Abstract
This document describes techniques and systems for a vertical microstrip-to-waveguide transition. A radar system may include a monolithic microwave integrated circuit (MIMIC) to generate electromagnetic signals and a printed circuit board (PCB) that includes a first surface, a microstrip, and a grounding pattern. The microstrip can be located on the first surface and operatively connect to the MIMIC. The grounding pattern is located on the first surface and made of conductive material. The radar system also includes a transition channel positioned over the grounding pattern, which includes a vertical taper between a bottom surface and a top surface. The transition channel defines a dielectric-filled portion formed by the grounding pattern and its interior surface. The described vertical transition can reduce manufacturing costs and support a wide bandwidth by tolerating an air gap at the transition-to-waveguide interface.
