with the label number model etc...it should have it printed on the sleeve...(eg. RGxx)
-
they INTERACT for the WORSE ! without simulation ...hard to know...
-
UK 's Amateur radio unit (3.5ghz) reverse engineered to 2,4 ...working on it Using teflon as dielectric about 30 by 35 cms It SHOULD be closer to 18dbi... Efficiency still low...(depends on DIELECTRIC and Thickness)
-
metal THICKNESS and DISTANCES...that's all of course SHAPES are of the utmost importance ... every time you PUT a discrete port between two metals on ANY PLACE ...CST would tell you the impedance THERE...
-
That is called POLARIZATION both RX and TX should have the SAME (type of antenna) (linear) Vertical , Horizontal , CIRCULAR RH LH (used a lot on FM , it gets inside moving cars) , ELIPTICAL . you could get 3db more of signal just by moving the antena 90 degrees...
-
discrete ports are the probes i'm talking about...coupling is directly calculated every time you use more than one port
-
20dbi...hard to swallow... 16...17 ...maybe
-
Impedance on any antenna could be tailored to any need...(with some compromises)
-
when you put TWO probes you'll get S11 for the interactions as S12 and S21 in the S-parameters results...
-
BI QUADs for dTV
-
MOST of the times it is at the CENTER of the wire (for all cases) it's a terrific antenna...i used 1.5mm...balun is of the utmost importance. feeding line (parallel horizontal lines) distance TOO or ask the designer is a good guy replies everything ddobricic@gmail.com
-
CST MWS... as it is (5cm to reflector)...is NOT GOOD this gets better at 7 cms CENTERED at 600 mhz the best results impedance as it is is close to 50 ohms (Around) it could be tunned to 75 ohms
-
Impedance , vswr an S11 is wrong...so far Gain is okay at High frecuency
-
the GAP is of most importance for impedance
-
-
strip width...? thickness...?
-
is a pcb antenna ? An all wire or metal sheet (NO DIELECTRICS) would ALWAYS be better...

ACIS .sat sab What year...? or STL iges step NASTRAN...?

TV dish with support 69 cms 69 cm tv dish.cst
-
use THIS one o change material to PEC or any metal offset dish.cst

offset dish.cst

nop...but maybe JOMY have one... diameter F/d ?
-
you could start with my model and tweak it to your needs...CST MWS 2020
-
well i personally ADAPTED 3,5 ghz and 5,8 ghz designs to 2.4 ghz ... any antenna could be UP-scaled or down-scaled... haven't tried slot feed yet...(it seems hard to get it right on DIY) but the PATTERN and PATCHES design could be used on ANY frequency system...(MiMo array) CP There's NOTHING unusual on the design...(except the electronics and the frequencies) feel free to delete
