The axial helical antenna is composed of a metal helix with good conductivity, and is usually fed by a coaxial cable. Applied in VHF and UHF frequency bands, the antenna gain is high, the size is relatively small, and the structure is simple. The left-hand or right-hand circular polarization can be obtained by changing the spiral direction.
