[noor_awad]

hi :
i'm designing an UWB antena using HFSS v.11
and i want to draw the current distribution on th epatch
i choose field---> then J---> magJ
and i choose the frequency of interset
the HFSS doen't give me that plot
and the icon on the left side is black
could anyone plaese tell me how i can solve that ???

Did you simulate your antenna ?? If not simulate, it should give you results. For plotting the fields you should first select the patch (or all the objects on which you need to plot the fields)then simply right click on the patch choose plot fields---> then J---> magJ. Leave rest as it is, it wil automatically consider your solution frequency and plot your results..

thank you sir for your reply
i did all what you said
the HFSS give me a plot at the "center frequency only"
but when i changed to sweep to select a desired frequency it doesn't give me any color for the current distribution
it just black
