of antennas is the fact that these layers carry large coupled currents, in particular with a small surface active resistance R, which entail losses and the layers have a shielding effect.
  • REPLACEMENT LEAF Antenna arrangement can be covered by such a raster structure without shielding or evaporating the antennas behind.
  • the small widths b of the non-conductive strips that are permitted for the function of the antennas allow both the practically complete shielding of the short-wave heat radiation compared to the dimensions of the partial areas 12 and the aesthetic impairment of the window pane by wide strips 6 to be avoided.
  • Such structured layers can be produced in a manner known per se by applying the initially homogeneous layer, e.g. with the aid of a conventional cathode sputtering process, and the introduction of the non-conductive strips 6 can be carried out with the aid of a light-sensitive lacquer and the customary photoetching technique, or with laser processes or ion beam etching.
  • Fig. 4 shows a wire-shaped antenna 3, as it is advantageous for the LMKU area, e.g. in vehicle windscreens.
  • Such an antenna is known from DEP 3315458.
  • it is necessary to increase the inductance or capacitance per unit length of the wire by considerably less than an order of magnitude change.
  • the shielding effect which would have a uniformly coherent layer, is eliminated, so that when the non-conductive strips 6 are formed, only an electrical detuning effect of the antenna is brought about, which with a sufficiently large number of strips 6 by
  • FIG. 5 shows an example of an embodiment of such an antenna system on the rear window pane of a vehicle, as is known from DEP 4406240.
  • the terminals 18 represent the end points of the antenna conductors 3 as connection points for the FM and TV antennas.
  • 17 identifies the mounting area of a radio antenna 15 which is mounted in the middle of the window at the top.
  • 6 shows some examples of the arrangement of the electrically conductive layer 5 damping the heat transmission and its specific embodiment according to the invention as a structured electrically conductive layer 10 and the antenna conductors 3.
  • 6a shows the joint application on one side of a single-pane glass. In this case, the conductive subareas are in galvanic contact with the antenna conductors.
  • REPLACEMENT LEAF A particular advantage of the present invention results from the fact that the structured heat-insulating layer 10 formed in this way does not have to assume a specific position in relation to the antenna conductors. This applies in particular in the case of sufficiently small dimensions d of the conductive subareas 12. This results in the possibility of particularly simple manufacture in the series production of antenna window panes.
  • the plastic film 4 intended for the laminated glass production is applied on the left with a grid structure according to FIGS. 4 and 5, and if the antenna conductors 3 are printed on the window glass as in FIGS. 6b and c, the plastic film 4 can be used in the production of the laminated glass between the panes without considering the position of the grid with respect to the antenna conductor 3.
  • the specimen scatter of the antenna properties which result from the different positions of the grid relative to the antenna conductors 3 in series production, can be tolerated due to the fineness of the grid.
  • the coherently conductive surface 11 necessary for other reasons in FIG. 5 can also be printed as a printed conductive surface on the window glass on the side of the antenna conductor, where it can act, for example, as an electrical counterweight and as a grounded shielding surface against radio fields penetrating into the vehicle interior.
  • junction 18 through the heat-insulating layer structured in this way is also possible with the arrangement shown in FIG. 8.
  • two mutually opposite conductive surfaces 17 are applied to the outer sides of the laminated glass pane, to which the antenna on one side and e.g. a high-frequency line 16 is connected.

Abstract

La présente invention concerne une antenne montée sur vitre avec un ou plusieurs conducteurs (3) ou structures (3) conductrices montés sur ou dans la vitre (1) de la fenêtre pour une multiplicité d'anntennes utilisées pour divers services radioélectriques. Dans la zone de transmission de lumière de l'ouverture de fenêtre s'étend, sur la vitre, une couche (5) électroconductrice d'une certaine épaisseur et ayant la propriété d'atténuer la transmission du rayonnement thermique. Cette couche est répartie en un nombre suffisant de fractions de surface (12) électroconductrices. Ces fractions de surface (12) sont séparées par d'étroites bandes non électroconductrices (6) de largeur (b), cette largeur équivalant à trois épaisseurs de couche au minimum. Les dimensions des fractions de surface (12) électroconductrices sont électriquement si faibles dans leur plage de fréquences de fonctionnement, du moins à proximité de l'antenne, que, en reliant en série tous les petits condensateurs ainsi formés entre les zones électroconductrices (12), le couplage indésirable haute fréquence, dû à l'incorporation de zones électroconductrices (12), entre les parties (3) conductrices de l'antenne (3) et les autres parties conductrices à proximité de l'antenne, est maintenu à un niveau suffisamment modeste, et la largeur (b) des bandes reste suffisamment étroite pour assurer une maximisation de la zone recouverte par la couche à effet d'atténuation de la transmission thermique.
