BatWing antenna 2.4 ghz

[Admin 2530]

,,, yes, the gain is about the same on the whole frequency band...!!!

[Mishka 10]

Looks very competitive to the Bester antenna.

I think I could put one to the test. But I've found that this drawing differs from content of the DXF files you've published later. So which one is correct?

The DXF as my QCAD sees:

,,, yes, that's right. my drawing is the good one...!!!!

I still do not understand which is correct?

or

 

[Admin 2530]

,, my drawing is correct...!!!

 I do not know why the transposition in cad programs does not respect the reality...??/!!!

This is exactly how (like the bottom picture) opens in Compass 3D

,,, the antenna profile must be made on Kompass program..!!!

so in it and open your file

[Admin 2530]

,,, yes, I translated * dxf file from CST to Kompass and it doesn't seem to match..!!

can you share the file from CST?

[Admin 2530]

,, this is the * CST file with conical reflector...

 

new batwig.cst

,,, and some dimensions...

Okay, here it is. But it looks different from your drawing. Simulation screenshots seem match your drawings too.

What am I missing?

covina.dxf

Oops, the ellipse smaller radius is 49 mm, of course. The shape shows it correct, but the drawing dimension is wrong. Please use the updated DXF for reference.

 

covina.dxf

[Admin 2530]

,,, not,,, small radius of the ellipse => 49/2 = 24.5mm and large radius of the ellipse => 95/2 = 47.5mm

             the center of the ellipse = 110mm from the 0y axis

 I thought my picture above was pretty clear...!!

I'm sorry, but this doesn't converge into anything practical :-(

Help needed.

 

[Admin 2530]

,,, yes, you're right, my mistake..!!!

   the center of the ellipse = 110/2=55mm from the 0y axis

[Mishka 10]

Yeah, looks very close to the original image now. Thanks a lot!

CUTE! what about SWR? measured with swr-meter?

[Admin 2530]

,,, this is the comparison

between bester  and batwing antenna...

[devton 27]

This is your batwing made in russia! Wow!

p.s he just a little bit mess with reflector angle

[Admin 2530]

,,,this batwing antenna is my project...!!!

 

[devton 27]

i know

swr on video is just beautiful

[devton 27]

hm...what if you try to model Batwing with 90 degree 2d-corner reflector?? 0_o

corner reflector antenna with Batwing instead of dipole!

0.36...0.4 wavelength from corner top to axis of batwing

batwing plane in plane of corner's bisector

[devton 27]

dude used your Batwing to get 5.8  GHz...can you show simulation for your Btwing on 5.2-6GHz?
