High-gain, omni-directional antenna systems for MIMO technologies

A device, comprising:

• a radome housing;
• and
• an antenna system located within the radome housing, the antenna system comprising:
• two arrays of horizontally polarized radiating elements and two arrays of vertically polarized radiating elements, each array having a roughly 180-degree radiation pattern, disposed about a central axis in a common horizontal plane, arrays of common polarization separated by 180 degrees, the horizontally polarized radiating elements comprising a plurality of slot elements and the vertically polarized radiating elements comprising a plurality of dipole elements, each of the two arrays of horizontally polarized radiating elements and each of the two arrays of vertically polarized radiating elements arrays being fed using a corporate feed;
• and
• at least one printed circuit board, the plurality of slot elements and the plurality of dipole elements being disposed on the at least one printed circuit board, the at least one printed circuit board including the corporate feed that is fabricated onto the at least one printed circuit board.
