Complex elements for antenna of radio frequency repeater and dipole array circular polarization antenna using the same

A dipole array circular polarization antenna in which a plurality of complex elements for an antenna of a radio frequency (RF) repeater are disposed on a bottom surface of a reflective patch element that absorbs and intercepts electronic waves and is formed in a form of a box shape having an opened upper portion, by a predetermined distance, wherein the complex elements comprise:

• a plurality of radiation members which are separated from one another by a predetermined angular distance and comprises a radiation portion and a leg portion, the radiation portion comprising a pair of parallel portions, which are separated from each other in a vertical direction and are disposed to be parallel to each other, and a connection portion, which is disposed to be perpendicular to the pair of parallel portions and connects ends of each of the pair of parallel portions, and the leg portion extending from the radiation portion;
• and
• a plurality of feeding members, each of the feeding members connected to each of the radiation members that face each other, among the plurality of radiation members.
