Abstract
ABSTRACTA wideband horizontally polarized omnidirectional antenna is proposed for 4G LET indoor base stations. Within the band from 1.71 GHz to 2.69 GHz, the antenna achieves a return loss of greater than 14 dB. The antenna consists of four arc printed dipoles which are arranged on a circumference and fed in phase. By attaching a pair of parasitic elements around each dipole, the bandwidth of the antenna is improved significantly. Moreover, by introducing four pairs of directors, the antenna gain variation in the azimuth plane is reduced to 1 dB in the operating band, and omnidirectional radiation patterns are achieved. The measured results are in good agreement with the simulated results. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2112–2116, 2015
