Original Kurzfassung:
A differential microstrip line (DMSL) to laminated
waveguide (LWG) transition based on low temperature co-fired
ceramic technology is presented in this paper. The transition is
designed for the 76 ? 81 GHz radar frequency band using high
permittivity material (er = 7.4). The achieved bandwidth at 10 dB
return loss is more than 10 GHz. For measurement purposes,
another metallic rectangular waveguide to LWG transition was
designed and cascaded with the DMSL-to-LWG transition. The
measurement results of the fabricated prototype agree closely
with the simulation. The designed transition simplifies the
application of monolithic microwave integrated circuits with
differential outputs and enables low-cost integration of W-band
radar components on ceramic substrate.
