Radio Wave Absorber "E&C CV"

Radio Wave Absorber "E&C CV"

Broadband, high-performance microwave wave absorber

E&C CV is a high-quality broadband microwave absorber. It is made of a moderately flexible polyurethane foam substrate, and the surface has a helical shape (similar to an egg carton). There are three types available with different thicknesses and lower limit frequencies. The surface is rounded and lacks sharp edges or points, making it particularly suitable for applications in the millimeter wave band and at wide oblique incidence angles. There is no performance degradation up to an incidence angle of 60°. 【Specifications】 ○ Frequency range: 2GHz to 18GHz ○ Absorption characteristics: up to -40dB For more details, please contact us or download the catalog.

[Radio Wave Detection] Battery-powered UHF Band RFID Dedicated Radio Wave Detection Card

[Radio Wave Detection] Battery-powered UHF Band RFID Dedicated Radio Wave Detection Card

Catch the signal! Introducing the "Battery-Powered UHF Band RFID Dedicated Signal Detection Card" with significantly improved sensitivity!

"RFID" is a wireless automatic identification technology that uses IC tags and IC cards. It allows for the writing, reading (recognition), and updating of ID numbers and related information via wireless communication with the IC chips embedded in IC tags and IC cards. Our UHF band RFID dedicated detection card is equipped with a battery! Furthermore, the sensitivity of the radio wave detection card has been significantly improved. Additionally, the strength is displayed in seven levels using seven LEDs. In the case of 4WEIRP, it can detect radio waves even at a distance of 10 meters, and the LEDs will light up. 【Features】 ■ Equipped with a battery to significantly enhance the sensitivity of the radio wave detection card ■ Displays the strength of radio waves in seven levels based on the number of lit LEDs ■ Visually confirms the distribution of radio wave strength, reflection, absorption, attenuation, and diffraction, allowing for a more accurate understanding of radio wave behavior ■ Battery equipped ■ Enables more accurate confirmation of the behavior of invisible radio waves *For more details, please refer to the PDF document or feel free to contact us.

Wave+X Electromagnetic Wave Absorber

Wave+X Electromagnetic Wave Absorber

A radio wave absorber crystallized with new principles and technologies.

"Wave+X" is a radio wave absorber that can eliminate unnecessary radio waves as a traffic controller for radio waves, in order to establish a good communication environment. It plays a central role in the Advanced Traffic Management System (ITS) and has a proven track record of being implemented in the ETC system. Furthermore, it is expected to have a wide range of applications in the future, including gas stations, toll payments, convenience stores, drive-thru toll payments, and vehicle-to-infrastructure information distribution. Additionally, compared to conventional radio wave absorption sheets and panels, it is thin yet demonstrates absorption performance exceeding that of vertical incidence at various angles, starting from high incidence angles of over 40 degrees. 【Features】 ■ Establishes a communication environment ■ Eliminates unnecessary radio waves ■ Thin design ■ Exhibits absorption performance exceeding vertical incidence *For more details, please contact us or download the catalog.

Electromagnetic wave absorbers selectable by application.

Electromagnetic wave absorbers selectable by application.

Ideal for when you want to accurately measure radio waves and suppress radio wave reflections! For experimental equipment and radio wave anechoic chambers.

A radio wave absorber is, as the name suggests, a material that has the function of absorbing radio waves. It converts radio waves into heat and has the ability to suppress reflection and transmission of radio waves. It is used when accurate measurement of radio waves is required or when reflection of radio waves needs to be minimized. 【Applications】 ■ Used on the ceiling, walls, and floor of an anechoic chamber (a room for accurately measuring radio waves) ■ Used in antenna components (improving the directionality of parabolic antennas and weather radar) ■ Used in various experimental facilities. * A comprehensive product catalog is currently available. For more details, please contact us or download the PDF to view it.
