  1. Today
  2. Actually no. I do'nt have access to client.
  3. Yesterday
  4. can't you install wifiinfoview or any other software in the client hardware...and look back at the 722...?
  5. Hi I use my tp-link tl-wn722n as an access point. now I need a software to show the signal strength of client which are connected to this AP. does any one have any suggestion? (Please note that I need a software which show client signal strength, not access point signal strength.)
  6. not is NOT the best design for less than 15dbi.... There's hundred or thousand designs for 15dbi or more (in this iste even) EASIER to MAKE With the 722 i use ONLY METAL antennas...dielectrics SUCK the juice of the signals... PS:The BIG change in VSWR is not a real life issue...is a SOFTWARE setting , intersections, port, or other...(can't change THAT much for 0.01 or 0.02)
  7. this is what happen if top and bottom layers miss-match only for 0.4mm
  8. a question about this antenna: I've optimize this design for 1.6mm PCB by increasing Track width for 0.2mm (0.05mm at each size). So by using 1.6mm PCB and this optimization, antenna has a VSWR=1.1 and Re=52ohm at 2450MHz. but my question is: if I increase the track width for 0.4mm (0.2mm at each side), Re will be about 70ohm. it is very sensitive for PCB production. is there a reliable way to manufacture this antenna? I think it is a super sensetive design. if any track width changed or top and bottom layer of PCB miss matched, the antenna loos it performance. is it a good design?
  9. Last week
  10. ,,, another fake antenna made by mcneill...!!!
  11. i'll check and confirm All this for FR4 1mm PCB
  12. ,,, these could be the dimensions .. !!! ???
  13. AHHH! you mean BlueTooth 2400 to 2483.5 (center at 2441.75 and 83.5mhz of bandwidth) YES it's NOT hard once you decide materials and performance...
  14. I mean 10 to 25 MILLIMETRES
  15. yup...you're close 53 degrees ...but it COULD be "tweaked" and "customized"... what you mean for BT frecuency...? Yes it has a NICE 50 ohms curve.... PS: I ussually CENTER to channel 6 (2437ghz) and up and down to ch1 and 11...YMMV When we are satisfied with the results i'll give you the drawings...(dxf , dwg , cst ,etc) or jpgs with dimensions... over the original drawing
  16. Wow, thank you. A couple of questions: Is there a way to visualize the width of the beam in both axis? I'm suspecting that is about 60 degrees Is it tuned for the BT frequency at 50 ohm? If not, how can I do that? How can I manufacture a few of them for testing?
  17. NOP...this dipole arrays (doble sided pcb) ALWAYS have the REFLECTOR FAR AWAY (between 10 and 25 centimeters) PS: I don't think it would change a lot if you peel off the sleeve from reflector to panel...
  18. in this design, reflector is not connected to Ground?
  19. ,,,, why do you want this .. ???
  20. I'll immediately grab your rss feed as I can't in finding your email subscription hyperlink or newsletter service. Do you have any? Please let me understand in order that I may just subscribe. Thanks.
  21. it is better to design Antenna in Professional CAD softwares and then import 3d file to CST. I use CATIA to design 3D files. it is so more easier and faster to create accurate 3d geometry.
  22. for wifi (2,4ghz) ...? (close to 19dbi) it's hard to draw ...with precision...and originally is for 3.5ghz... performance NOT guaranteed...but if you wanna try...
  23. reflector at 20 mm...(needs some refining) FR4 1mm thickness
  24. ok... i'll give it a go this week... and see how it goes...
  25. Sensitivity (how well you LISTEN) and NOT POWER (how much you YELL) is the KEY FACTOR... VSWR (closer to 1 and always under 2.1) is of utmost importance... the TL-WN722 is one of the MOST sensible radios out there (if it has the AR9271 Ver.1.0) I have managed to get connections trough several walls and long distances (with ANY good antenna) the power output...never need more than 100mw...microwaves don't need that much power...because of the high frequencies...(it could be worse with an amp) the 722 (AR9271) should be able to work great with those Yagis... PS: use the SHORTER cable possible and SOLDER direct to antenna...if posible (connectors steal signal)
  26. An other question: for obstacles I use 3wat amplifier. (using a simple 6dbi omni antenna, it can increase signal strength and range for double or triple or more). Can I use these types of amplifiers with above antenna? how can be its effect? Sunhans SH24BTA-N 35dBm 2.4GHz 3W
