Abstract
Disclosed is an individual rotating radiating element which causes an electrical phase change with the mechanical rotary motion of a rotating radiating element and an array antenna using the same. The individual rotating radiating element comprises an auxiliary structure formed of a dielectric, a helix element inserted into a spiral groove on a side surface of the auxiliary structure, a ground plate coupled to a lower surface of the auxiliary structure; a driving unit including an opening in which the ground plate is placed and rotating the auxiliary structure, and a spatial electromagnetic coupling structure having a first feed pin and a second feed pin electromagnetically coupled each other during power feeding is inserted through a lower surface spaced apart from the upper surface with an inner space therebetween.
