Carrier element for supporting at least one medical or dental instrument in a cleaning or care device

A carrier element for supporting at least one medical or dental instrument in a cleaning or care device for cleaning or caring for the at least one medical or dental instrument, the carrier element comprising:

• a passive data and/or energy transmission unit having at least one coupling antenna provided on the carrier element and configured to receive electromagnetic radiation comprising data and/or energy transmitted wirelessly between a first transmitting and receiving unit arranged on the medical or dental instrument and a second transmitting and receiving unit remote from the first transmitting and receiving unit, and
• wherein the at least one coupling antenna is configured to emit the received electromagnetic radiation again in order to support the wireless transmission of the electromagnetic radiation comprising data and/or energy between the first transmitting and receiving unit and the second transmitting and receiving unit,
• wherein the at least one coupling antenna is formed by an opening in a wall of the carrier element, wherein the opening is a slot to form a slot antenna, wherein the at least one coupling antenna is a first coupling antenna and wherein the passive data and/or energy transmission unit of the carrier element comprises at least one additional coupling antenna, wherein the at least one additional coupling antenna comprises a linear antenna, wherein the linear antenna is disposed in the opening which forms the first coupling antenna.

A carrier element for supporting at least one medical or dental instrument in a cleaning or care device for cleaning or caring for the at least one medical or dental instrument, the carrier element comprising:

• a plurality of coupling antennas provided on the carrier element and configured to receive electromagnetic radiation comprising data and/or energy transmitted wirelessly between a first transmitting and receiving unit arranged on the medical or dental instrument and a second transmitting and receiving unit, and
• wherein the plurality of coupling antennas is configured to emit the received electromagnetic radiation again in order to support the wireless transmission of the electromagnetic radiation comprising data and/or energy between the first transmitting and receiving unit and the second transmitting and receiving unit, wherein
• the plurality of coupling antennas comprises a first coupling antenna and a second coupling antenna, which are different coupling antennas, wherein
• the first coupling antenna comprises a slot antenna formed in a first wall of the carrier element and a second coupling antenna comprises a slot antenna formed in a second wall of the carrier element, wherein the first wall and the second wall are different walls of the carrier element that are parallel to one another or that are arranged at an angle to one another with the angle not equal to 0°.
