An omni-directional antenna module includes a plurality of vertically and horizontally polarized antenna elements arranged to provide 360&#xb0; 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.

Vertically and horizontally polarized omnidirectional antennas and related methods

An apparatus, e.g. a hybrid antenna, includes a plurality of antenna arrays. Each array includes antenna elements, and each array is located on a polygonal antenna body such that each array faces a different direction. An RF network includes first and second duplexers and a divider. The first duplexer is configured to split a received multifrequency drive signal into a first component having a first frequency and a second component having a second frequency. The divider is configured to split the first component into attenuated portions, and to direct one of the attenuated portions to a first of the plurality of antenna arrays. The second duplexer is configured to combine another of the attenuated portions with the second drive signal component to form a combined drive signal component, and to direct the combined drive signal component to a second of the antenna arrays.

Combined omnidirectional and directional antennas

An antenna array may include a plurality of co-planar antenna elements forming a sub-array, and at least one non-planar antenna element configured to tilt relative to a planar orientation of the sub-array to provide an air-to-ground service.
