A frequency-tunable microstrip patch antenna with a liquid-metal-actuated loading slot is presented. The electrical length of the loading slot located beneath the resonating patch is altered by filling and evacuating liquid metal from fluidic channels along the ground plane. The slot reactively loads the antenna, altering the resonant frequency as its length is changed. Frequency tuning is achieved from 1.85 to 2.07 GHz, corresponding to an 11.2% tuning bandwidth.
