Abstract: An example computing device includes a printed circuit board comprising: a first layer including one or more ground signal paths; a second layer including one or more ground signal paths; a third layer disposed between the first layer and the second layer; a radar antenna portion comprising a first radar antenna and electrically connected to a distal connector of the printed circuit board; a radar clock signal line configured to convey a radar clock signal between the radar antenna portion and the distal connector; and a first ground guard trace electrically coupled to the one or more ground signal paths and positioned adjacent to a first side of the radar clock signal line and parallel to a length of the radar clock signal line.
