A liquid-metal reconfigurable double-stub tuner

A liquid-metal reconfigurable double-stub tuner is presented. The double-stub tuner consists of two fluidic channels whose stub lengths L1 and L2 can be tuned with Galinstan liquid metal using pressure-driven flow. The measured input impedance of this tuner shows wide Smith Chart coverage.
