An Electrically Actuated Liquid-Metal Gain-Reconfigurable Antenna
Figure 4
Liquid-metal gain-reconfigurable antenna states. (a) 0 mm offset state: the midpoint of the Galinstan slug coincides with the center of the 50 Ω copper microstrip feed line; (b)–(d) -mm-offset state: the midpoint of the Galinstan slug is mm from the center of the microstrip feed line. The Galinstan slug is 1.5 × 15 × 0.6 mm3.
