From microstrip line corners to board material selection, from impedance matching to grounding, every detail can affect performance. This article uses practical examples to illustrate how to avoid common mistakes, including lessons learned from right-angle routing in 2.4GHz modules, the reasonable application of FR4 materials, and considerations for copper foil roughness in millimeter-wave designs. Practical insights suitable for electronics engineers and RF enthusiasts.
