The present disclosure relates to a transition arrangement (1) for transitioning between a transmission line, TL (2), and a substrate integrated waveguide, SIW (3), for routing a microwave signal. The transition arrangement (1) comprises a block of dielectric (4) comprising a first layer (5) comprising the TL (2) having a length (L) extending in a first direction (x1) towards the SIW (3). The TL (2) comprises a plurality of sections (S1, S2, S3, S4) having gradually increasing widths (W1, W2, W3, W4) along the first direction towards the SIW (3), wherein the widths (W1, W2, W3, W4) are defined in a second direction (y1) being perpendicular to the first direction (x1). Further, each section (S1, S2, S3, S4) is associated with at least one corresponding TL ground plane (7) in a layer parallel to the first layer (5). For each increase in width (W1, W2, W3, W4), each corresponding TL ground plane (7) defines an increasing distance from the TL (2) in a third direction (z1) being perpendicular to the first and the second direction (x1, y1). Furthermore, the block of dielectric (4) comprises a fence structure (8) arranged on opposing sides of the TL (2) and extending along at least a portion of the TL (2) towards the SIW (3) in the first direction (x1), at least a part of the fence structure (8) having a spacing of less than half a wavelength of the microwave signal in the second direction (y1).
