mostly ALL parameters CHANGE when you add a reflector...Z (Real and Reactive), Fr , Gain , etc...(imho) Bat wing antenna "Batwing antennas generate a horizontally polarized signal. " "The "batwing" shape of the elements is used because it gives the antenna a widebandwidth of approximately 20% of operating frequency at a VSWR of 1.1:1"

It's been used from more than a 100 YEARS... But then again the most used antenna is like a quarter wave + balun or half wave alltogether https://martybugs.net/wireless/images/ducky_inside.jpg

...we're EVERYWHERE ...it seems... Aurel do you have DIMENSIONS for that antenna...? 64 mm each wire...i think
-
Multipolarized Yagi...?

Dimensions...? anybody... it wold be nice to adpt it to 2.4ghz...imho

Ceragon REMEC ODU...not shure of "original" frecuency...It's from a Radio Link unit...all i know
-
-
i know...my setting for the solver and or mi discrete port location must be REALLY OFF... (closer to 0 db...i know)
-
-
I wonder if there is a simillar FOOTPRINT SIZE patch with 16dbi or more... Plannar no space for big reflector wings (Haven't found it yet)
-
some little thing is OFF...causing that small side lobe on the right...but the earth ground shape is TOO IMPORTANT to vswr and gain...apparently
-
-
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...
-
Radiation efficiency seems fine... vswr must be the problem...
-
getting there...RE-modeled... i'm gonna work on the coplanar waveguided thingy...now...
-
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

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 - "Foil materials from NELTEC (France) NELTEC is the new name of the company METCLAD. The materials are intended to be used as substrates in microwave devices. The thickness of the dielectric: 0.127, 0.254, 0.508, 0.762, 0.787, 1.270, 1.524, 1.575, 3.175 mm The dielectric constant (at a frequency of 10 GHz): 2.17 ... 3.48 Copper layer thickness: 5, 9, 12, 18, 35, 70, 105 microns Sheet size: 305x457, 406x457, 457x610 mm "

some doubt about INTERSECTIONS...how its supposed to go...
-
-
and then ...discrete port...or what?
-
54 by 46 mm each Patch...i think...
-
-
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 raytron 16dbi.cst

TRYING my best... we'll see...
