Abstract
Device for transmission of electromagnetic radiation through a wall. In order to couple transmission-reception means (2, 4) located on each side of the wall (6), this device comprises two antennas (12, 14) placed on each side of this wall and connected to each other through this wall. Electromagnetic protection means (20) are arranged on all or some of the surfaces of the wall facing the antennas and are made of an electrically conducting material. This device is particularly applicable to a transmitter-receiver system for which one of the components is in a slightly conducting container.
Claims7
Device for transmission of an electromagnetic radiation, particularly a radio frequency radiation, this device comprising:
- first means (2) for transmission and/or reception of said electromagnetic radiation,
- second means (4) for reception and/or transmission of said electromagnetic radiation, these second means being separated from the first means by a wall (6), and
- passive electromagnetic coupling means (32) between the first and second means, these passive electromagnetic coupling means comprising first and second antennas (12, 14) which are placed on each side of the wall, and means of making an electrical connection (16) between the first and second antennas, these electrical connecting means passing through the wall,
- this device being characterized in that it also comprises electromagnetic protection means (20) arranged on all or some of the surfaces of the wall facing the first and second antennas, these electromagnetic protection means being made of an electrically conducting material.
