dear all,
m wrking on micromachined microstrip patch antenna array in HFSS. i want to know how to get gain curves E-Plots and H-plots after simulation.
 

Do you want plots of the radiation pattern ?

Basic understanding of E-plane and H-plane radiation pattern. (There's no such as thing as E-plot and H-plot).

Simply E-plane and H-plane are always perpendicular to each other. 90 degrees onto each other.

Thus, to draw E-plane and H-plane.

Set one theta=0, and phi=all angles

or

Set one phi=0, theta = all angles.

You will see your H-plane will have circular and omnidirection patterns. Meaning it's perfect circles.

But E-plane is not uniform.

Remember, this radiation patterns are based on single frequency...so whatever your solution frequency is, that's the radiation pattern for the specific frequency.

This depends on the orientation of the antenna, so that's not a general result which will work in every case. Theta and phi have fixed references to the x, y and z axes. But depening on how you place the antenna, the E and H planes can be anywhere.
