This paper analyzes a dual-band omni-directional antenna with horizontal polarization.A group of printed dipole antenna is used for omni-directional radiation.Double radiation arm and trapezoidal feed line are used to realize dual-band in 2.4~2.5 GHz and 5.1~5.9 GHz with return loss of generally less than -10 dB.The gain in low frequency is 1.2 dB,and its un-roundness is 0.2 dB.The gain in high frequency is 2.4 dB,and its un-roundness is 2 dB.The antenna has simple structure and good omnidirectivity.

Key words: horizontal polarization;omni-directional antenna;dual band
