current distribution path in hfss for patch antenna

[KUHELI]

Hy all... I m working in HFSS for designing patch antenna... I have plotted current distribution path by using vector_jsurf. But the plot has 3 to 4 arrows.... from the plot it is not clear how the current is flowing in the patch. The plot has only 3 to 4 arrows across the edge of the width of the patch. but there is no arrow in the feedline or in the middle of the antenna.
i am confused wheather i m following the correct instruction or not . if i am following correct instruction, then what can be the reason of not getting lots of arrows in the patch.
Please, help me.. Your reply will mean a lot to me...

you can increase the no of arrows by using the modify the plot attributes.
