A novel near‐field shielding measurement method is presented for small shield cans used in modern mobile devices with metallic cases. To effectively capture electromagnetic leakage through the shield cans at the very near‐field region, a stripline mounted on a test board is utilised similar to the integrated circuit stripline method. Using simulation and measurement, it is verified that the proposed method is more accurate and effective than the conventional gigahertz transverse electromagnetic (GTEM) cell measurement method for shielding evaluation of small shield cans used in metallic mobile devices from an radio‐frequency interference point of view.
