The invention relates to a device for determining at least one parameter of at least one medium, said medium being introducible into at least one measuring path. An electric and/or electromagnetic field can be partially coupled into or out of the medium by passing at least one electric and/or electromagnetic signal into the measuring path. The measuring path comprises at least one line arrangement having at least two elementary cells arranged along the measuring path, said elementary cells comprising at least one electric path from at least one input to at least one output and comprising at least one respective capacitative element. The electrical properties of the capacitative element can by be modified by the medium. The electric and/or the electromagnetic signal can be applied to the input of a first elementary cell and the output of the first elementary cell can be connected to the input of a second elementary cell. The capacitative element of the respective elementary cell is arranged in the electric path of the first and second elementary cell. At least one inductive element connects the first elementary cell and the second elementary cell to a ground. The invention also relates to a method for determining a parameter of a medium.

An antenna arrangement for coupling high frequency electromagnetic waves into or out of a pipe-shaped hollow body includes two patch antenna elements that are located opposite one another and integrated in the pipe inner wall () of the hollow body (), and have curved surfaces fitted to the curved longitudinal pipe inner wall of the hollow body (). An apparatus for mass flow measurement includes at least two of such antenna arrangements axially spaced apart from one another in a conveyor pipe section.
