This paper proposes a new broadband horizontally polarized (HP) omnidirectional antenna for wireless communications. The proposed antenna includes four printed arc dipoles and a broadband feeding network. The four arc dipoles fromed an loop for horizontally polarization in omnidirection. The feeding network consists of four broadband balun and an impedance matching circuit. The simulation shows that this antenna has a bandwidth of 31﹪(1.66 GHz-2.27 GHz) for return loss≥10 dB. The omnidirectivity is less than 1.5 dB over the whole frequency band. In addition, an e-element omnidirectional horizontal polarized antenna array is designed. Measurement shows the array has a bandwidth of 34%(1.67-2.35 GHz) for return loss≥10 dB. The omnidirectivity is less than 2 dB over the whole frequency band for the antenna array.
