The antenna which provides circularly polarized waves is
Helical antenna
A helical antenna consists of a conducting wire wound into a helix shape, typically over a ground plane. When designed and operated in a specific mode (axial or beam mode), the helical antenna is known for radiating circularly polarized waves.
