Sequential Rotation technique

Dear RF people,

I'm designing a Circularly Polarized patch antena array and I've decided to use the Sequential Rotation technique.

My question is: can I work with a Single Element whose Crosspolarization level is -12 dB at Edge Of Coverage (+/- 13degrees) and lower at the boresight?

If I apply the sequential rotation technique at array level, can I be sure to have an overall array Crosspolarization level less then -20 dB in the all Coverage (-12 ; +12°)?

Every comment is welcome.

Regards,

Lupin

Thanks plasma for your contribution.

I'm going to read the paper.

Anyway, can I know your expert feeling about my question?
