发明名称 Removable cover for roof of motor coach of duplex high speed train, has housing delimited in extension defined by sidewalls to receive satellite antenna of waves, where portions of sidewalls and top are manufactured from composite material
摘要 The cover (20) has sides (42, 44) inclined with respect to a top (40), and lateral sidewalls and bottom being opened, where the cover is fixed to a roof of the vehicle to form a continuous surface with the roof. A portion of the top and/or a portion of the sidewalls are manufactured from a material i.e. thermosetting matrix composite material, transparent to electromagnetic waves having a range of frequencies greater than 2 GHz. A housing is delimited by the cover in an extension defined by the sidewalls to receive a transmission antenna i.e. satellite antenna, of the waves. An independent claim is also included for a railway vehicle.
