trianngle rt5880.cst
- Today
-
I think it's easier to post the CST file....!!!
-
, im using roggers RT5880 with thickness 0.787 mm and copper thickness is 0.035 mm and feeding location is x = -1.5 and y = 3.
-
is power point means feeding point??
-
,,,but you need to show the positioning of the power point and the thickness of the PCB...!!!

hi , i have attached the picture with diamensions , yes from cst studio,sorrry unfortunately wrote with caps lock , next time i will write in normal letter.
-
,,,hi buddy...!!! welcome to this forum...!!! if you can give some dimensions it would be better! Gerber files are from CST-Studio...??? And why don't you write in normal letters?

HELLO ALL , IM NEW TO ANTENNA DESIGN . IM DESIGNING A TRIANGLE ANTENNA WITH TRIANGLE GROUND AND PATCH WITH COAXIAL FEEDING ( HOLE FEEDING). MY QESTION IS I HAVE CONSTUCTED THE CONNECTOR BY WACHING SOME TUTORIALS AND NOW CAN I USE THIS THE NORMAL 50 OHM CONNECTOR WHICH IS AVAILBALE IN THE MARKET AFTER FABRICATION. AND HOW CAN I GENERATE THE GERBER FILES FOR THE FABRICATION . AND THE RESULTS I HAE ACHIVED IS 5.991 GHZ @ S11= -32.31 DB AND VSWR IS 1.049 AND GAIN OF 6.3DBI. IS THIS RESULTS ARE GOOD OR DO I NEED TO CHANGE ANYTHING? HOPE I GET THE SOLUTION THANKS.

722 v2 CHICO! a 200 metros con cualquier cosa de mas de 15dbi debería conectar y mantener señal Puedes soldar directo a la usb (cable lo mas corto posible)y desde allí cable usb hasta 4-5 metros From 200 meters anything above 15dbi should do it , Can you solder the USB card closer to the antenna and then a longer USB cable (no loss) 75ohm catv cable no no

I built this Wi-Fi antenna using the 8-disc model from the Aerial website. It works well, but I have a lot of signal loss mainly because I live in a building (on the fifth floor) and the ocean is in front of me. I have no choice but to point it sideways (through my bedroom window) toward an area where there are only more apartments that block the signal. I just wanted to post this here and get your opinions. My goal is to connect to the Wi-Fi network of a hotel that is to the right of my building, about 200 meters away. I have connected before, but at times the speed drops to 0 kb and then goes back up. I'm using a TP-Link 227N v2 Wi-Fi adapter (I think that's what it is). I'm attaching a photo of how I made the "connection." I plan to build an antenna with more directors in the near future... Greetings from Cuba.

The antenna is fed by a dipole at the midpoint between the two reflectors and yields useful gains of 10-15 db.
-
Yes only one view I have tried smaller antenna with high dk still no help because gap is still I need to maintain Vertical

11 degrees is Elevation (UP and Down) not Width (Azimuth) on this...and you aren't specifying the Polarization (is it Vertical...?)
-
Higher the Dielectric constant...the smaller the antenna ...and BIGGER the LOSSES...(unless is Teflon sheet) or Foam...
-
Maybe this suits you...!!!
-
I want same performance in 350mm max lengths. That's where I am trying
-
The one you posted should be closer to 15 degrees Elevation lobe , AZIMUTH...closer to 120...you should check the 2d Plot
-
-
What does "11 degrees" mean to you?, is it somehow angular width? ,,,,anyway, you can choose from here...
-
Yes, but want beam width 11deg in small size around 400mm max length and width100mm
