DISTANCE and AREA/SHAPE (curved angled) is IMPORTANT ...fiddle with it use a fast and sensible indicator of level quality
-
Transformed from dwg , 9mm to reflector , 1.5mm FR4. ant24-1800.cst
-
I start up with PEC and NO loss materials...then ...when you get close to your goal , you could switch'em to REAL WORLD materials... PS: The ENCLOSURE has a MAIN ROLE in FR , and losses...imho
-
if you don't get closser to -60dbm or even under -60... AND link QUALITY (PACKETS) OVER or CLOSE to 70% you won't have SPEED or stability If you can , try a reflector (ANY METAL) behind your antenna and the signal direction...

Port 2 is not getting to 20...i'm working on it...TOO MANY stubs and LONG feed lines... Is the one on the left

-
What ya think...? JOMY Port 1 (middle port)
-
LOTS of STRIPLINE HAIRPIN FILTERS...

video link...? or antenna name model...?

Port 2 working nice...Port 1 NOT so much...
-
almost SAME SIZE or evevn SMALLER than Directors...
-
Nop.
-
i'm guessing Patches at 2500 Mhz and directors at 2700 Mhz... what you think...?
-
-
They are squares ; 5 by 5 cm (more or less) Directors are roof isolation Polyurethane (almost same length) starting to draw right now... feed lines are complex for MIMO... we'll see
-
well...the best "amplifier" is a GOOD (optimal) antenna , matched to RADIO specs... Sensibility is MOST important (for client anyway) "reception signal" PS: so what are your requirements... Distance , Mimo (speed), modem specs...bands used...

or ...

(Its supposed to be 2cm) i tried from 5mm or less to 25 mm and more...NOTHING S11 never gets under 7 , 8...or LESS Z goes up to 20 ohms MAX...(never passes 15 , 20 ohms) tried 1mm and 0.5 FR4 , Rexolite and Roger...(Nothing) What i DIDN't try was a DIFFERENT PORT...(only discrete)
