Abstract: In some embodiments, a phased antenna array system includes antenna sub-arrays spaced apart from one another about a mobile device chassis, with each of the antenna sub-arrays including one or more antenna element. One or more of the antenna sub-arrays are selectively addressable to generate an aggregate response among a combination of the plurality of antenna sub-arrays to steer one or more signal beam in a desired direction.

Abstract: Wideband phased mobile antenna array devices, systems, and methods include antenna elements arranged in a substantially linear array and positioned and adjusted on a substrate to achieve an aggregate radiation pattern in an end-fire direction. In some embodiments, each antenna element includes two pairs of antenna arms, a pair on either side of the substrate. In some embodiments, each pair of antenna arms are configured to be adjusted and positioned symmetrically to generate the end-fire radiation pattern. In some embodiments, each of the antenna elements in the linear array is spaced apart from each other by a distance that is equal to approximately λ/2, where λ is a wavelength associated with a frequency within a desired operating frequency range of the antenna system.

Abstract: Devices, systems, and methods for a compact beam-steerable antenna array for centimeter-wave and millimeter-wave mobile terminals, the antenna array having a steerable beam without phase shifters. In some embodiments, an antenna array includes an active antenna element and at least one parasitic element spaced apart from the active antenna element. An impedance between each of the at least one parasitic element and a ground element is tunable to steer a signal beam at the active antenna element in a desired direction.
