Packaging and interconnect solutions for a low cost surface-mountable millimeter-wave radar sensor

This paper introduces the idea of a low-cost surface-mountable millimeter-wave radar sensor. Different packaging topologies are compared with the aim of realizing a complete system-in-package. Finally, two different possibilities of interconnecting a Silicon MMIC with an off-chip antenna are evaluated based on simulations and measurements within the frequency range from 110 GHz to 170 GHz.
