Abstract :
Impact of the cross-polarization of a large circularly polarized (CP) square scanning array arising from the cross polarization performance of a CP microstrip antenna element is investigated. Techniques and limitations of rotational layout and sequential phase feeds for cross-polarization reductions are presented for uniformly aligned and staggered square arrays.
