circular patch design

hi there
this paper is the base of the circular polarized circular patch design but very old,

Microstrip polarization techniques

I haven't found an electronic version of it, can anyone help on this?

thanks

Hi,

Check the book, "Microstrip Antennas" by Pozar. It has topics related to polarization.

Thanks
