Definitions

  • the invention relates to a leaky wave antenna and a method for producing a leaky wave antenna.
  • a leaky wave antenna is an antenna that delivers power in small quantities per unit of length either continuously or discretely from a leaky wave line or leaky wave structure to the free space.
  • leaky wave antennas in the form of coaxial lines are often used, which have a plurality of corresponding openings along the line in the outer jacket, each of which has the same shape due to the manufacture and which are used as slot antennas.
  • coaxial leaky wave antennas usually have the disadvantage that the respective output of electromagnetic power of the individual antennas along the line is not the same due to the manufacturing process, but rather decreases over the length.
  • a leaky wave antenna in which at least one line, each with a feed point, is embedded in an insulating layer, and the insulating layer is arranged between an electrically conductive lower layer and an electrically conductive upper layer, wherein a plurality of antenna elements in the form of openings along the at least one line are introduced in the upper layer, and a coupling means is provided between the at least one line and a respective antenna element from the plurality of antenna elements, which defines a respective coupling factor that describes the electromagnetic coupling between the at least one line and the respective antenna element, and, starting from the respective entry point, the coupling factor of the respective antenna element increases along the at least one line.
  • the invention consequently builds on an embedded strip line.
  • the conductor strip is covered by an equally thick dielectric at the top and bottom and runs parallel to two conductive layers (ground) which are applied to the dielectrics.
  • ground conductive layers
  • the distance to both ground surfaces can also be different (offset stripline).
  • layers and layers are parts of a composite material which is to form the leaky wave antenna in the finished state.
  • the term layer or layer should not be interpreted restrictively with regard to the type of material or the manufacturing process.
  • the layers and layers can for example be made of a flexible material such as plastic, foam with air pockets, metal foils or a woven fiber material. Depending on the application, materials based on glass fiber or Teflon can also be used.
  • a flexible material such as foam is preferably used for the layers, as is a material with a low relative permittivity, such as less than two or three, or a combination of a flexible material and with a low relative permittivity.
  • the layers and layers can, for example, be piece by piece from a solid material, such as FR4 or Teflon circuit board carriers with one-sided, two-sided or multilayer metallization for line layers, individual plates being fed piece by piece to the method according to the invention and then being connected in succession and to one another.
  • a solid material such as FR4 or Teflon circuit board carriers with one-sided, two-sided or multilayer metallization for line layers, individual plates being fed piece by piece to the method according to the invention and then being connected in succession and to one another.
  • the layers and layers can be made of a material, for example, which is printed on, sprayed on, or sprayed on by foils or plates, or is applied by a chemical or physical process. Openings or structures, for example for coupling means, can also be provided in the layers and / or layers.
  • the plurality of antenna elements of the leaky wave antenna comprise at least ten, preferably at least thirty and particularly preferably at least fifty antenna elements, since the effect according to the invention can be perceived particularly advantageously with increasing line length compared to the prior art.
  • the necessary transmission power can be reduced accordingly, since Even the last located antenna element of the leaky wave antenna, starting from the entry point, can be adequately supplied with power. Furthermore, the reception of electromagnetic power from the last located antenna element of the leaky wave antenna can also be improved.
  • the leaky wave antenna according to the invention allows a uniform delivery and a uniform reception of electromagnetic power over the entire length of the leaky wave antenna. This makes the leaky wave antenna especially suitable for use when mounting on elongated objects with many antenna elements, in particular train wagons, fuselages or buildings.
  • the length of the at least one line of the leaky wave antenna is at least five meters, preferably at least ten meters and particularly preferably at least 20 meters and is therefore greater than a single typical use in the production of printed circuit boards.
  • a benefit usually includes several printed circuit boards during their manufacture and can be limited to the dimensions of the production systems used.
  • a maximum benefit size or PCB size can vary depending on the PCB manufacturer and technical equipment. Based on the standard panel cut 610 mm * 530 mm, which is often processed, many manufacturers have maximum dimensions of approx. 570 mm * 490 mm.
  • the base materials for printed circuit boards can undesirably shrink or stretch during a printed circuit board manufacturing process (dimensional stability), which increases the size can limit a circuit board. Furthermore, in the case of very large printed circuit boards or in the case of large benefits, the positioning of structures or components on the printed circuit boards cannot always be carried out with the required accuracy, or an undesirable offset from layer to layer of the printed circuit board can arise with increasing size. Bending a large panel during transport in transport devices can lead to unfavorable mechanical stresses, for example in the case of solder joints.
  • At least two lines are included, which are preferably provided for feeding in or coupling out electrical signals with different frequencies in each case.
  • the insulating layer has a first insulating layer and a second insulating layer, which are preferably each formed by a foam material. This results in a particularly inexpensive design, which is also mechanically flexible and therefore simplifies assembly.

  • an electrical and / or mechanical connection can be created, by means of which the leaky wave antenna can be attached to other components, or a signal coupling or signal coupling for example with a corresponding high-frequency connector.
  • a leaky wave antenna according to the invention is provided as part of a communication device in an aircraft, a train or a building.
  • This provides a method for the simple and inexpensive production of a leaky wave antenna, which allows a uniform delivery and a uniform reception of electromagnetic power over the entire length of the leaky wave antenna, which is particularly suitable for long line lengths of the leaky wave antenna.
