RF Shields are physical barriers or devices designed to reduce or eliminate interference from radio frequency signals. They are made of conductive materials (such as metals, alloys or conductive coatings) that effectively isolate, absorb or reflect RF signals, protecting sensitive electronic devices and circuits from external electromagnetic interference (EMI) and radio frequency interference (RFI). The components of RF shielding typically include a conductive housing, a grounding design, and possibly a filtering circuit, which is designed based on electromagnetic shielding theory to achieve effective shielding of RF signals in a specific frequency range by optimizing material selection, structural layout, and grounding strategies. These product characteristics make RF shielding play an important role in ensuring the performance and stability of electronic devices.
