  1. Past hour
  2. What, is it hard to cut a sheet of wire ... ???
  3. Today
  4. how about potential line replaced with 1.5mm copper wire..??
  5. (DTA) is one of the best zig-zag antenna. Her canvas in contrast to the previously discussed antenna differs in that instead of two rhombuses consists of two triangular frames. The antenna pattern in the horizontal plane with no reflector is an eight The input impedance of the antenna in the receive frequency range depends on the antenna dimensions and its forms, from the placement of terminals to which is connected a coaxial cable or other transmission train, and also the location in close proximity to antennas of different construction which influence the distribution of electromagnetic field in space. In this case, the antenna is in good agreement with the coaxial cable is 75-Ohm characteristic impedance without other adaptation
  6. Yesterday
  7. ,,,and the required dimensions...
  8. ,,,,good, and yet it seems to be broadband...!!!
  9. Oh... as we want details......
  10. is it possible?
  11. thanks for correction and yes it work, this patch more signal strength than my omni antenna 10db..
  12. Earlier
  13. ,,, you can not, how as crossing the adaptation line, the potential null point ... ??? !!! ,,,or something of that kind...
  14. I thought the length of the director and vibrator were the same, meaning the director was longer than the vibrator right? thanks brother.. another question .. what about models like this, for the 2400mhz sectoral antenna, is it possible?
  15. " be careful ... vibrator size = 53mmx56mm directory size = 48mmx60mm
  16. the length of the director and vibrator is 56mm, while the nut distance from the long side is 30mm, so the nut is not in the center ?? that's what I meant I tried using a comparison of tplink wr-741nd with default omni and this antenna, the result is still better using omni
  17. ,,,these are the dimensions ... !!!
  18. i thinking if measurement 30mm from director and vibrator not from reflector and i use reflector size is 80x100mm
  19. ,,,good, I do not think this problem influences too much....!!! ,,,what displacement has the nut...???

  20. Simulation of antenna in CST Microwave

    Admin replied to Admin's topic in Modeling antennas

    How to Download & Install CST Microwave Studio-2018....
  21. my mistake have look at the picture, nut not to the center vibrator and director
  22. I think the thickness of the material is not that critical. I used galvanized steel with thickness 0.2 mm for the vibrator and the Director, reflector in galvanized steel with thickness of 0.5 mm.
  23. what material do you use and how thick
  24. I have this design works well. Does the SMA connector match the connector on the router? If so, I don't know what can be changed.
  25. Our Bejonet user says ... ""hi friend, i was made it, but still not good, unlucky me i dont have any instrument for check if this antenna is working or not, just try to connected to my router and wifi signal is not good.."" "and still I do not understand what the problem is ... !!! ???
  26. ,,,okay my friend, but not today...!!!
  27. Buddy... want details, if not difficult ?
  28. Another way to connect the SMA port...

  29. 1800MHz Patch Antenna

    Admin replied to Admin's topic in Modeling antennas

    I thought it would be appropriate to simulate a different antenna on this frequency...
