,, yes, I know it... long ago...!!!
,,, this antenna is very complicated to execute on the PCB and for so many patches, the gain is very small..!!!!
The patches should have a simpler geometry...!!!

,,, this variant in the air, is more interesting but with simpler patches...!!!

I know , you hate DIELECTRICS!

 

 JOMY ,Thought , yo could give it a GO at the simulation , i get 18.8 dbi , low , very low EFFICIENCY

,,,Clanon, air antenna, other dimensions are required...!!!

[clanon 246]

YUP...EVERYTHING changes...changing substrates....have you worked with STYROFOAM ? (polystirene foam) if so...what constant and tangent loss should i use...some say 1.11 dielectric and some 0.003 loss...LOW DENSITY foam...

[Admin 2545]

I use the dielectric constant = 1.2

[clanon 246]

Efficiency is low...i blame the FR4 ... so far...(not sure though)

,,, clanon, you, can post its technical drawing...???

I am most interested in the transmission lines .. !!!

the cst file is there   https://www.wifi-antennas.com/applications/core/interface/file/attachment.php?id=7802

...what you need dxf...dwg...?

,,,no,I want just a drawing...!!!

[clanon 246]

It's a MIRROR symmetry in the VERTICAL AXIS...

,,,no,something like this...

[clanon 246]

[clanon 246]

i dont' undestand this part ...; 

9mm desde reflector to cara de cobre PCB

6 mm entre reflector y placa cobre no cara de cobre.

 

must be 6mm to square...?

,,, okay, if you put in place of rectangular patches, elliptical patches, like, what do you say ... ???

[clanon 246]

DROP like could be nice...

[Admin 2545]

[clanon 246]

notice 8 internal patchs at HIGHER frecuency than 8 external patchs...two paks of resonance...it seems..

PS: the SCREWS are very IMPORTANT! there
