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.
