The present disclosure relates to a waveguide transition arrangement (300, 700) for coupling a signal between a transmission line (120, 320) and a waveguide aperture (112, 312, 712) The transition arrangement (300) comprises - an electrically conductive backshort (319, 719), - a first layer structure (103, 703) comprising a first dielectric carrier material (104) and a first metallization layer (105), and - a second layer structure (106, 306, 706) comprising a second dielectric carrier material (107, 307), a second metallization layer (108, 308), a trench (109, 309, 709) provided with electrically conductive trench walls (110, 111; 318), and a waveguide aperture (112, 312, 712) that is connected to the trench (109, 309, 709), comprises electrically conductive inner waveguide walls (321), and defines a waveguide that has a signal propagation extension (E) into the second layer structure (106, 306, 706). The first metallization layer (105) comprises a probe (116, 116A), a first signal conductor (113, 133A), and a pair of beamlead conductors (114A, 114B) on each side of the first signal conductor (113, 113A) and an end of the first signal conductor (113, 133A) is connected to the probe (116, 116A). The second metallization layer (108, 308) comprises trench side conductors (115A, 115B; 315A, 315B) on opposite sides along the trench (109, 309, 709), and an aperture conductor (117, 317) that partially circumvents the waveguide aperture (112, 312, 712). The beamlead conductors (114A, 114B) are connected to the respective trench side conductors (115A, 115B; 315A, 315B) such that the first signal conductor (113, 113A) runs along to the trench (109, 309, 709), and the probe (116, 116A) can couple the signal between the transmission line and a waveguide.
