  • Patent number: 10170833
    Abstract: A transmitter or receiver can include a phased array antenna system in which multiple characteristics of a transmitted or received beam can be controlled electronically. For example, in embodiments that include a transmitter, dual outputs of N signal modifiers can be connected to orthogonal inputs of N dual-orthogonally polarized antenna elements. Each signal modifier can modify the amplitude and phase of a communications signal in two parallel signal paths to produce two signal components each of which is an amplitude-modified/phase-shifted version of the communication signal. Multiple characteristics of the combined beam can be simultaneously controlled by setting the amplitude and/or phase-shift parameter values in the dual signal paths in the signal modifiers to combined values that individually affect each of the multiple characteristics of the combined beam.

  • Patent number: 9634403
    Abstract: Pattern shaping elements shape a radiation pattern generated by one or more antennas. A MIMO antenna system generates an omnidirectional radiation pattern. One or more pattern shaping elements may include metal objects which act as directors or reflectors to shape the radiation pattern. The shaping may be controlled by selectively coupling the pattern shaping elements to a ground plane, thus making them appear transparent to the radiation pattern. The pattern shaping elements may be amorphous, have varying shape, and may be symmetrical or asymmetrical. Different configurations of selected pattern shaping elements may provide different shapes for a radiation pattern.
