Frequency-Reconfigurable Dipole Antenna Using Liquid-Metal Pixels

Figure 1

(a) Baseline planar dipole antenna to compare to liquid-metal pixelated equivalent. (b) Liquid-metal pixelated dipole prototype filled with liquid metal. (c) Top side with zoom-in of pixels. The left pixel is in the “on” state, with liquid metal present and interfacing with stainless steel placed within the walls between pixels. (d) Bottom side with zoom-in of pixels. The right pixel is in the “off” state. (e) Side view.
