Abstract: An apparatus, system, and method are disclosed for wireless communications. A planar antenna element is disposed on a surface of a substrate. The planar antenna element comprises an electrically conductive material. The substrate comprises a dielectric material. The planar antenna element may be arranged in a planar antenna array as a feed for a reflector antenna or as an aperture array. The planar antenna element may comprise a slot patch antenna element with a slot in the electrically conductive material of the planar antenna element circumscribing the planar antenna element. The slot exposes the dielectric material of the substrate. A ground plane may be disposed on the surface of the substrate. The ground plane comprises an electrically conductive material. The slot may be disposed between the ground plane and the patch antenna element. The substrate may include electronic components for beam steering, upconversion, downconversion, amplification, or other functions.

Abstract: A method is described for extracting aperiodic components from a time-series wave data set for diagnosis purposes. The method may include collecting time-series wave data within a controlled environment were a plurality of contrasting conditions can be used in collecting the time-series wave data set. Aperiodic components can be extracted from the time-series wave data set and the aperiodic components can then be fitted to the plurality of contrasting conditions of the controlled environment to product regressed aperiodic components from which diagnostic determination can be made.
