The invention relates to a passive repeater for forwarding radio signals from a first device having a radio interface to a second device having a radio interface, wherein the passive repeater is configured to forward radio signals between an interior of a housing, which has a housing wall acting as a radio barrier, and an exterior, through the housing wall, wherein the passive repeater has a first antenna and a second antenna for this purpose, which are connected to each other by a passive and galvanic coupling, and wherein the first antenna can be arranged in the interior and the second antenna can be arranged in the exterior, and the passive coupling can be carried out through an opening in the housing wall, and wherein the first antenna can be inserted into the interior from the exterior through the opening and/or the second antenna can be withdrawn from the interior to the exterior through the opening. The invention further relates to a radio system having such a passive repeater, to a vehicle having such a repeater or such a radio system, to a bearing having such a repeater or such a radio system, and to a use of such a repeater or such a radio system.
A passive repeater for forwarding radio signals from a first device with a radio interface to a second device with a radio interface, wherein the passive repeater is designed to forward the radio signals between an interior of a housing that has a housing wall acting as a radio barrier and an exterior through the housing wall, the passive repeater comprises a first antenna and a second antenna which are connected to each other by a passive and galvanic coupling, the first antenna is arrangeable in the interior and the second antenna is arrangeable in the exterior and the passive and galvanic coupling is realized through an opening in the housing wall, wherein the first antenna is insertable from the exterior through the opening into the interior or the second antenna is led out from the interior through the opening to the exterior, and one of the antennas or both of the antennas are formed from an elastic material and are configured to move from (a) a folded configuration during insertion through the opening to (b) an unfolded configuration after insertion through the opening.
A radio system with a first device with a radio interface and a second device with a radio interface, the radio system comprising a passive repeater, and the first device with the radio interface and the second device with the radio interface exchange data via the passive repeater,
A passive repeater for forwarding radio signals from a first device with a radio interface to a second device with a radio interface, wherein the passive repeater is designed to forward the radio signals between an interior of a housing that has a housing wall acting as a radio barrier and an exterior through the housing wall, the passive repeater comprises a first antenna and a second antenna which are connected to each other by a passive and galvanic coupling, the first antenna is arrangeable in the interior and the second antenna is arrangeable in the exterior and the passive and galvanic coupling is realized through an opening in the housing wall, wherein the first antenna is insertable from the exterior through the opening into the interior or the second antenna is led out from the interior through the opening to the exterior, and one of the antennas or both of the antennas are formed from an elastic material, wherein the housing is a bearing housing and the first antenna is arranged in the interior of the bearing housing and the second antenna is arranged in the exterior and the passive and galvanic coupling is realized through the opening that is located in a bearing housing wall.
