11.1 Layout Guidelines

Reflections and matching are closely related to loop antenna theory, but different enough to warrant their own discussion. When a PCB trace turns a corner at a 90° angle, a reflection can occur. This is primarily due to the change of width of the trace. At the apex of the turn, the trace width is increased to 1.414 times its width. This upsets the transmission line characteristics, especially the distributed capacitance and self–inductance of the trace — resulting in the reflection.

NOTE

Not all PCB traces can be straight, and so they will have to turn corners. Figure 13 shows progressively better techniques of rounding corners. Only the last example maintains constant trace width and minimizes reflections.
