Definitions

  • the invention relates to a radio of the type described in the preamble of claim 1, which consists of e.g. EP-A-0 372 720 is known.
  • Radio equipment has a wide range of uses, especially as a handheld portable 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 radio radiates into the head of the user with the head in normal operating position 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 eliminated in a simple manner and the rod antenna is at the same time space-saving and protected.
  • the antenna rod consists of a hollow cylindrical, non-radiating spacer which can be folded or folded into the housing of the device and a radiator which is guided telescopically in the spacer, and that the radiator is coiled Coaxial line is connected as a supply line, which is stretched when the telescopic rod is pulled out.
  • the spacer is advantageously guided in a sleeve-shaped guide part on the inside of the housing.
  • the handheld radio shown in FIGS. 1 and 2, which is denoted overall by 1, has a rod antenna which is divided into a radiating part 3 (radiator) and a non-radiating part 4 (spacer).
  • the spacer 4 consists of a hollow cylinder which is slidably guided in a sleeve-shaped guide part 2 on the inside of the housing of the device 1.
  • the spacer is provided with a flange 5, which serves as a stop on the underside of the sleeve-shaped guide part 2 when the rod antenna is pulled out.
  • the radiator 3 is telescopically displaceable in the spacer 4.
  • the lower part of the radiator 3 has an enlarged diameter, so that the step-shaped heel thus formed, when the rod antenna is pulled out, forms a stop on an inwardly directed flange 6 of the hollow cylindrical spacer 4.
  • a coiled line 7 serves as a lead to the radiator 3 which is stretched when the telescopic rod is pulled out.
  • the device is fed in via e.g. Feed element 8 designed as a transformer.
  • the coupling into the transmitting part can thus take place via simple plug-in elements.
  • the radiator and spacer are sunk one into the other and overall in the housing (see FIG. 1).
