Design of a Cost-Efficient Monostatic Radar Sensor With Antenna on Chip and Lens in Package

This work presents a ${D}$ -band monostatic radar system operating from 144.6 to 161 GHz, which is placed inside 3-D-printed low-cost case with built-in lens boost the antenna (ANT) directivity. The monolithic microwave integrated circuit (MMIC) manufactured in 130-nm BiCMOS process and includes compact transceiver architecture consisting of an oscillator, diode-based mixer, on-chip antenna. implemented topology allows significantly improve signal-to-noise ratio features self-test (BIST) structure possibility provide characterization using power sensors combination directional coupler. Housed robust printed package, MMIC has only dc baseband frequency connections, offers ease handling poses potential for variety applications. complete chip consumes 84.7 mA 3.3-V supply its size 1964 notation="LaTeX">$\mu \text{m}\,\,\times1448\,\,\mu \text{m}$ .
