Definitions

  • the present invention is in the field of radio frequency (RF) systems and in particular provides a conductor coupling apparatus for enabling capacitive coupling between conductors of a RF system.
  • RF radio frequency
  • Common RF systems e.g. antenna systems
  • various RF system components which in particular can be based on printed circuit boards (PCBs).
  • PCBs printed circuit boards
  • conductors of the RF system components are often coupled by using soldered connections, which leads to longer manufacturing time and higher manufacturing costs.
  • soldered connections stress or heat can be caused at the soldered connections and the soldered connections can be damaged.
  • An alternative solution for coupling RF system components without soldering is mechanically fixing together RF system components by fastening elements, for example by screws or rivets.
  • PIM passive intermodulation
  • JP 2002 164706 A discloses a phase converter.
  • embodiments of the present invention provide a coupling of conductors, suitable for use with PCBs and allows for an easy to implement, reliable, non-galvanic and solder-less coupling between the conductors, particularly in respect to thermal influences.
  • the invention provides a conductor coupling apparatus, comprising: a conductive coupling member configured to cover a portion of a first conductor and a portion of a second conductor, wherein the conductive coupling member is further configured to be separated from the first conductor and/or the second conductor by dielectric material and wherein the conductive coupling member is configured to provide a capacitive coupling between the first conductor and the second conductor, at least one first support member, configured to press the conductive coupling member towards the first conductor and/or the second conductor whereby the conductive coupling member is secured slidably against the first conductor and the second conductor, and at least one second support member configured to support the first conductor and/or the second conductor, wherein the at least one second support member is or comprises at least one resilient means, and is configured to press the conductive coupling member towards the first conductor and/or the second conductor.
  • the at least one second support member provides mechanical stability to protect the first conductor and/or the second conductor and/or the conductive coupling member from being damaged, when mechanical forces are applied.
  • the at least one second support member is or comprises at least one resilient means
  • the conductive coupling member can additionally be pressed towards the first conductor and/or the second conductor by the at least one second support member, which improves mechanical stability and quality of capacitive coupling, as air gaps between the conductors and/or the dielectric material and/or the conductive coupling member can be further reduced.
  • the resilient means further enables to stronger secure the conductive coupling member against the conductors by still allowing for movement of such.
  • the at least one first support member can be or can comprise at least one resilient means.
  • the resilient means ensures quality of capacitive coupling, as it avoids air gaps between the conductive coupling member, the dielectric material and the conductors, which can negatively affect coupling quality.
  • the resilient means specifically enables to secure the conductive coupling member against the conductors by still allowing for movement of such.
  • the at least one first support member and the at least one second support member can preferably be configured to slidably secure together, and more preferably clamp together, the conductive coupling member and the first conductor and/or the second conductor, and/or the at least one resilient means can be configured to be electrically isolated from the conductive coupling member.
  • the slidable security in particular allows for a relative movement of the conductive coupling member against the first conductor and/or the second conductor, e.g. by sliding the conductive coupling member along the first conductor and/or the second conductor. Consequently, movement resulting from an expansion or contraction of the conductive coupling member, the first conductor and/or the second conductor, e.g. due to a thermal influence, can be compensated and does no longer lead to damage of the coupling or to connection loss.
  • the slidable security also ensures that complex manufacturing techniques such as soldering or screwing can be avoided. Specifically, mechanical fastening means, e.g. screws, can be omitted. Electrically isolating the at least one resilient means from the conductive coupling member allows to ensure low-PIM operation
  • the conductive coupling member can be configured to be arranged adjacent to the at least one first support member and/or the at least one second support member and in particular can be configured to be affixed to and/or to be embedded in the at least one first support member and/or the at least one second support member.

  • This provides a way of mechanically supporting the at least one resilient means or the at least one first support member and/or the at least one second support member by the first ground plane and/or the second ground plane, which leads to increased overall mechanical stability of the conductor coupling apparatus. Additionally, the overall conductor coupling apparatus profits from being shielded by the first ground plane and/or the second ground plane. As ground planes can already be part of common RF systems, an advantageous way of integrating the conductor coupling apparatus into common RF systems is provided.
  • no mechanical fastening means can be provided, and/or the conductive coupling member and the first conductor and/or the second conductor can be slidably secured together only by a clamping force, in particular applied by the at least one first support member and/or the at least one second support member.
