Abstract

A liquid-metal reconfigurable Yagi-Uda monopole array is presented. The three-element array consists of driven and parasitic elements whose lengths can be tuned with pressure-driven liquid metal, resulting in an array in which directors can be transformed into reflectors, and in which elements can be tuned to different frequencies. The measured radiation patterns demonstrate single-axis beam steering at multiple operational frequencies from 1.95 to 4.11 GHz.
