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

In this paper, an analytical model is presented to investigate the resonant characteristics of a graphene rectangular microstrip patch antenna. To take into account the graphene film patch in the full-wave spectral domain technique, surface complex impedance is considered. This impedance is determined by using Kubo formula. A set of roof top sub-domain basis functions are employed to model the current density distribution on the graphene rectangular microstrip patch. The simulation results demonstrate that the designed structure can provide excellent tunable properties in Terahertz frequency region by varying different chemical potentials and relaxation times of graphene film. Variations of dimension of rectangular patch on the resonant frequency and bandwidth of a graphene rectangular microstrip antenna are presented. Finally, numerical results for the dielectric substrates effects on the operating frequencies are also presented. The analysis is validated by comparing the results with a specific example in the literature.
