【High-Frequency Electromagnetic Wave Absorbing Sheet】 This is a thin sheet that absorbs high-frequency electromagnetic waves. We propose product forms tailored to your needs, including laminated adhesives. This product excels in electromagnetic wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability. It is ideal for countermeasures against TX-RX coupling in modules such as ETC (5.8GHz), X-band (8-12GHz), ship radar (3GHz, 9GHz), proximity radar (24GHz), high-speed wireless transmission (38GHz), high-speed wireless LAN (60GHz), and vehicle-to-vehicle radar (76GHz), as well as for absorbing unwanted radiated noise, addressing misoperation due to ETC multipath reflection, and ghosting issues caused by nearby metal structures in radar applications. 【Electromagnetic Wave Shielding Fabric】 ● Compared to shielding measures using metal, it is lightweight and easy to handle. ● Ventilation holes: High breathability conductive fabric allows for shielding at the hole areas. ● It shields low-frequency magnetic fields, has excellent high-frequency shielding performance, and offers outstanding breathability and flexibility typical of fibers/fabrics. It is lightweight and has excellent processability for sewing and cutting, using polyester threads that do not generate dust.
