Reception - and / or transmitting device for radio messages with an inductive and capacitive antenna

摘要

Reception device and / or of transmission of a portable radio broadcast messages comprising: & br / - a housing (11; 42, 51), & br / - an antenna (12, 31, 32 and 52, 53) adapted to receive a magnetic component and an electrical component of an electromagnetic field bearing radio diffused messages, and & br / - a micro receiver (13) receiving the messages picked up by the antenna, & br / said antenna including two conductive plates (15, 16; 31, 32 and 52, 53) in order to pick up the radial electrical component (er) of the electromagnetic field with respect to the body of the wearer. & br / the antenna (12, 31, 32 and 52, 53) is constituted by a coil (17) comprising a coil disposed in said housing (11; 42, 51) in order to collect the magnetic component azimuthal phi (h) of the electromagnetic field around the body and the plates (15, 16; 31, 32 and 52, 53) form part of this coil (17).
