Definitions

  • the present invention relates generally to antennas, and particularly to a connector for an antenna device in a portable radio communication device, such as a mobile phone or similar.
  • One crucial space limitation is the height of the antenna device that it occupies in the portable radio communication device.
  • An object of the present invention is to provide a connector for an antenna device in a portable radio communication device that builds minimal height of the connector and thus also of the antenna device and consequently the portable radio communication device.
  • a connector comprising an upper portion and a lower portion foldable against each other, wherein the upper portion is provided with engagement means for securing the upper portion to a dielectric carrier of an antenna device that it is mounted on, and wherein the lower portion is arranged to be positioned between the upper portion and the dielectric carrier and is provided with resilient means arranged to conductively connect to a radiating element of the antenna device a connector building minimal height is provided.
  • the antenna device By having the radiating element of the flexible film of the antenna device arranged towards the dielectric carrier, i.e. facing the dielectric carrier, the antenna device attain an external surface, i.e. the flexible film, having considerably better finish than with the radiating element facing out from the dielectric carrier. Further, with the radiating element between the flexible film and the dielectric carrier it is also possible to omit the step of applying a solder resist mask to the radiating element, which is applied to all surfaces apart from contact surfaces, which entails cost savings for manufacturing of the antenna device. The radiating element yet further attains a better protection against corrosion and mechanical wear, compared to when the radiating element is facing out from the radiating element.
  • the engagement means is arranged to be positioned in an aperture in the dielectric carrier by snap fitting in order to clamp a contact portion of the radiating element between the upper and lower portions, whereby easy mounting of the connector is provided maintaining minimal height building of the connector.
  • the upper portion is preferably provided with a resilient means arranged to conductively connect to a printed wiring board of a portable radio communication device into which said antenna device is mounted, whereby reliable connection to the printed wiring board is provided.
  • the resilient means allows increased manufacturing tolerances.
  • the connector is positioned in a recess in the dielectric carrier, whereby minimal height building of the antenna device is achieved.
  • an antenna device for a portable radio communication device comprising a flexible film, a radiating element, a dielectric carrier and a connector as described above is manufactured as an assembly, providing a cost effective antenna device, which further provides for a cost effective portable radio communication device.
  • An antenna device for a portable radio communication device such as a mobile phone, a PDA, a portable computer and similar device, comprises a dielectric carrier 3, a flexible film 1 arranged on the dielectric carrier 3, and a radiating element arranged on the flexible film 1 on the side of the flexible film 1 that is positioned against the dielectric carrier 3, i.e. between the dielectric carrier and the flexible film 1.
  • a connector 5 of the antenna device comprises an upper portion 8 and a lower portion 6 foldable against each other.
  • the upper portion 8 is provided with engagement means 10, 11 for securing the upper portion 8 to the dielectric carrier 3 when mounted thereon.
  • the lower portion 6 is arranged to be positioned between the upper portion 8 and the dielectric carrier 3 when mounted thereon.
  • a flex-film radiator i.e. a flexible film 1 having a radiating element thereon
  • the connector 5 is first positioned on the dielectric carrier 3, Fig. 2 , and a contact tongue or contact portion 2 of the radiating element is positioned on the lower portion 6 of the connector 5, Fig. 3 . Thereafter the connector 5 is folded such that the engagement means 10, 11 of the upper portion 8 secures the connector 5 to the dielectric carrier 3, e.g. by snap fitting, Figs. 4-6 .
  • the flex-film radiator is preferably attached to the dielectric carrier 3 by means of an adhesive, such as a tape or glue.
  • the lower portion 6 is provided with resilient means 7 arranged to conductively connect to the radiating element when mounted on the dielectric carrier 3.
  • the resilient means 7, e.g. provided as a flexible tongue punched out of the lower portion 6, extends from the lower portion 6 towards the upper portion 8, and when the upper portion 8 and the lower portion 6 are folded together the resilient means 7 is urged towards the contact tongue 2 of the radiating element, which provides for reliable electrical contact.
  • the upper portion 8 preferably comprises a resilient means 9 for contact to a printed wiring board of the portable radio communication device, such as for grounding or feeding the antenna device.
  • the upper portion will preferably not have direct electrical contact with the contact tongue 2, due to the flexible film 1 on top of the radiating element. It is however also possible to provide the contact tongue 2 outside of the flexible film 1, to get direct electrical contact to both the upper portion 8 and the lower portion 6, but such a contact tongue 2 will be very sensitive for mechanical stress without the support of the flexible film 1.
  • the upper portion 8 of the connector can be used to connect both the inner and the outer radiating element to a common feed or a common ground.
  • the engagement means 7 is preferably provided by snap fitting into an aperture 4 in the dielectric carrier 3.
  • the engagement means is e.g. provided by means of two portions of the upper portion 8 bent essentially perpendicular thereto. Each bent portion comprises a first projection 10 arranged to be pushed into the aperture 4 and locked inside the dielectric carrier 3 on a shoulder of the aperture 4, and a second projection 11 being resilient essential perpendicularly to the locking of the first projection 10.
  • the aperture 4 is preferably shaped as a slot, having the first and second projections to lock to the inside of the dielectric carrier 3 on a shoulder of the aperture 4.
  • the first and second projections and the first and second projections could protrude out of the dielectric carrier and lock to the underside of the dielectric carrier.
  • Such a solution is preferably used when the connector 5 is positioned on the same side of the dielectric carrier as the radiating element, which position is described below.
  • the connector 5 is preferably formed by punching out a single shape of a sheet metal, which single shape thereafter is formed by bending the sheet metal to the desired connector.
  • the radiating element of the flexible film 1 By having the radiating element of the flexible film 1 arranged towards the dielectric carrier 3 it is further possible to mount discrete components on the radiating element, which are accommodated in indentations in the dielectric carrier, whereby they are provided together with the antenna device without increasing the height of the antenna device.
  • the connector 5 is illustrated as positioned in a recess in the underside of the dielectric carrier 3, or the side of the dielectric carrier opposite the side wherein the main part of the radiating element is arranged, whereby minimum height building of the antenna device is achieved.
  • the radiating element is also illustrated with portions thereof folded down over the circumferential parts of the dielectric carrier 3.
  • the contact tongue 2 is folded from the circumferential part into the connector 5. Further, if the radiating element does not include a folded down portion toward the connector 5 the contact tongue 2 is folded from one side of the dielectric carrier over the circumferential part into the connector 5.
  • the connector 5 could alternatively be positioned on the surface of the underside of the dielectric carrier 3, with only little height building of the antenna device, but still minimal height building of the connector 5.
  • the connector 5 has been described as positioned in the underside of the dielectric element 3 opposite the side wherein a major part of the radiating element is positioned, the connector 5 could also be positioned on the same side of the dielectric element 3 as the radiating element or be positioned on the circumferential side of the dielectric element, preferably in recesses thereof.
  • the resilient means 9 would in such a case need to be directed in another direction, compared to when the connector 5 is positioned on the underside of the dielectric element 3.
  • the connector 5 has been described having a resilient means 7 in the lower portion 6 thereof.
  • the connector instead has an alternative resilient means in the upper portion 8 thereof, which alternative resilient means is arranged to press the contact tongue 2 towards the lower portion 6.
  • the alternative resilient means will thereby press on the flexible film 1, which in it self will not create improved contact between the connector 5 and the radiating element, but the pressure will improve the contact between the lower portion 6 of the connector 5 and the contact tongue 2 to thereby create improve the contact between the connector 5 and the radiating element.
  • the antenna device can e.g. include any desired number of connectors, each formed and arranged according to the present invention.
  • the connector has been describe as positioned in an antenna device for a portable radio communication device, it may as well be used also for other devices such as e.g. an antenna device in a fixed radio communication device or any other device comprising a conductive element on a dielectric carrier.
