Performance Evaluation of Microfluidically Tunable Microwave Filters

This paper presents a contribution to evaluating the performances of tunable devices devoted RF applications. It is based on reconfiguration by fluids capacitor/inductor associated in monolithic substrate. Indeed, association two microfluidic passive same wafer allows us increase total frequency response microwaves structures. The study evokes presence and displacement different conductive dielectric liquids structure microchannels. theoretical analysis concerns devices, capacitor inductor, parallel topology. obtained results show good agreement between electrical parameters microwave response. Furthermore, significant variation from 370 MHz 1720 achieved, with tuning range that reaches 364.8%. experimental part exhibits fabrication characterization structures order evaluate actuation for architectures: pass-band filter (presented prior work) stop-band filter. are modeled behavior demonstrate large
