Abstract :
In this paper, we have demonstrated the perpendicular dipole antenna with phase shift lines and shown the wideband characteristics of the antenna with phase shift lines in the same direction. The fractional bandwidth of the antenna with phase shift lines in the same direction is 89.5%. Radiation pattern of H-plane becomes almost omni-direction from 5 to 8 GHz.
