KEYCOM provides solutions in the 300 GHz to 1 μHz frequency range (SHF/EHF/MW/UHF/VHF/ULF).
We undertake designing, manufacturing and measuring. Please feel free to contact us.

Near-Field Antenna Measurement System
We have two types for 110 GHz and 300 GHz.

Model No. ANM01

There are two ways of antenna measurements techniques: in the Near field, within (2d²/λ) of the wavelength λ of the electromagnetic wave, and in the Far field at a greater distance.

This product performs measurement in the Near field and converts it to far field and aperture distribution at any distance.
