RF Products Broadband Sleeve Antenna MODEL : NKU07M32G/NKU2460G/NKU5080G
Broadband sleeve antenna has been developed for efficient immunity testing against hand-held transmitters and cellular phones. In the conventional strong electromagnetic field immunity test in the near field, it was necessary to replace the antenna according to each frequency, which required a lot of labor and time. These Broadband sleeve antennas is a single antenna solution eliminating the need for antenna changes and dramatically reducing the test time. Furthermore, these antennas with their smallsize and lightweight properties and a flexible handle are suitable for testing in narrow spaces.

- Tests can also be conducted for the 6GHz band (5.925GHz to 7.125GHz) expanded by Wi-Fi 6E and 7.
- A wide frequency range eliminating the need for antenna changes.
- With a power handling capacity of 20W (10W for NKU2460G/NKU5080G), it is capable of testing strong electromagnetic fields.
- High efficiency due to a low VSWR and high gain.
- Suitable for broadband digital modulation thanks to a good VSWR flatness.
- Small, light-weight and flat antennas easy to use in narrow spaces.
- The flexible antenna handle makes it easy to handle and maneuver during testing.
- Since there is little variation in the near-field distribution for each frequency, it is possible to radiate an electromagnetic field to the EUT without changing the position of the antenna.

Calibration services are available for VSWR, electric field distribution and proximity gain characteristics of the Broadband Sleeve Antenna
(NKU07M32G, NKU2460G,NKU5080G). In ISO 11452-9 standard the calibration of electric field is not specified, and testing level is set
in accordance with input power to the transmitting antenna. The calibration allows to confirm proper functions of the transmitting antenna,
which is necessary to ensure the quality of the testing. In addition, the electric field distribution and proximity gain characteristics allow to
confirm the position and strength of strong radiation from the Antenna.■ Image of Electric Field Distribution Characteristics

EMC Testing in the 5G/IoT Era!
The TEM horn antenna is an antenna for conducting a close proximity radiation immunity evaluation test (near electromagnetic field immunity test) of electromagnetic waves radiated from various wireless transmitters such as mobile phones and Wi-Fi equipment.
In the future, the 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.
