2.2.2 PCB and Form Factor

The goal of this reference design is to have a small compact radar module which is easy and ready to use for the in-cabin applications. With the mounting holes, the board measures roughly 18mm × 55mm (0.7in × 2.16in). Figure 2-3 and Figure 2-4 show the top view and bottom view of the PCB.

The in-cabin applications require the mounting of the radar device at an appropriate position to efficiently cover the region inside the cabin. Mounting positions like the center overhead mount, front mount, side-pillar mount, second-row overhead mount, and so forth, are explored by manufacturers to achieve the best coverage. This reference design is designed with a form factor to enable the radar to be fixed at the front overhead mount position for two-row coverage as shown in Figure 2-5.
