Definitions

  • the present invention relates to antenna systems.
  • insulated glass consists of two or more glass panes, also referred to as double-glazed window or triple-glazed window. Between the glass panes, which are arranged in a defined distance to each other, a gas, e.g. argon is present. On at least one glass pane, a thin metallization is applied for further reducing thermal losses. The thickness of the metallization is that low that the metallization stays nearly invisible.
  • a gas e.g. argon
  • the present invention concerns an antenna, e.g. for wireless communication systems like LTE, UMTS, WiFi, WiMAX, etc.
  • the antenna structure is e.g. a patch or dipole antenna, wherein at least one conductive layer is applied on a substrate or other carrier medium. Such antennas may or may not have a reflector for focusing an electromagnetic beam radiated by the antenna.
  • At least one part of the conductive antenna structure, e.g. the metallic dipole or patch is metalized onto at least one glass pane of a window.
  • the window itself serves as carrier medium.
  • Metalized within this context is to be understood as a metallic deposit, e.g. film, coat, sputtering or layer, which is applied to at least a part of the window pane.
  • Such metal deposit is applied to the window pane e.g. by sputtering, laminating or plotting the metal onto the carrier medium or by other known methods of application of the metal onto the carrier medium.
  • the metallization is attached irremovably.
  • the metallization is usually of a thickness that it does not affect the transparency of the window too much.
  • the metallization is of the nature and of the thickness that the window is mirrored from one side and only transparent in one direction.
  • the metallization is of the nature and of the thickness that the clarity of the window is reduced, thus providing a sun blocking window. All these kinds of metallization and other known methods of metallization are suitable to realize the antenna structure.
  • the antennas may be integrated in buildings in windows, without being visible to the audience.
  • the structure of the antennas would only be visible if the window is inspected in greater detail, but not by casually looking at the window.
  • the audience will not be negatively affected by the integrated antenna in the window.
  • the antenna structure is realized closely to the window frame or at another part of the window, where the audience usually looks at with less attention. As window panes in modern heat absorbing windows are metalized anyway, costs for the antenna are kept low.
  • the antenna structure is integrated into an at least double-glazed window.
  • the antenna patch structure is metalized on one glass pane and a reflector is metalized on another glass pane.
  • the antenna structure is integrated into a single glass pane.
  • the antenna patch structure is metalized on the one side of the glass pane.
  • the reflector is metalized on the other side of the glass pane.
  • the glass pane is used as dielectric material between patch and reflector.
  • the single glass pane may be part of a double-glazed window, or may be the inner glass of a triple-glazed window. In the latter case, the metallization layer is inside the window and cannot be destroyed or scratched from the outside.
  • the antenna structure is protected against environmental conditions.
  • the metallization is on the inner surfaces of the glass panes of the at least double-glazed window.
  • the metallization providing the patch and the reflector is within the double-glazed window and cannot be destroyed or scratched from the outside.
  • the antenna structure is protected against environmental conditions.
  • multiple patches forming a patch antenna array are metalized on one glass pane.
  • At least part of the antenna structure is realized in the metallization of heat absorbing glass panes.
  • the metallization layer is reused in order to reduce costs.
  • the antenna structure is realized in proximity to the window frame. This has the advantage that the feeding line between antenna patch and RF electronics is short and electric losses are minimized. Further, even if the antenna structure is realized in a metallization layer which is invisible, the antenna structure may disturb somebody inspecting the window in greater detail. If the antenna structure is located closely to the window frame, it will not attract attention.
  • At least part of the RF electronics is mounted in the window frame. Mounting e.g. the power amplifier and the low noise amplifier in the window frame keeps the distance between these RF components and the antenna patch short. This has the advantage that losses in the feeding line are kept minimal.
  • a wireless base station transceiver comprises at least one antenna realized in a window as described above.
  • Fig. 1 shows a window antenna integrated in a double-glazed window.
  • the window consists of two window panes 10, 11 of the thickness t and a window frame 13.
  • the two window panes 10, 11 are arranged to each other with a certain distance d, leading to a well defined space 12 between the two window panes 10, 11.
  • the space 12 may be filled with air or with a gas which increases isolation properties of the window. Further, in one embodiment, the gas filling in the space 12 between the window panes 10, 11 increases directivity of the antenna.
  • a metallization is attached.
  • the metallization provides heat isolation and is of a thickness so that it is almost invisible.
  • An antenna structure is integrated in the metallization.
  • the antenna structure is a microstrip antenna with a directly connected feeding line as described in greater detail in Fig. 3 and the corresponding description.
  • the antenna structure 14 is realized in one metallization layer on one side of a window glass 10.
  • the antenna structure 14 including feeding line is realized in one metallization layer on one side of a window glass 10.
  • a reflector 15 is realized in a metallization layer to improve the directivity of the antenna.
  • the antenna is realized having a coupled feeding line
  • the antenna structure consists for example of an antenna patch 14 on the inner side of a first window pane 10 and a feeding line 15 on the inner side of the second window pane 11.
  • the feeding line 15 and the antenna patch 14 are inductive coupled.
  • the feeding line 15 is realized in a coplanar manner providing additionally a ground plane on the inner side of the second window glass 11 in order to improve directivity of the antenna.
  • at least a power amplifier 16 for the transmitting path and/or a low noise amplifier 16 for the receiving path is integrated in the window frame 13 in order to keep the feeding line between antenna structure and RF electronics short.
  • even more RF circuits 16 and baseband logic 16 are integrated in the window frame 13.
  • one of antenna patch 14 and feeding line 15 is integrated in the heat absorbing metallization attached to the window pane 10, 11.
  • the other element 14, 15 is attached on the other window pane 10, 11 in a metallization layer not explicitly designated to heat absorbing purposes.
  • only the feeding line structure is realized in this metallization layer covering only a small part of the whole window surface.
  • Fig. 2 shows a window antenna integrated in a triple-glazed window.
  • the window consists of three window panes 20, 21, 26 of the thickness t and a window frame 23.
  • the window panes 20, 21, 26 are arranged to each other with a certain distance d, leading to well defined spaces 22 between the window panes 20, 21, 26.
  • the spaces 22 may be filled with air or with a gas which increases isolation properties of the window.
  • At least at one side of at least one window pane 20, 21, 26 a metallization is attached.
  • the metallization provides heat isolation and is of a thickness so that it is almost invisible.

  • one of an antenna patch 24 and a feeding line 25 is integrated in the heat absorbing metallization attached to one side of a window pane 20, 21, 26.
  • the other element 24, 25 is attached either to the other side of the window pane 20, 21, 26 or to another window pane 20, 21, 26 in a metallization layer not explicitly designated to heat absorbing purposes.
