1. have omnidirectional'"'"'s multi-input/output antenna of polarization diversity, described antenna comprises:

  • The array of at least one radiator antenna element, described radiator antenna element has level of linearity and polarizes and be configured to carry out omnidirectional radiation according to orientation;

    The radiator antenna element that at least one and described array spacings are opened, this radiator antenna element has linear vertical polarization and is configured to carry out omnidirectional radiation according to orientation;

    Conductive plate, this conductive plate can operate into by described radiator antenna element electrical ground;

    WithRadome, this radome is attached to described conductive plate, thus is enclosed in by described radiator antenna element between described radome and described conductive plate in the collaborative inner space limited,Wherein, described antenna comprises first, second and the 3rd port, each port in described first, second, and third port and corresponding electric connector in line and described first, second, and third port be configured to be plugged to described electric connector.Wherein, described conductive plate is a conductive plate;

    Wherein, the array of at least one radiator antenna element described and at least one radiator antenna element described are arranged on a described conductive plate, make;

    Between the array and at least one radiator antenna element described of at least one radiator antenna element described, Existential Space is separated;

    The array of at least one radiator antenna element described not with at least one radiator antenna element colocated described;

    AndDescribed antenna Existential Space diversity;

    Described antenna can operate into thus;

    For at least one port produce omnidirectional, perpendicular polarization cover;

    AndFor at least one other port produce omnidirectional, horizontal polarization cover.
