Definitions

• the invention relates to a system with a slot waveguide for data transmission.
• Shielding plate is at least partially slipped over the chimney portion, in particular from the outside, that is slipped over from the outer environment of the slot waveguide ago.
• an antenna part projecting into this slot area can be easily coupled.
• the shielding plate further arranged in the system radiation sources such as wireless devices, mobile devices or the like, can be shielded, so that the error rate at
• CONFIRMATION COPY the data transmission between the antenna and the slot waveguide decreases and therefore again a high data transmission rate is made possible.
• Rail direction at least the length of the antenna.
• the shielding plate is connected to the rail vehicle.
• the advantage here is that only a short track length in the rail direction must be shielded.
• the antenna is connected to an electrically insulating holding part, wherein the shielding plate is connected to the holding part.
• the antenna extends in the transverse direction, ie transversely to the rail direction.
• the advantage here is that the antenna protrudes from below into the slot, which is open in the downward direction of gravity. Thus, no liquid can accumulate in the slot waveguide and pollute it.
• Shield plate less than half or even less than a quarter of the wavelength of the coupled from the antenna in the slot waveguide or decoupled
• the advantage here is that a very strong attenuation of the interference is possible.
• the shield plate made of copper, aluminum or steel, in particular as a stamped and bent part.
• the advantage here is that due to the good electrical conductivity effective damping is possible.
• FIG. 2 shows an associated oblique view.
• Slot waveguide is executed.
• the antenna 4 of the rail vehicle protrudes at least partially into the slot of the slot waveguide and electromagnetic wave components can be coupled or decoupled. In this way the data transfer is possible.
• the antenna is held by an electrically insulating holding part 5 of the rail vehicle.
• a shield plate 3 is fixed, which is designed to shield from other electromagnetic radiation sources.
• the shroud 3 has a U-shaped profile in cross section, wherein the normal direction of the cross-sectional plane in the rail direction or
• Conductor direction of the slot waveguide is aligned.
• the shield plate In and against the rail direction, the shield plate is open on both sides, so that the rail vehicle is freely movable.
• the shielding plate 3 is preferably made of copper, steel and / or aluminum.
• the slot is surrounded by a chimney section 2, which limits the slot opening transversely to the rail direction quasi collar-shaped.
• the shroud 3 covers the chimney section 2, ie the collar, seen from the outside in the transverse direction, ie in a direction which is transverse to the rail direction and transverse to the
• the shroud 3 surrounds the chimney section 2 from the outside at least partially.
