## Abstract A 2โ€turn helical antenna with small pitch angle between 0.6ยฐ and 3ยฐ has been studied as a radiation element of circular polarization waves in this article. The antenna with pitch angle 2ยฐ exhibits a 3โ€dB axial ratio bandwidth of 9.8%, and the optimal axial ratio of 0.1 dB. When the pitc
