Definitions

  • the invention relates to a walkie-talkie with a transmitter / receiver and an associated device antenna.
  • Two-way radios have a wide range of uses, particularly as end portables in mobile telephone systems.
  • the physiological influence on the human body that occurs in the relevant frequency ranges is increasingly being addressed.
  • the problem is that a hand-held portable device radiates into the user's head with a normal operating position on the head and an antenna with a radiator length of approximately 80 mm.
  • the head acts as a shadow for the radiation of the antenna.
  • the invention has for its object to provide a solution with which these problems can be easily eliminated.
  • This object is achieved in a radiotelephone of the type described at the outset according to the invention by increasing the base of the effective antenna in such a way that the antenna consists of a non-radiating part connected to the device housing made of plastic (spacer) and a self-radiating part connected to it.
  • the antenna radiator is located above the top edge of the head and thus only exerts an insignificant physiological influence.
  • the antenna can develop its optimal directional characteristic.
  • Figure 1 shows an embodiment with a pivotable antenna.
  • the antenna consists of an elongated, non-radiating antenna base 2 (spacer) and a radiating antenna part of, for example, ⁇ / 2 length.
  • the antenna is attached to the side of the device housing 1 and can be pivoted via a joint 4. By swiveling the antenna in the direction of the arrow, it can be brought into a position on the side of the device housing in the rest position (dashed line).
  • Figure 2 shows an embodiment with a double-joint antenna (folding antenna).
  • the first antenna joint part 2 is a spacer, while the second joint section 3 represents the effective part of the antenna (radiator).
  • the entire antenna construction is detachably connected via a coaxial swivel joint 4 to the device housing 1, which is only partially shown in the figure.
  • a latching coaxial swivel joint 5 is attached between the first and the second part (spacer 2 and radiator 3).
  • the antenna is fully integrated into the housing design in the folded state (the spacer 2 lies on the top of the device, the radiator 3 on the left side of the device housing in the figure). This allows the device to be transported optimally. Damage during transport (e.g. in a bag) is largely avoided.
  • the antenna In this folded-in state, the antenna has limited functionality.
  • the radiator 3 By a rotation of the radiator 3 by 180 o, the "stand by" position of the antenna achieved.
  • the radiator 3 is in a position that extends the left side of the device housing. In areas with a good network infrastructure, calls can also be made in this antenna position if, for example, the radio is parked on a platform.
  • the antenna can also be designed as a telescopic antenna which has an elongated, non-radiating foot and can be inserted into a recess in the longitudinal direction of the device housing.
  • the antenna can also be designed as a screw-on or plug-on version.
