In this paper, a new printed dipole array omnidirectional antenna is proposed. Its bandwidth is enhanced by using symmetrical and two-section impedance matching feed circuit. The simulated and experimental impedance bandwidth with VSWR <; 2 are around 19% or from 668MHz to 808MHz. The gain is large than 6dBi within the bandwidth. The fluctuation in H-plane radiation pattern is less than 3dB.
