hi
can any body plz help me to understand polarization of my antenna,i draw rEx and rEy vs theta then calculate Ey/Ex and converting into db i consider it axial ratio value which is found to be 2 db,similarly i use ERHCP+ELHCP/ERHCP-ELHCP and converting into db i got axial ratio value aproximatly 2db but when i draw axial ratio vs frequency curve AR was higher than 3db and having lower value only at one frequency now can i said my antenna is circular polarized or not?how to find phase between e vectors is 90?also i plot e field vector and it seems to rotate but how can i claimed it is cp not elliptical??????plz who know do help me
