The invention relates to a waveguide arrangement for guiding electromagnetic waves, which comprises a rectangular waveguide and a circular waveguide. The rectangular waveguide merges into the circular waveguide at an angle. The circular waveguide is filled with a dielectric which projects into the rectangular waveguide in a transition section. The dielectric filling is beveled at a defined angle in the transition section so that a transition surface is formed by the inner edge at the transition of the waveguide arrangement and the end face of the rectangular waveguide at the transition. The dielectric filling is preferably flush with the closing wall of the rectangular waveguide.

Waveguide device and antenna

An antenna assembly for a level radar for detecting a topology of a filling material surface is provided. For example, the antenna assembly comprises antenna elements which are designed and/or configured to transmit and/or receive the electromagnetic measurement signal. The distances between adjacent elements are non-equidistant with respect to one another, and the minimum distance between two elements can correspond to one half of a wavelength of the electromagnetic measurement signal.

Antenna assembly for a level gauge

Exemplary waveguide coupling configuration can be provided for a fill level radar antenna, e.g., in the form of a line scanner. The exemplary waveguide coupling configuration can include a waveguide openings on the antenna side which can have a distance from one another that can correspond to less than or equal to one half of the wavelength of the transmission signal. For example, the distance between adjacent radiator elements can be greater than one half of the wavelength of the transmission signal. In this exemplary manner, more space can be provided for a front end on the printed circuit board.
