Definitions

  • the exemplary and non-limiting embodiments of the invention relate generally to connecting arrangements that can be employed to interconnect radiofrequency apparatuses or components.
  • Connectors are used in radiofrequency apparatuses to connect apparatuses or components within an apparatus electrically to each other.
  • a typical arrangement in connecting an antenna radiator to the reflector plate or main body of the antenna is to use screws for the mechanical fixing and solder a radio frequency (RF) cable to the reflector
  • Figures 1A and 1B illustrate an example of an arrangement where embodiments of the invention may be applied.
  • the figures show an antenna system 100 comprising a main body 104 and a second body 102.
  • the main body comprises the reflector of the antenna and the second body comprises the radiator of the antenna.
  • the antenna is a dipole antenna and the radiator 102 is a diploe radiator.
  • Figure 1A is a cross-sectional view of the antenna while Figure 1B is an exploded assembly of the antenna.
  • the arrangement comprises one or more first connectors 106A, 106B, 106C, 106D mounted on the main body 104 of an antenna.
  • Each first connector comprises a first outer connector 108 and a first inner connector 110.
  • the example of Figures 1A and 1B illustrate a co-axial structure where the outer connector surrounds the inner connector. In an embodiment, there is an even number of first connectors 106A, 106B, 106C, 106D.
  • the arrangement further comprises one or more second connectors 112A, 112B, 112C in the radiator 102 of the antenna.
  • Each second connector comprises a second outer connector 114 and a second inner connector 116.
  • the second inner connector 116 is connected to the radiator with a non-conductive connection.
  • the first connector 106A, 106B, 106C, 106D mounted on the main body 104 of the antenna is attachable to the second connector 112A, 112B, 112C, 112D in the radiator 102 of the antenna.
  • the first connector is attachable to the second connector essentially perpendicularly in relation to the main body of an antenna.
  • first outer connector 108 is attachable to the second outer connector 114 in such a manner that the attachment provides a galvanic connection between the first outer connector 108 and the second outer connector 114 and mechanically locks the first connector and the second connector together.
  • the first outer connector may comprise attaching means mechanically locking first connector and the second connector together.
  • the second outer connector may comprise attaching means mechanically locking first connector and the second connector together.
  • the first inner connector 110 is attachable to the second inner connector 116 in such a manner that the attachment provides a capacitive connection between the first inner connector 110 and the second inner connector 116.
  • the second inner connector 116 is realised with a capacitive cross coupler. Radio frequency is fed through the first inner conductor 110 to the second inner connector 116 or the capacitive cross coupler.
  • the arrangement may comprise a stub capacitor 118 for grounding.
  • air coaxial line is utilised.
  • the air coaxial line has a mechanical locking mechanism for antenna radiator (for example in dipole and patch antennas).
  • This air coax bushing can be installed to different kinds of reflector types or antenna base materials such as aluminium sheet metal, aluminium extrusion, aluminium/magnesium casting or printed card board PCB.
  • the proposed mechanical structure allows automatic assembly in production from one side of reflector. Main RF lines are realised with non-galvanic contacts which provide good electrical performance.
  • the proposed solution is well suited also for active antenna array solutions.
  • the proposed solution provides a good mechanical implementation of press fit air coax bushings to metallic part.
  • the antenna structure is as firm as possible.
  • the solution may be utilised in a wide variety of applications.
  • the same generic parts for connectors may be utilised in many applications. This enables big volumes in manufacturing which leads to lower unit cost.
  • Antenna radiators do not need other fixing parts such as screws.
  • the structure is poka-joke suitable so all human assembly mistakes can be avoided.

  • the arrangement further comprises two second connectors 112A and 112B mounted on the reflector 204 of the antenna.
  • Each second connector comprises a second outer connector and a second inner connector.
  • the second outer connectors connect the first outer connectors to the reflector. The attachment of the first outer connectors to the second outer connectors provide a galvanic connection between the first outer connector and the second outer connector and mechanically lock the first connector and the second connector together.
  • the second inner connectors connect the first outer connectors to the radiator 202 of the antenna.
  • the attachment provides a capacitive connection between the first inner connector and the second inner connector.
  • an antenna comprises a main body and at least one second body. If there is one second body, it may be a radiator. In such a case the reflector typically lies with the main body of the antenna. If there are more than one second body, there may be a separate reflector and a separate radiator.
  • Figure 2B illustrates another example of an arrangement where embodiments of the invention may be applied.
  • a cable 210 is used between the second body and the main body of the antenna.
  • the second connector is connected to the first connector, and the other end of the cable is connected to the radiator.
