  • Compliant with ISO 11452-9（2021） and ISO 11451-3（2024).
  • 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.
