  • Honeycomb-Vent-high-frequency-1
  • Honeycomb-Vent-high-frequency-2
  • Honeycomb-Vent-high-frequency-3


  • 5G band honeycomb vents are made of aluminum and used as a ventilation panel for EMI shielded room and shielded box.
  • It has superior EMI shielding performance even in 5G frequency band of 60GHz or higher (millimeter wave), and are designed to allow air, heat, and light to pass through.


  • Superior frequency band coverage (<-70 dB @ 100 KHz to 67 GHz)
  • Supports 60GHz or higher for ultra-high frequency band (millimeter wave, 5G frequency band)
  • No need to add additional frames when installing
