Definitions

  • the present disclosure relates to a multilayer printed circuit board, PCB, having an antenna element, and to a manufacturing method of a multilayer PCB antenna element.
  • PCBs Printed circuit boards having multiple layers and including one or more antenna elements for transmitting and receiving an RF signal are known in the art.
  • a PCB having RF functions for example a PCB of a mobile device such as a mobile phone, smartphone etc., typically has severe space constrictions due to a high demand for miniaturization. That is, a typical PCB with RF functions is already crowded.
  • the PCB components such as surface mounted device components (SMD) and the like are typically arranged on a planar surface, i.e. on the topmost layer or in between the layers. Providing an antenna element at such a location reduces the space available for the other PCB components.
  • SMD surface mounted device components
  • Document WO 2017/194096 A1 describes an antenna formed on a multilayer PCB edge, the antenna comprising an antenna patch and a feeding patch.
  • the antenna patch is formed of multiple conductive strips each arranged on a different layer of the multilayer PCB, which requires a high amount of work for obtaining this conventional structure and is prone to undesired variations of the radiation properties due to the multi-element configuration.
  • document WO 2017/194096 A1 also describes a dipole structure formed on an edge of the multilayer PCB.
  • a dipole needs to be fed through a matching network such as a balun, which requires additional space.
  • Document EP 3 051 628 A1 describes a multilayer circuit board having a plurality of vertical interconnect access (VIA) holes formed in the multiple layers and arranged in a horizontal direction.
  • the VIA holes line up with a plurality of VIA holes in another layer, whereby a grid-type radiation member is formed.
  • the VIA hole antenna elements that form the resulting grid-type radiation member are disposed as a grid-array that, as a whole, act as an RF patch. That is, a plurality of VIA hole antenna elements act together in transmitting or receiving an electromagnetic wave by means of the grid-array. Due to the fact that this conventional technique uses a plurality of VIA holes, a large amount of space is required.
  • a multilayer printed circuit board according to claim 1 is provided.
  • the PCB comprises a plurality of layers.
  • the plurality of layers are stacked in a stacking direction and extending in a planar direction up to an edge of the PCB.

  • the antenna element is formed as a resonant structure.
  • the antenna element is formed as a single resonant structure.
  • the antenna element is formed as a multi-element resonant structure.
  • feeding is made by a galvanic connection between the RF feeding structure and the antenna element.
  • feeding is made by capacitive coupling between the RF feeding structure and the antenna element.
  • a manufacturing method of an antenna element of or for a multilayer printed circuit board (PCB) according to claim 10 comprises providing a PCB having a plurality of layers, the plurality of layers being stacked in a stacking direction and extending in a planar direction up to an edge of the PCB, wherein the layers comprise an RF feeding structure extending up to the edge and a short-circuit conductor extending up to the edge.

  • a single resonant structure is considered a structure that is different from e.g. an antenna array.
  • an antenna array comprises a plurality of emitting elements whose emitted electromagnetic waves interact with each other, e.g. in a way that a constructive or destructive interference occurs.
  • a single resonant structure is considered to emit an electromagnetic wave substantially without any electromagnetic interaction such as constructive interference or destructive interference with neighboring like structures.
  • a single resonant structure is, as to its RF usage or configuration, a non-periodical structure or a non-array structure.
  • a single-resonant structure may prove advantageous in that it occupies a comparatively small amount of space, even in the edge area of the PCB.
