Definitions

  • the present invention relates generally to the field of radio communications and particularly to antenna devices for use in portable radio communication apparatus, and to such portable radio communication apparatus.
  • the conventional method of electrically connecting such an electronic component being of a miniature size is to interpose between the electronic component and the printed circuit board, an electrical connector such as a so-called pogo pin connector.
  • the pogo pin is an elongated pin containing a head, which makes contact with one surface and can be compressed by its connection to a spring within a socket of the pin that is soldered to the printed circuit board.
  • An object of the present invention is to provide an antenna device for use in a portable radio communication device, which comprises a spring-loaded connector that provides for a well defined contact towards a contacted object, such as e.g. a printed circuit board, and is adapted for transfer of RF energy.
  • a further object of the present invention is to provide such an antenna device, which is easy and inexpensive to manufacture and assemble.
  • Still a further object of the present invention is to provide a portable radio communication apparatus, such as e.g. a mobile telephone, comprising an antenna device, which is simple, inexpensive and includes a well-defined connector suitable for transfer of RF energy.
  • Advantages of the present invention include inter alia manufacture and assembly of an antenna device including antenna element connectors to a lower cost; the use of less components in the device; and less contact points within the device which provides for a better and more well defined electrical connection for transfer of RF energy.
  • Fig. 1 illustrates, schematically, in a perspective view, an antenna device according to the present invention.
  • Fig. 2 illustrates, schematically, in an enlarged perspective view, part of the antenna device of Fig. 1 with portions removed to illustrate spring-loaded connectors as being comprised in the antenna device.
  • Fig. 3 illustrates, schematically, in an enlarged cross section view, part of the antenna device of Fig. 1.
  • the antenna device generally designated 1
  • the antenna device comprises a dielectric substrate, antenna carrier, or support structure 3 having a substantially planar main surface 5 on which an electrically conductive antenna pattern 7 is arranged, and is intended to be used in a portable radio communication apparatus such as a mobile telephone (not illustrated) .
  • Socket 9 houses an electrically conductive spring 11, e.g. gold plated, which is electrically connected to antenna pattern 7, and an electrically conductive pin connector 13, which can be slidably moved in socket 9 in a direction parallel with axis 15, while compression spring 11 exerts a force thereon. In such manner a spring-loaded antenna connector for transfer of RF energy is achieved.
  • an electrically conductive spring 11 e.g. gold plated
  • an electrically conductive pin connector 13 which can be slidably moved in socket 9 in a direction parallel with axis 15, while compression spring 11 exerts a force thereon.
  • substrate 3 including socket 9 By manufacturing substrate 3, including socket 9, in a single piece of dielectric material, fewer components are needed to be assembled during production.
  • socket 9 is arranged with respect to main surface 5 of dielectric substrate 3 such that pin connector 13 can be moved in a direction substantially perpendicular to main surface 5 of substrate 3.
  • antenna pattern 7 is extended to cover the interior walls 19 of socket 9; such antenna pattern extension is indicated by reference numeral 17, and the conductive compression spring is arranged in physical contact with the extended conductive antenna pattern in socket 9. Such contact may be ensured by having a very close fit between spring 11 and the inner walls 19 of socket 9.
  • the metallized inner walls 19 may be formed separately of antenna pattern 7 and connected thereto capacitively .
  • the metallized inner walls 19 may be formed separately of antenna pattern 7 and connected galvanically thereto by means of other conductor such as a conductive strip, wire, or the like.
  • socket 9 is provided with rounded edges 21, and conductive antenna pattern 7, including the extension into socket 9 and the interior walls thereof, which is formed thereon, is formed with rounded edges 23.
  • the antenna pattern 7, including the extension through the through hole 26 to cover the interior walls of the socket 9, may be formed in a relatively simple metallization process, such as in an MID process.
  • socket 9 includes an inner edge 27 towards which compression spring 11 is pressed when being compressed by the pin connector 13. Further, a cap 29 is arranged at the outer end of socket 9. Cap 29 is preferably releasably attachable to socket 9, e.g. by means of a snap-in arrangement, and is further provided with a through hole through which pin connector 13 is guided. Pin connector 13 is provided with a wider portion or head 31 in an end thereof and is oriented such that wider portion 31 is facing spring 11 and is located within socket 9.
  • pin connector 13 is projecting from socket 9, but is hindered from being ejected from socket 9 by means of cap 29 (wider portion 31 is large enough not to pass through the hole of cap 29) .
  • the antenna device thus described is preferably mounted in a portable radio communication apparatus such that the pin connector 13 of the antenna device is pressed against a connection point of e.g. an RF feed circuit of a PCB of the portable radio communication device (not illustrated) .
  • the antenna device may alternatively be connected to other electrical component or part of the portable radio communication apparatus.
  • the present antenna/connector assembly may be used to connect to a further antenna element or antenna device.
  • the antenna device may include a second and a further spring-loaded connector arrangement.
  • a second such spring-loaded connector arrangement including inter alia a second socket 9a, a second electrically conductive compression spring 11a and a second electrically conductive pin connector 13a.
  • Such second pin connector may be connected to a grounding point of the portable radio communication device or to any RF feed circuit e.g. to enable multi-band functionality.
  • conductive antenna pattern has been used for indicating the radiant element of the device. It is to be understood that this term covers virtually any antenna, such as e.g. a conventional or modified PIFA, micro-strip, patch, or meander antenna, adapted to receive or transmit electromagnetic waves.
  • an antenna device has been described.
  • the person skilled in the art realizes that such embodiment can be varied within the scope of the appended claims.
  • the shapes of the different parts shown in the figures can be adapted to different needs, uses and applications.
