Microfluidically-Tuned Miniaturized Planar Microwave Resonators Conference Paper uri icon

abstract

  • This paper presents two frequency tuning techniques, applied to planar microwave lumped LC and CPW resonators. Both methods are based on employing the reactive loading effect of a fluid metal placed on top of planar microwave circuits. The frequency tuning is achieved by moving the fluid metal inside the micro-channel and on top of different sections of each resonator. Realization of tunable resonators using common PCB technology and PDMS structure is demonstrated. The metal fluidic used is a non-toxic eutectic alloy of Gallium, Indium, and Tin known as Galinstan. Two implemented prototypes are measured and tuning ranges of 1.45-2.35 GHz and 2.8-3.9 GHz are achieved for lumped LC and CPW resonators, respectively. 2014 IEEE.
