Abstract

A measuring carrier for position-resolved meteorological determination of a measurement variable dependent on the dielectric permittivity of a device under test. The measuring carrier has a supporting means comprising a measuring surface, to which the device under test can be applied, and a measuring transmission line which entirely or partially forms the measuring surface and comprises a multiplicity of transmission line cells for the purpose of transmitting a radio-frequency measurement signal which can be injected at the input port. The measuring surface is structured in a cellular manner, wherein each of the transmission line cells has a cell-individual propagation constant with respect to the radio-frequency measurement signal in a state free of a device under test. This constant differs from the respective cell-individual constants of the other transmission line cells.
