parabolic reflectors antenna simulation

[ferdows]

hi
i want to know how i can simulation a parabolic reflectors antenna in HFSS or FEKO ?

hi ferdows if you want simulate parabolic reflector antenna i advice you the moment method namely feko. if your memory is insufficient you can change the solution method on feko. MLFMM or PO (Physical optics)
if you use CST you can simulate with integral equation method
in HFSS maybe required more memory than others
if you use FEKO i can send you the parabolic reflector antenna simulation feko file it will be simulated by me

And the antenna you will design
firstly compose a paraboloid shape it have focus and aperture
f/D must be between 0.6-3 to provide aperture efficiency high
use horn antenna to feed the paraboloid.
the horn phase center and focus of paraboloid should intersect.

But if you want cosecant squared dish antenna you should give effort for compose the 3D geometry of dish

hi
pls send to my email u simulation

hi
pls send to my email u simulation

sure i will send you tomorow, i should sleep now

hi i attached the parabolic reflector antenna modeled in feko bu had not simulated for simulation of parabolic antenna needs about two days so i will send you the simulaton result of parabolic reflector with method of moment after 2 days
3 files are in rar file.
parabolic reflector set up
with method of moment
with pyhsical optics method
and with fast multipol method
you simulate and see difference between these methods..

hi all
i found a power point about reflectors antenna and i attach her

Hello Sir , Could you please email me learn of feko , I desing the antenna in 3d software and now I have put it by igs format in to Feko and simulated , please advise and help , thank you

HI GUYS NEED URGENT HELP PLS.....CAN SM1 SEND ME A SIMULATED REFLECTOR ANTENNA FILE IN FEKO....I HAVE STARTED WITH DIS SOFTWARE N HAVE N URGENT NEED OF A SIMULATION OF REFLECTOR ANTENNA...PLS SEND ME SM LINK OR PLS MAIL ME AT jerrinjohn2010@yahoo.co.in PLS.....:-|

THANKS IN ADVANCE
