What kind of polarization does this microstrip patch antenna have?

i have simulated a microstrip patch antenna here is the result i get. I would like to knw wat kind of polarization is tis antenna has from this plot.

Hi danesh

I think you have linear pol ant. good circular antenna have 0db Axial Ratio
you have high Axial Ratio so its not circular ant.

Hello Danesh,

Visit http://rfry.org/ . This URL contains several papers which will be usefull for you to get better understanding of antenna fundamentals.

By the way figure does't shows it a circular polarozation.

Thanks

You have E_left = E_right, thus the polarization is purely linear
