Raytron 16dbi patch

Raytron 16dbi & 19dbi mod

 

Hi , guys it would be nice if some generous soul simulate this one...

The original is 6 elements over 0.787 ptfe , 2.1 dielectric constant...

Clanon, you're from Argentina and you speak Russian...???
,,, please write in English ... !!!

OK , "dude" ...already built it on a notebook ABS cover...with aluminum foil...CST simulation would be great to fine tunning it...

PD: I'm NOT getting 16dbi and a lot of VSWR

[clanon 246]

ABS should be like 2.8 of dielectric constant and 1.5 mm width ...try to keep 5mm to aluminum reflector inside , but it's tricky...not a lot of space

some wifi cards don't like it so it must be high VSWR...channels  from 1 to 11 all show up...poor signal though...

,,,well, the reflector where is ... ???

[clanon 246]

inside 

bigger than patchs and close to 4mm or so the screws touch it on the current centers of the patch

TRYING my best...

we'll see...

[Admin 2545]

Clanon, you can put the dimensions to it...???

 

[clanon 246]

here's the model...not exact just  taken from that picture...

can't make it dance though...

 

Maybe my settings are wrong for the solver... i tried waveguide and discrete port...TO NO AVAIL

54 by 46 mm each Patch...i think...

,,,try to import a SMA port from this forum...

[clanon 246]

and then ...discrete port...or what?

 

[clanon 246]

[clanon 246]

some doubt about INTERSECTIONS...how its supposed to go...

 

[Admin 2545]

... something like that ... !!!

 

 

Anyway, something is wrong ...

 

 

[clanon 246]

try with teflon ...2.1 dielectric constant...Original material ...close to 0.7...(0.762, 0.787mm)

 

PD: I was gettin LOTS of APs...but too litle signal... less than -62dbm...and a bunch with more than -

It SHOULD have one BIG LOBE...in the CENTER (16dbi) and some smaller ones around...IMHO

“Having carefully examined the cable entry point in the photos of the“ original ”, I came to the conclusion that there is not a“ bare ”microstrip, but something like a“ coplanar waveguide. ”Therefore, I provided for such an“ earthen ”polygon at the input

 

 

[Admin 2545]

..., only in English, please...!!!

[clanon 246]

getting there...RE-modeled...

i'm gonna work on the coplanar waveguided thingy...now...

[clanon 246]

Radiation efficiency seems fine... vswr must be the problem...

[Admin 2545]

[clanon 246]

YUP...it's like they're "Forcing" the wave to make a 90 DEGREES through the FEEDING LINE...IMHO...(it must be important) I'll keep you informed if i have success...to 15 or 16dbis...
