Abstract
In this paper, we report on the waveguide-to-microstrip transition with an inline structure for the millimeter band. The waveguide-to-microstrip transition comprises a probe, an inductive line, a ${\lambda}/4$ impedance transformer, and a 50-ohm microstrip line. For the transition design, we optimized the characteristic impedances and lengths of the component parts. The fabricated transition exhibits an insertion loss of 2.1 dB and an input/output return loss of below 13 dB at a millimeter band frequency of 94 GHz.
