An Integrated On-Chip SiGe Antenna in Dual 79 GHz and 140 GHz Bands for Automotive Sensing Applications

Sensing capabilities and specifically high resolution radars are fundamental in the development of increasingly autonomous vehicles. However, these kind of sensors require high bandwidths, pushing their development towards mm Wave, which present complications in the integration of chips and antennas. In this paper, a dual-band, on-chip, integrated antenna is presented to operate in the 79 GHz and 140 GHz range, crucial for current and upcoming automotive sensing applications. First, an ideal design is implemented in IHP's SiGe 130nm technology, then the design is optimized taking into consideration specific design rules of the technology to yield a fully manufacturable modular antenna.
