Definitions

  • This invention relates to beam forming antenna systems.
  • the invention provides an antenna system comprising an antenna array having a plurality of arrayed antenna elements and a plurality of signal processing units respectively associated to said antenna elements and adapted for at least amplifying signals being fed from and/or to said respectively associated antenna elements, wherein said plurality of antenna elements and said associated signal processing units are commonly arranged on a flat supporting substrate which has flexibility and electric insulating property.
  • the object of the present invention is creating a simple and easy-to-handle antenna system being suitable for two-dimensional antenna arrays and allowing a flexible structure for various applications and deployment scenarios.
  • the antenna system according to the invention is an array antenna having a flexible flat supporting substrate that carries the antenna elements and the processing units.
  • the antenna system of the present invention can be realized by printing the antenna elements and the processing units on a flexible plastic foil forming that supporting substrate.
  • the present antenna system preferably forms a two-dimensional array, wherein the antenna elements are distributed vertically and horizontally on the flat and supporting substrate. In cases where the two-dimensional antenna array is bent or gets a three-dimensional shape depending on its application, the present antenna system has a third dimension in space.
  • Each antenna element preferably can be controlled individually thus allowing e.g. beam forming or spatial multiplexing exploiting elevation and azimuth direction.
  • the present antenna system can be realized by applying the antenna elements and even the signal processing units, e.g. by printing, on a flexible plastic foil which may be inflatable to become a balloon-like antenna object thus having a three-dimensional shape.
  • the balloon-like antenna object may thus become a flying antenna object if inflated by a light gas.
  • the inflated status of the inflatable flexible (elastically deformable) plastic foil may determine the respective frequency range of the antenna elements and/or the processing units of the balloon-like antenna object.
  • Signal processing for the present antenna system can be carried out at least partly by the processing units respectively associated to the antenna elements and provided and arranged on the flat flexible supporting substrate.
  • Signal processing of the present antenna system can also be carried out by means of a separate base station which may be provided at the exterior of the antenna array.
  • the signal processing adapts to the actual size and/or shape of the antenna array resulting from the application and adapts to the antenna deployment and/or operation.
  • the amount of the plurality of arrayed antenna elements and the plurality of signal processing units gives redundancy. Thus, if a single antenna element or processing unit is not functional, there are enough antenna elements and processing units in total remaining to be used from the signal processing entity. This concept allows various forms and sizes of the antenna array which also allows large antenna apertures. Flexible and thin antenna arrays according to the present invention can be easily and quickly deployed by just sticking them on objects where they are needed:
  • the present antenna system may be applied to an air borne vehicle such as Zeppelin-like object or a balloon or also to a marine vehicle or to a marine-based beacon.
  • the present antenna system may be applied to a stationary object, such as a building, an industrial facility, a power plant, a tower, a mast, a chimney, or a beacon.
  • the present antenna system may be applied to a portable object, such as a cloth, a hat, a helmet, a portable telephone, a portable or movable radio transceiver and the like.
  • at least the antenna elements and the signal processing units are applied by printing on said supporting substrate.
  • the deployed antenna array on the flexible plastic foil can have any sort of bends and shapes depending on the object it is attached to or depending on the inflated status of the balloon-like antenna object. Therefore, as mentioned above, a signal processing adapts to the actual array shape and/or size of the array resulting at deployment and/or usage. Further, as mentioned above, a frequency range of said inflatable antenna object can be determined by the size or inflated status thereof.
  • the antenna array including the antenna elements and the processing units can be linked to a base station partly carrying out the processing functions of the present antenna system.
  • the link can be carried out by various technologies such as:
  • the present antenna system can be arranged in combination with thin batteries, solar cells, fuel cells, etc., wherein thin batteries may also be applied and arranged on the flexible flat supporting substrate.
  • the present antenna system having the above advantageous features thus allows complete new deployment scenarios in mobile wireless communication systems, adding more flexibility, allowing improved public acceptance by avoiding classical antenna shapes and by creating signal processing concepts. Further the present antenna system provides a low cost and very flexible new technology option.
  • the first embodiment of the invention as depicted in Fig.1 and described in the following description relates to an antenna system A comprising an antenna array having a plurality of arrayed antenna elements and a plurality of signal processing units respectively associated to said antenna elements and adapted for at least amplifying signals being fed from/or to said respectively associated antenna elements, wherein said plurality of antenna elements and said associated signal processing units are commonly arranged on a flat supporting substrate which has flexibility and electric insulating property.
  • How to apply the present antenna system according to this invention to a variety of exemplary applications is schematically depicted in Figs. 2 to 7 and will be described in the following description.
  • the antenna system A comprises an antenna array 11, 12, Vietnamese, 1l, 21, 22, ....,3n, 41, 42, ....4o having a plurality of two-dimensionally arrayed antenna elements only a part of which are designated by reference numbers 111, 211, 311, 411 and further a plurality of two-dimensionally arrayed signal processing units simply and schematically depicted as transistor symbols and only partly designated by reference numbers 112, 212, 312, 412.
  • Signal processing units 112, 212, 312, 412 are respectively associated to a respective antenna element 111, 211, 311, 411 and adapted for at least amplifying signals being fed from/or to the associated antenna elements 111, 211, 311, 411.
  • Signal transmission means 6, e.g. signal transmission lines are likewise arranged on the flexible substrate 10 for transmitting signals to/from the antenna elements 111, 211, 311, 411 and/or to/from the processing units 112, 212, 312, 412.
  • the flat flexible supporting substrate 10 can have any sort of bends and shapes depending on an object to which it is attached or depending on a specific application of the present antenna system A.
  • the processing units have an amplifying function, however, may additionally have certain other processing functions for the signals being fed from and/or to the respectively associated antenna elements.
  • FIG. 1 shows that the processing units 112, 212, 312, 412 are also locally associated to the respective antenna element 111, 211, 311, 411, but alternatively the processing units 112, 212, 312, 412 may locally be concentrated at different sites on the flat flexible supporting substrate 10 even if these processing units are operatively one-to-one associated to the respective antenna elements 111, 211, 311, 411.
  • the signal processing adapts to the actual array shape and /or size of the antenna array.
  • Fig. 1 further depicts that in addition to the plurality of signal processing units 112, 212, 312, 412 the present antenna system may comprise a base station 8 provided in the exterior of the antenna array, i.e. the base station 8 is not arranged on the flexible flat supporting substrate 10 but linked to the plurality of signal processing units and/or the antenna elements on the flat flexible supporting substrate 10 by means of a signal communication link 7.
  • This signal communication link 7 can be realized in various technologies, such as micro-wave link, free space optics (diffused or directed), in-band techniques (relaying, etc.), cable (copper or optical fiber).
  • the latter may be combined with any possible power generation means such as thin batteries, solar cells, fuel cells, etc.
  • Fig. 1 indicates that a solar cell battery 9 or alternatively a thin battery 9 can be arranged and fixed directly on the flat flexible supporting substrate 10.
  • the plurality of antenna elements 111, 211, 311, 411 and associated signal processing units 112, 212, 312, 412 can be arranged with redundancy on the flexible supporting substrate 10. If a single antenna element and/or processing unit is not functional, the amount of redundant antenna elements and/or signal processing units can be used to maintain the functionality of the antenna system A.
  • the present concept of the inventive antenna system A allows to individually control the plurality of antenna elements 111, 211, 311, 411 by the associated signal processing units 112, 212, 312, 412 and/or by the base station 8.
  • the individual control of each antenna element allows to adapt the antenna system to at least one of the actual shape of the antenna array, the actual size thereof and to the number of antenna elements actually being in operation.
  • each single antenna element by the associated processing unit allows beam forming or spatial multiplexing exploiting elevation and azimuth direction.
  • the signal processing functionality beyond the amplifying function can be located partly or fully directly on the flexible flat supporting substrate 10 or it can be fully or partly implemented at the base station 8. Accordingly, the signal processing functionality can be located at both the flexible flat supporting substrate 10 and in the base station 8. I.e. the whole processing function (besides the amplifying functions carried out by the processing units 112, 212, 312, 412 of the antenna array) may be totally or partly implemented in the base station 8. Signal processing functions can be provided for signals fed from the signal processing units to the base station 8 and/or signals to be supplied from the base station 8 to the signal processing units 112, 212, 312, 412.
  • the functionality of altering the antenna characteristic of the antenna system A in response to a corresponding control signal being for example supplied from the exterior to the antenna system A can be either partly or totally carried out by the base station 8 instead of being carried out by the signal processing units 112, 212, 312, 412 on the flexible flat supporting substrate 10.
  • the flexible supporting substrate 10 depicted in Fig. 1 comprises a plastic foil.
  • This allows to apply at least the antenna elements 111, 211, 311, 411, signal processing units 112, 212, 312, 412 and signal transmission lines 6 by a printing process on the flexible plastic foil 10 used as the flat flexible supporting substrate.
  • the base station 8 can be totally or partly be printed on the flexible plastic foil 10 instead of being installed at the exterior of the flexible plastic foil 10 like it is described for the antenna system of the first embodiment as shown in Fig. 1 .
  • a flexible protecting layer (not shown) can be applied on the flexible plastic foil 10 and adapted for covering and protecting at least the antenna elements 111, 211, 311, 411, the signal processing units 112, 212, 312, 412 and the signal transmission lines 6 on said flexible plastic foil 10 against harmful environmental interference.
  • the first embodiment of the antenna system A of the present invention described above with reference to Fig. 1 forms a basis for complete new deployment scenarios in mobile wireless communication systems, adds more flexibility, allows improved public acceptance by avoiding classical antenna shapes and creates new signal processing concepts. Further the embodiment of the present antenna system A described above achieves a low cost flexible technology option.
  • FIG. 2 An exemplary second embodiment depicted in Fig. 2 shows the antenna system A according to the present invention applied to an air borne flying object F, in the example a propelled Zeppelin.
  • the flexible flat supporting substrate 10 carying the antenna elements, the signal processing units and the signal transmission lines as depicted in Fig. 1 is used to create an inflatable flying antenna object such as a balloon (unpropelled) where optionally the flexible supporting substrate 10 itself may be inflatabe.
  • signal processing is either located at the antenna array applied to the flying object, at a base station linked by a communication link to the antenna array or at both, the base station and the antenna array.
  • a size of the balloon, in particular an inflated status of the inflatable flexible plastic foil may determine the respective frequency range of the antenna elements and/or the processing units of the balloon-like antenna object.
  • the flying antenna system A of the invention can be used for e.g. quickly setting up wireless communication, broadcast or surveillance networks at events with many users such as sport events.
  • the flying antenna system A can be linked to a base station via various technology options mentioned above.
  • combination with thin batteries, solar cells, fuel cells, etc. are preferred.
  • the flying object carrying the antenna system A of the present invention is propelled by an engine such as the propelled Zeppelin according to Fig.2 , some power from the engine can also be used for the power supply of the electronics of the signal processing, or the engine even is a full power supply for a full base station carried onboard a flying object carrying the present antenna system A.
  • a third exemplary embodiment is schematically depicted in Fig. 3 where the antenna system A of the present invention is applied to a ground vehicle V exemplified as a motor-driven bus.
  • the antenna system A of the invention can be applied inside a bus, inside trains, etc. and further on different vehicles like private cars, police cars, firefighter cars, military vehicles, etc.
  • the antenna system A according to the present invention can be applied at a marine vehicle, such as a ship or ferry.
  • FIG. 4 A fourth exemplary embodiment is depicted in Fig. 4 where the antenna system A according to the present invention is applied to a marine beacon B.
  • Figs. 5 and 6 respectively show a fifth and sixth embodiment where the antenna system A is applied to a tower T and to a chimney K, respectively.
