A novel broadband horizontally polarized (HP) omnidi- rectional planar antenna is developed for mobile communications. The proposed antenna consists of four printed arc dipoles that form a cir- cular loop for HP omnidirectional radiation. A broadband feeding net- work which includes four broadband baluns and an impedance match- ing circuit is designed to excite the four arc dipoles. An eight-element linear antenna array is developed for 2G/3G base stations. A broad- band power divider is used to feed the antenna array. Experimental results show that the HP omnidirectional antenna element has a band- width of 31% (1.66{2.27GHz) while its array has a bandwidth of 34% (1.67{2.35GHz) and an omnidirectional antenna gain of » 8dBi. Both of the antenna element and its array have good omnidirectivity over the 10-dB return loss bandwidth. Simulated and measured results for the antenna element and its array are presented.
