【High-Frequency Electromagnetic Wave Absorbing Sheet】 This is a thin sheet that absorbs high-frequency electromagnetic waves. We propose product forms tailored to needs, including layers of 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 interferences 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 metallic structures in radar applications. 【Electromagnetic Wave Shielding Fabric】 ● Compared to shielding measures using metal, it is lightweight and easy to handle. ● Ventilation holes: By using highly breathable conductive fabric, shielding at the hole areas is possible. ● It shields low-frequency magnetic fields and has excellent high-frequency shielding performance, with 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.

Electromagnetic wave shielding fabric

A lightweight new material that shields electromagnetic waves from 100KHz to 5GHz and excels in processability such as sewing and cutting. *Flame retardant mark obtained.

● It excels in electromagnetic wave shielding (reflection, absorption, blocking, and shielding), and since it is a conductive fabric, there is no generation of static electricity, allowing the entire fabric to be grounded. ● Weight reduction: Compared to shielding measures using metal, it is lightweight and has good handling properties. Ventilation holes: By using highly breathable conductive fabric, shielding in the hole areas is possible. ● The fabric is made of aramid fibers coated with copper and nickel plating, providing high conductivity, bend resistance, and flexibility. Additionally, aramid fibers are high-performance fibers that possess both heat resistance and flame retardancy, and are used in items such as firefighting suits. ● The three-layer structure of PET yarn plated with Ni (nickel) + Cu (copper) + Ni (nickel) exhibits excellent shielding properties.

ノイズ抑制シート.jpg

Radio wave absorption sheet, electromagnetic wave absorption sheet, high-frequency countermeasure sheet, noise suppression.

The thin sheet that absorbs high-frequency electromagnetic waves excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability.

In recent years, the number of electronic devices and radar emitters that emit high-frequency waves has increased, and correspondingly, EMC and EMS measures have become essential. The "high-frequency compatible electromagnetic wave absorption sheet" absorbs electromagnetic waves in the gigahertz range of 5 to 110 GHz. It can be customized in terms of materials, mixing ratios, and film thickness for the electromagnetic wave absorption layer and metal reflection layer to match the frequencies emitted by electronic devices. As the speed of CPUs and other components increases, the noise frequency range is shifting to high frequencies, making it difficult for traditional ferrites and filters to prevent interference with signal waveforms, complicating noise countermeasures. This product excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability. It is suitable for countermeasures against module TX-RX crosstalk (ETC at 5.8 GHz, X-band at 8-12 GHz, ship radar at 3 GHz and 9 GHz, proximity radar at 24 GHz, local 5G at 28 GHz, high-speed wireless LAN at 60 GHz, vehicle-to-vehicle radar at 76.5 GHz, and millimeter-wave noise countermeasures from 50 GHz to 110 GHz), ground plate crosstalk countermeasures, unwanted radiation noise absorption, communication facility sites, countermeasures against ETC misoperation due to reflection, and ghosting issues caused by nearby metal structures in radar applications.
