This paper presents a topology optimization approach to design planar
transitions between a microstrip line (MSL) and a rectangular waveguide
(RWG) in the K-band. The transition comprises two sub-transitions: one
from the MSL to a substrate integrated waveguide (SIW) and the second
from the SIW to the RWG. Both are on the same substrate and can be
manufactured with a standard printed circuit board process. This leads
to a very cost-effective solution compared with other approaches. A
WR-42 waveguide can easily be surface mounted to the transitions using a
standard flange. The transitions have been fabricated, and their
measured performance shows good agreement with the simulations. The
MSL-SIW transition has a broadband behavior and the SIW-RWG transition
still reaches a relative bandwidth of 10%.
