Abstract
A broadband dual-polarized omni-directional antenna and a feeding method using the same are provided. By setting a vertically polarized antenna and a horizontally polarized antenna each in co-axial, the horizontally polarized antenna is attached to an upper surface and a lower surface of the attaching plate respectively by two arms of a folded dipole and the two arms connect to an inner conductor and an outer conductor of a feed line so that the dual-polarized antenna may have a comparatively broad bandwidth. At the same time, since the dual-polarized ceiling antenna has a good isolation effect and coverage balance, it may work as the MIMO antenna in the LTE and WLAN systems effectively and may be used in the 2G and 3G networks to improve the data transmission rate.
