The present invention relates to a phase shifter of an antenna. The phase shifter comprises two or more, preferably three coaxial-pair patterns and three phase shifters based on three axes, and each arc-shaped pattern and phase shifter are organically connected to form a phase difference in an antenna. On the other hand, rotation of the phase shifters do not interfere an input side matching circuit. According to the present invention, the phase shifter has advantages of forming a larger phase difference compared with the conventional phase shifter, being optimally used in an antenna apparatus, and being able to more precisely control the phase and power ratio. |
