PCB.. ( 31.6 %) ( 19.4 %) 12.2 %. S-,,. Abstract This paper proposed a method of broadband method of dual polarized dipole antenna for 700 MHz band base station. The proposed antenna has a structure that PCB feeder is mounted on the metallic radiator. The design of radiator and feeder is optimized by using 3D EM simulation. The proposed antenna(bandwidth 31.6 %) is broadened over 12.2 % through the lower frequency band than reference antenna(bandwidth 19.4 %), however the size is not increased. Measured results of S-parameters, radiation patterns, and gain have a good agreement with simulation ones.
