A measuring arrangement in the form of a measuring counter, a measuring slide or a measuring screw. The measuring arrangement comprises a housing in which a measuring unit, a transmission circuit and a receiving circuit are arranged on a common conductor plate. The transmission circuit and the receiving circuit use a common conductor plate antenna which is also provided on the conductor plate. A voltage supply circuit for supplying a voltage to the measuring unit, the transmission circuit and the receiving circuit is also arranged on the conductor plate. Via a measurement value sensor at the housing a measurement value is detected and converted by the measuring unit into an electrical measurement signal and transmitted via the transmission circuit wirelessly to an external central unit.
