NoiseKen - TEM Horn Antenna - EMC Testing in the 5G/IoT Era
The TEM horn antenna is an antenna used for conducting close proximity radiation immunity evaluation test (near electromagnetic field immunity test) of electromagnetic waves radiated from various wireless transmitters such as mobile devices.
In the future, close proximity radiation immunity evaluation test using the TEM horn antenna is expected to expand to various product standards such as medical equipment (IEC 60601-1-2) and multimedia equipment (CISPR 35).NoiseKen's TEM horn antenna has a wide band, low VSWR, and wide electric field uniformity offering an ideal solution for an efficient close proximity radiation immunity test.
- A TEM horn antenna compliant with IEC 61000-4-39 Ed.1.
- Test without changing the antenna in the frequency range of 380MHz to 6GHz.
- Low VSWR and high GAIN enable efficient electromagnetic wave radiation.
- Wide field uniformity reduces the number of times of movement of the antenna when radiating the EUT.
- Since the maximum point of the near electric field distribution for each frequency is at the center, enables radiation on the EUT based on the axis of the antenna. Hence, significantly simplifies test point alignment.

Electric field distribution characteristics
The importance of uniform electric field
Compared to a conditional TEM horn antenna, the wide and uniform electric field that NoiseKen TEM Horn offers allow tests to be conducted with fewer repositioning of the antenna and consequently shorter amount of time.
