Patent ID: 8547285

Claim:
A unit including a glidepath aerial and a support member constructed with a landing gear mounting area to be mounted on the front landing gear of an aircraft, with the landing gear mounting area comprising a point of contact and connection for the support member directly to the landing gear, and with said landing gear forming an electrically conductive ground plane, wherein: said aerial is mounted on an aerial mounting area of said support member by being electrically insulated from said support member by insulating elements, said support member has a longitudinal dimension from the point of connection of the aerial at the aerial mounting area to a point of attachment of the landing gear at the landing gear mounting area of said support member at least equal to around one quarter of the wavelength λ at which said aerial functions, so that the distance separating said aerial and said ground plane formed by the front landing gear is greater than λ/4, and said aerial also has a transmission line intended to connect said aerial to a receiver in the aircraft; said transmission line is surrounded by an electromagnetic shielding element serving as a faradizations screen for said transmission line, with said element designed to be electrically connected to said ground plane.
