In this paper wideband dipole antenna that is usable as PCS/WCDMA/WiBro/WiMax public relay station antenna is proposed. The proposed antenna that designed by using double ring structure improves bandwidth performance of existing dipole antenna to wideband performance. To verify wideband performance and isotropic radiation pattern of the proposed antenna, simulation and fabrication have progressed its radiation characteristic has measured and then compared with calculated result. Measured result is similar to calculated result and has gain of 2dB VSWR of 2:1 over 1.75~3GHz. It is considered that the dipole antenna that designed in this paper can be usable as PCS/WCDMA/WiBro/WiMax public relay station antenna.
