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. |
