Structure resonance can cause radiated emission/immunity issues - how to locate a resonant structure

[@artiomoable]

Thanks for the demonstration. What solutions an fix "trouble" structure at required frequency? Thank you!

[@Schauche]

like your artical and video! very helpful. thank u so much!

Hi Yanjie, many thanks for the great support, it means a lot. All the very best. Min

@@MachOneDesignEMC I wish u a happy new year!🎆

[@MJ-vt1kp]

Great video, did use also couplers for CM or DM current separation? Could you propose any

[@MachOneDesignEMC]

Hi there are methods of doing that, check kzbin.info/www/bejne/ZqamiaZsZZeSbK8

[@KeithRisebroughUK]

Great Video. Thanks for posting. Would you be able to advise the part number of the Directional Coupler from mini circuits ?

[@MachOneDesignEMC]

Hi Keith, sure. Most people use ZFDC-20-5+, but I used ZFDC-10-5+ in the experiment.

[@hwansupark8955]

Could this technique be effective in troubleshooting emissions within the 5 GHz WiFi frequency range, for example, above 5 GHz?

[@chris_lynch]

Thanks for the video, I'll order one of the ZFDC directional couplers to experiment with. One question though, I thought most bank cards NFC/RFID operate at 13.56MHz?

[@MachOneDesignEMC]

i am not sure. will need to check. you might be right!

[@Dev_Nishabd]

Sir what is the software u r using. Did it was connected with any hardware?

[@MachOneDesignEMC]

Hi, that software controls the signal generator I used, which is from Windfreak Technologies. Hope it helps

May the reason for low resonance at 250MHz be due to the inefficiency of loop antennas at 250 MHZ?
