摘要:
Portable device for receiving and/or transmitting radio-transmitted messages comprising:a case (11; 42; 51),an antenna (12; 31, 32; 52, 53) capable of picking up both a magnetic component and an electric component of an electromagnetic field carrying radio-transmitted messages, anda micro-receiver (13) receiving the messages picked up by the antenna, said antenna comprising two conductive plates (15, 16; 31, 32; 52, 53) disposed so as to pick up the radial electric component (E.sub.r) of said electromagnetic field with respect to the body of the wearer.The antenna (12; 31, 32; 52, 53) is formed by a coil (17) comprising a turn arranged in said case (11; 42; 51) to pick up the azimuthal magnetic component (H.sub..PHI.) of said electromagnetic field around said body and the plates (15, 16; 31, 32; 52, 53) form part of said coil (17).
