In this paper, an ultra-wideband self-packaged SISL to GCPW transition is studied and designed. A new structure from stepped impedance to two-stage gradient is proposed to solve the problems of impedance mismatch and parasitic mode caused by structural discontinuity between SISL and GCPW direct interconnection. Compared with the direct interconnection structure, the proposed SISL to GCPW transition has the advantages of wideband and lower insertion loss. The final simulation results show that the return loss |S11| of the transition structure achieves better than 20 dB and the average insertion loss |S21| is 0.35 dB over DC to 40 GHz.
