Hi all,
I am simulating microstrip antenna using CST software, I want to know the polarization of the antenna , if linear (Horizontal or vertical) , or circular polarization, I got some axial ratio result but I could n`t understand it, Any one can help me please, how can i know the polarization state from Axial ratio figure or if its possible to get it directly from CST?
 

High axial ratio means linear polarization, low axial ratio means circular, but you can not tell which one is it (horizontal or vertical, RHCP or LHCP). HFSS can plot all these automatically, most probably also CST, just find it out.
