Definitions

  • the invention relates to a hand-help apparatus comprising antenna means for emitting a radio signal, and to such an apparatus comprising a shield which consists of an insulating material and surrounds some of the electronic componentss of the apparatus, and which is metallized on the side facing away from the components as well as on the side facing the components in order to shield radio frequency signals.
  • the portable transmitter and receiver units are usually provided with antennas which have an omnidirectional radiation diagram, as this gives the greatest possible probability that a connection is established to the mobile telephone concerned at a given time, thereby facilitating the system planning of the system operators.
  • antennas which have an omnidirectional radiation diagram, as this gives the greatest possible probability that a connection is established to the mobile telephone concerned at a given time, thereby facilitating the system planning of the system operators.
  • the users of the mobile telephones wish that the system has a coverage as good as possible.
  • the omnidirectional radiation diagram has the drawback that the telephone will usually be arranged in such a manner with respect to a user's head that the head is present precisely where the electrical field from the antenna of the telephone is strongest. This means that a certain power loss will occur, as a part of the radiation energy dissipates in the head, and also involves the risk that precisely this energy dissipation may constitute a health hazard. Because of the possible health hazard in particular, it is therefore desired that the radiation should be directed away from the user's head.
  • the radiation is mainly directed away from the user's head, the transmission/reception conditions of the telephone will moreover be impaired, unless a base station is present precisely in this direction. Therefore, the solution is useful only in areas where the base stations are located so close to each other that there will always be a sufficiently close base station in the direction concerned.
  • US 5 530 919 e.g., describes an apparatus which has a built-in directional antenna and a rod antenna.
  • the directional antenna is used as a transmitter antenna and the rod antenna as a receiver antenna.
  • This apparatus too, therefore relies on the presence of a base station in the direction in which the directional antenna is oriented, as the apparatus can only transmit in this direction.
  • the rod antenna enables reception from all directions.
  • EP 214 806 describes an apparatus with a built-in directional antenna and a rod antenna. Both antennas are used here as receiver antennas in order to obtain receiver diversity, while only the rod antenna is used as a transmitter antenna. Thus, this apparatus does not avoid radiation into the user's head.
  • US 5 530 919 discloses an apparatus which has an incorporated antenna and a shield which is disposed between the antenna ant the user's head. However, they are two separate components which therefore still take up some space. Accordingly, a further object of the invention is to provide an apparatus having a built-in patch antenna which takes up less space than in the known devices.
  • the apparatus as statet in claim 1, comprises a shield which surrounds some of the electronic components of the apparatus and consists of an insulating material metallized on the side facing away from the components as well as on the side facing the components, in that at least part of the metallization facing away from the components constitutes a patch antenna which is adapted to transmit and/or receive said radio signals.
  • devices of this type will be provided with a shield against radio frequency signals.
  • It will usually be a metallized plastics shield which is metallized on both sides for reasons of production, so that in fact it is a double shield.
  • the inner side of the shield can still serve the function of a shield against radio frequency signals, as stated in claim 2, while constituting the ground plane associated with the patch antenna.
  • the desired radiation diagram is achieved in that the patch antenna, like in claim 3, is disposed on the side of the apparatus which, when used by a person, faces away from the person. For a mobile telephone, this will be the rear side of the telephone.
  • the directional effect is achieved because the other metal parts and printed circuit boards of the telephone perform a shielding effect toward the person.
  • a printed circuit board 1 mounts a plurality of electronic components 2, and owing to incident and emanating radiation of radio frequency signals the components are surrounded by a shield 3, which typically consists of a plastics material 4 provided with a metallization 5, 6 on both sides.
  • a shield 3 typically consists of a plastics material 4 provided with a metallization 5, 6 on both sides.
  • Metallization on one of the sides will normally be sufficient to perform the shielding function; but, generally, the shield will be metallized on both sides for reasons of production. This means that the metallization on the outer side may be used for other purposes.
  • Fig. 2 It is shown in fig. 2 how this may be utilized for a patch antenna according to the invention.
  • the metallization 6 is still present on the inner side of the plastics material 4, while the metallization 5 from fig. 1 on the areas 7 and 8 is removed.
  • the metallization constitutes a patch antenna 9 on the central part of the outer side.
  • This patch antenna inter alia because of the shielding metallization 6, will particularly radiate radio frequency signals in a direction away from the plastics material 4 and thereby away from the components 2.
  • the printed circuit board 1 itself and the other metal parts of the telephone will provide a further shielding effect in the opposite direction.
  • FIG 3 shows that when the shield 4 with the patch antenna 9 is placed on the rear side 10 of a telephone 11, a radiation diagram is obtained where the radiation 12 is directed away from the person 13 who uses the telephone. It will be seen that the telephone 11 is also provided with a rod antenna 14 which, in this situation, is not connected and therefore does not emit radio signals.
  • the rod antenna 14 may be arranged as a telescoping antenna which is connected only when it is extended. In that case, it has an omnidirectional radiation diagram, which means that when it is extended, the telephone 11, generally speaking, emits (and receives) radio signals equally well in all directions, and thus also in the direction of the person 13. The idea is thus that in areas having sufficient radio coverage, the radiation 12 from the patch antenna 9 will be sufficient to ensure connection, as there will usually be a sufficiently close base station in the direction of the radiation 12. The telescoping antenna 14 may thus be retracted and thereby be disconnected. Then, the person 13 will not be exposed to the strong radiation from the telephone. This corresponds to the situation shown in fig. 3.
  • the antenna 14 may then be extended and thereby connected so that the telephone 11 has the omnidirectional radiation diagram with the radiation 15.
  • the person 13 is exposed to radiation in the same manner as in ordinary mobile telephones which are just provided with an omnidirectional antenna; but, as mentioned, this will just be the case where the radio coverage is not very good.
  • the radio coverage in urban areas will usually be sufficient for the situation in fig. 3 to be used, thereby avoiding exposing the person to the incident radiation, while outside the urban areas it will typically be necessary to supplement with the telescoping antenna and the associated incident radiation of radio energy. For the great majority of subscribers, the radiation to which they are exposed will thus be reduced considerably.
  • Fig. 5 shows a block diagram for an alternative embodiment.
  • the signal to and from the antenna 4 is here connected to the transmitting/receiving circuit 16 of the telephone via a switch 17.
  • a detecting circuit 18 can measure the field strength of a signal received on the patch antenna 9 and control the switch 17 in response thereto. If the field strength is above a predetermined threshold value, the connection between the antenna 14 and the transmitting/receiving circuit is disconnected, while, correspondingly, this connection is established when the field strength of the received signal is below this threshold value.
  • the antenna 14 is connected only when the signal received on the patch antenna 9 is too low to ensure a good connection.
  • the antenna 14 is a telescoping antenna, the full effect of this principle is achieved only if the antenna is extended, of course.
  • a special signal may be transmitted from the base station to the telephone if the signal received therefrom is too weak, and the detecting circuit 18 may then be adapted to receive this signal and control the switch 17 in response thereto.
  • the signal received on the base station that decides whether it is necessary to connect the omnidirectional antenna 14.
  • the coaxial cables may be replaced by two patch antennas arranged opposite to each other, as will be seen in fig. 6.
  • the holder 20, also called cradle, of the telephone is provided with a patch antenna 19 whose size corresponds to the size of the patch antenna 9 in the telephone, and which is arranged so that it will be right opposite it when the telephone is placed in the holder.
  • the patch antenna 19 is connected to the external antenna by means of the cable 21.
  • the holder 20 may moreover be provided with e.g. guide rails capable of ensuring that a telephone is always placed in the holder such that the two patch antennas are right opposite each other and at a well-defined distance from each other.
  • the radio frequency signals are thus transferred wirelessly between the two patch antennas. This means that the coaxial connectors may be saved, while obtaining a solution which is not subjected to wear, as is the case with the coaxial connectors.
