Electromagnetic wave emission pattern measurement system

We provide inexpensive electromagnetic wave emission pattern measurement system which space-saving and installation work not necessary.

Application

By using this measurement system, it is possible to measure electromagnetic wave emission patterns of small radio, antennas, etc. The electromagnetic anechoic box has a radio wave absorber in all six sides. By blocking unnecessary electromagnetic waves and interference waves from the outside and suppresses the reflection of electromagnetic waves radiated from the EUT inside, it is possible to obtain a stable measuring environment with a wide dynamic range.
Moreover, by installing a broadband linearly polarized antenna, it is possible to switch between horizontal and vertical polarized waves by the polarization switching handle on the side of electromagnetic anechoic box .
In addition, use “the automated measurement software”, radiation (directivity) pattern measurement can be performed conveniently. We will evaluate and verify differences in characteristics of wireless devices, antennas, etc. and strive to improve communication technology in the diversifying wireless markets.
