I am designing a stacked patch antenna.After simulation, I can see the E field overlay,but the vector J_surf has only an arrow from the feed point.
In the other part of the patch, the current seems to be zero.
Can anyone help me with this problem?
Re: why can't see the current distribution of antenna using
I guess you need to scale it. right click on the legend of the figure (vec J_surf) and go to scale, marker/arrow tab. Play around with different scaling.
If that does not work and you still cannot see the J over the patch, please upload your file. we can take a look at the design.
