Abstract
The invention is applied to transmitting indoor signals and provides an indoor omnidirectional antenna. The omnidirectional antenna comprises a vertical polarized antenna which is axially provided with a horizontally-polarized antenna, wherein a baffle wall is arranged between the horizontally-polarized antenna and the vertical polarized antenna. The baffle wall promotes the non-relevance (i.e. isolation degree) between the horizontally-polarized antenna and the vertical polarized antenna of the indoor omnidirectional antenna and meets the demand of the LTE system on double polarizing the indoor omnidirectional antenna. The horizontally-polarized antenna and the vertical polarized antenna meet the technical demand of MIMO (Multiple-Input Multiple-Out-put).
