An integrated laminated waveguide (LWG) to
metallic rectangular waveguide (RWG) transition based on low
temperature co-fired ceramic (LTCC) technology is presented in
this paper. The transition is designed for the 76 − 81 GHz radar
frequency band using a high permittivity material (er = 7.4). An
additional secondary LWG structure improves both impedance
matching and bandwidth. The bandwidth at − 10 dB return loss
is more than 5 GHz. The measurement results of the fabricated
prototype agree closely with the simulation. This compact and
backshort-free waveguide transition allows low-cost integration
and offers the possibility of measuring E-Band radar components
based on ceramic substrate.
