Definitions

  • the FM band is defined as frequencies between 88-108 MHz in Europe or between 76-110 MHz in the USA.
  • One internal antenna operable in the FM band is a so-called active antenna, where a half-loop radiating element in the interior of a portable radio communication device is used together with a high-impedance low-noise amplifier.
  • Such an antenna device is for instance known from WO
  • the invention is based on the realization that the cover of a portable electronic device can be used as a radiator element of an active antenna as well as for electrostatic discharge protection.
  • an antenna device for receiving radio signals in at least one operating frequency band and for being provided in a portable electronic device equipped with a cover.
  • the antenna device comprises a radiator element provided with a first antenna connection point, a matching element connected between the radiator element and ground at least one electrostatic discharge protection unit connected between the radiator element and ground and an amplifier stage connected to the first antenna connection point, where an output of the amplifier stage is connectable to a radio circuit.
  • a portable electronic device comprises a cover, a radiator element provided with a first antenna connection point, a matching element connected between the radiator element and ground, at least one electrostatic discharge
