Abstract
This invention discloses a multi-mode antenna and a base station, the multi-mode antenna comprising a CDMA dual-polarized antenna for CDMA radio frequency signals and two MIMO dual-polarized antennas for LTE radio frequency signals with a plurality of linearly arranged radiation elements; the two MIMO dual-polarized antennas are respectfully vertically stacked right above and right below the center radiation element of the CDMA dual-polarized antenna; and the radiation elements in the two MIMO dual-polarized antennas are nested in or inserted between the radiation elements of the CDMA dual-polarized antenna according to the distance between the radiation elements of the CDMA dual-polarized antenna and the distance between the radiation elements of each MIMO dual-polarized antenna. The present invention combines the technologies of nested antenna radiation elements and vertical isolation separation of MIMO antennas so as to integrate a CDMA dual-polarized antenna and two MIMO dual-polarized antennas into one physical antenna.
