Abstract :
Compact and low-radiation CPW probe pads using CBCPW-to-microstrip transitions are demonstrated for V-band LTCC applications. To reduce the radiation loss due to open-end and transition discontinuities, a vialess CBCPW and back pad are designed. The back pad and an optimum transition length suppress the radiation loss due to discontinuities by 30 and 10 %, respectively, compared to a conventional vialess transition. In particular, the radiation loss of the designed transition is suppressed completely at 66 GHz and its S21 is -0.15 dB at that frequency
