Abstract
A device for transmitting or emitting high-frequency waves includes: a microstrip line (10) with one end (10′) in a substrate (11) for transmitting high-frequency useful signals; a first ground surface (12) and a second ground surface (13), which are provided on opposite sides of the microstrip line (10), for forming a TEM waveguide assembly; an opening (14) in the first ground surface (12) located at a predefined distance (d) from the end of the microstrip line (10′) for decoupling a high-frequency signal; a feedthrough device (15) for conductively connecting the first ground surface (12) with the second ground surface (13) on the lateral periphery of the microstrip line (10); and a planar coupling device (16) for receiving and transmitting or emitting the high-frequency useful signal. The feedthrough device (15) is configured in such a way that at a given frequency (f) it prevents the propagation of waveguide modes and excitation of waveguide mode resonance in the useful frequency band (F).
