Abstract
An omni-directional antenna module includes a plurality of vertically and horizontally polarized antenna elements arranged to provide 360° coverage around an antenna, and to eliminate nulls below the antenna. The antenna elements are arranged in parallel with respective orthogonal axes of a three-dimensional Cartesian coordinate system, with the centers of the antenna elements being arranged collinearly along the vertical or 'Z' axis so that the radiation patterns of the individual orthogonally polarized dipoles do not interfere.
