  2. Last week
  3. Marketing technik as usual
  4. ...yes, but I don't really trust the gain of the antenna..!!!
  5. Dipole antenna based?
  6. Main technical specifications 1. Frequency Range: 2400MHz 5G 5800mhz 2.VSWR:<= 1,5 3. Gain: 10 dBi (max.) 4. Vertical polarization 5. Maxlmum Input Power: 50W 6. Connector Type: RP-SMA plug/SMA plug 7. Length: 19.5 cm 8. It is widely used for wireless transmitter and wireless receiver. Such as AP, WLAN ,WIFI router, WIFI adapter. 9. Advantage: Nickel-plated has excellent quality in solubility, conductivity and stability in metal. 10. It has two colors, you choose black or white. Thanks.
  7. and I will try to apply it in the real world thank you admin and God who will repay your kindness
  8. Thanks sir
  9. Thank you for your time and everything
  10. ,,,okay, I will try...for the frequency of 1800 MHz...??/
  11. I have 75 ohm material can you give a schematic? let's be clear thanks in advance.. healthy long life for admin
  12. ,,, for the impedance of 75 Ohm, the distance of 7 mm must be modified...!!!
  13. hi admin can this use a 75 ohm cable or do you have to change the distance
  14. I don't really think so, it has to be checked...!!!
  15. Any change for rg316 coaxial cable?
  16. Try to draw a balancing device in the model.
  17. Earlier
  18. The slot dipole with V cut outs like an batwing antenna, not as good for broadband application but a little more compact than the slot dipole and a good gainer. Here an example for a wifi antenna slot antenna with V 24-25.cst
  19. Wow that works like charm, thank you.
  20. If your model is symmetric, you may define this symmetry planes here. For particle tracking calculations the symmetry option can only be applied if no space charge and particle current is monitored. Therefore symmetry conditions cannot be applied for gun-iteration calculations. Important: It is necessary to create the entire structure first. Every symmetry plane you find reduces the calculation time by a factor of 2, so it is always recommended to specify symmetries, if any exist. The type of the symmetry can be either electric or magnetic. f you specify a symmetry plane, the calculation domain is cut in half. The picture on the right shows a calculation domain symmetric to the YZ plane. The symmetry type is electric. The calculation domain is cut in half twice more if a symmetry type for the XZ and XY can be found.
  21. ,,, with other caps, this can also be done... 2.3-2.7 GHz frequency band (UWB)
  22. ,,or a Batwing antenna.... ....with a parasitic circular director....!!!!
  23. ,,,a simple notched lid can be placed in the bucket... ,,,or so with the bottom of the bucket...
  24. You are a real master
  25. ,,,it is still possible...!!! slot patch.cst
  26. then its necessary to analyze the structure and look which parameter is related to lamda and which is perhaps related to other factors. And yes you have to find a center frequency. For a single band antenna this is easy for such a multiband its much trial and error i think. For me its easier to re-optimize the design for another frequency range. For lower frequency's there should be better designs that are not so big, the only other range i can imagine is in the 5GHz region but there you not need such a wide bandwith. Attached you will find the cst file, feel free to recalculate it for another freq. range or to find the lambda depending parameters ;-) slot antenna 17-27-reflectors.cst
