Millimeter Wave Absorbing Sheet masa sorb series
Ultra-thin millimeter-wave absorbing sheet - wideband, wide-angle, and highly durable
An electromagnetic wave-absorbing sheet developed using sputtering technology. It covers a wide frequency range from 20 to 100 GHz, and despite its thin 0.8 mm profile, it maintains stable performance even in high-temperature environments up to 150°C. It contributes to improved antenna patterns and enhanced detection accuracy in automotive radar applications.

Prevention of malfunction due to noise interference
With millimeter-wave radar increasingly being used in automobiles in recent years, noise interference can reduce the accuracy level of measurements when detecting target distances and angles, such as by reducing the maximum distance at which it recognizes the size of a target.
In addition, interference from other radar antennas can lead to a reduced ability to distinguish between multiple target types.
Thin millimeter wave absorbing sheet for wide bandwidth
Masa-sorb is a thin absorber that utilizes sputtering technology and can be adjusted for specified frequencies (around 20-100 GHz), providing high absorbency over a wide bandwidth.
It is lighter than conventional rubber absorbers and can be easily attached with double-faced tape.
Masa-sorb offers a smoother antenna pattern.
