Abstract
The project emphasizes at two parts: one is the transition from the Coplanar
Waveguide (CPW) to the rectangular waveguide (RWG) and the other is the flip-chip
transition. The transitions designed in the first year are realized in the Ka- and
Q-bands in the second year. The measurement results show reasonable agreement
with the simulation results. For the CPW to RWG transition, the transition realized in
the Q-band has a bandwidth of 40% in which the return loss is better than 15dB.
Compared with the traditional CPW to RWG transition, the bandwidth is very large
and the size is small. Also, the idea is extended to the V-band and a bandwidth of 16%
in which the return loss is better than 15dB is obtained. The smaller bandwidth is
limited by the Al2O3 substrate of high dielectric constant. For the improved flip-chip
transition, the return loss is larger than 20 dB in the frequency range from DC to 35
GHz, demonstrative of really a wideband design.
