Radio wave absorption equipment

Low-cost radio wave absorption equipment dedicated to target applications.



System integration

With the spread of IoT (Internet of Things), the development of low-priced and low-cost devices compatible with LPWA such as LoRa and Wi-SUN is progressing, while simulation during wide area communication is becoming an issue. In addition, in measurement methods for high-speed, large-capacity communication such as millimeter waves and 5G standards, adjustment of the positions of the transmitter side (TX) and communication device (RX) is more severely required than in conventional measurements. When verifying each standard, as components other than the shielding effect required at the time of measurement, selection of a radio wave absorber that suppresses radio wave reflection, including the case material of the test piece, and operation of the jig device are major issues. Based on the characteristics of the radio wave absorber selected according to each test standard, our radio wave absorption equipment will consider together with the customer how to use the measurement space efficiently from zero design under limited conditions.

Absorbent for radio wave absorption equipment (Reflection loss ≧-20dB、600㎜×600㎜/sheet)

After investigating the existing equipment in advance, we will proceed with the equipment based on the concrete introduction effect such as the outline design of the radio wave absorption equipment and the arrangement of the radio wave absorption partition after processing. In order to consider the equipment according to your budget, we are preparing the following radio wave absorbers that are different for each frequency.

※Radio wave absorption performance ≧-20dB, each application depends on or includes the lower limit of the applicable frequency.

Jig devices

When considering the measurement space, a device that assists the measurement is required to ensure the reproducibility of the test. In addition to physical differences in size, weight, etc. of the object to be measured, it is necessary to consider how to follow the directivity of the antenna to be measured, the arrangement or movement of cables.

In our radio wave absorption equipment, to meet various needs, we will utilize the know-how of measurement technology cultivated over many years to propose jig devices unique to RF measuring instrument manufacturers.

Antenna Fixing Base

Antenna Fixing Base
Attach the attachment type folder shape to the pedestal of transparent material on the wall panel. It enables flexible measurement according to the target scene, such as changing the plane of polarization and measuring with multiple antennas.


In simple emission tests, communication tests, etc., the directivity of the object to be measured placed on the table is confirmed from different angles.
Especially in a shielded environment, it is effective for cost consideration when darkening a conventional shielded room, such as measuring various antenna patterns.

Electric field strength measuring device

Automatic measurement of radiated electric field strength is performed using an antenna or electric field probe. It is effective for interference wave measurement, proximity immunity test, etc.
