Abstract :
Today, SiGe HBT cut-off frequencies are higher than 230 GHz (Chevalier et al., 2004) and this increase allows new millimeter wave (MMW) applications on silicon such as 60 GHz WLAN and 77 GHz automotive radar. One of the success keys is then the passive integration. This study focuses on a 52 GHz silicon integrated antenna and related feeding transmission line (TL) topics. Double slot antenna integrated in a standard BiCMOS process and 40 GHz coplanar patch antenna (2.3dB gain @ 40 GHz) with a coplanar waveguide (CPW) feed line are depicted and characterized. Integrated TL achieved on standard STMicroelectronics (ST) BiCMOS, CMOS and silicon on insulator (SOI) technologies are described, performances are given (<0.7 dB/mm losses @ 80 GHz for SOI CPW). A full modeling has been developed up to 80 GHz with new approach for CPW on silicon technology due to passivation layer.
