Abstract (en)
A microstrip multi-resonator tunable filter (F) includes: a substrate (1) having arranged thereon one or a plurality of a microstrip resonators (3), and a dielectric element (4) arranged facing the microstrip resonators (3) at a selectively variable distance (D) to the substrate (1). Varying that distance (D) permits to uniformly vary the resonating frequency of the microstrip resonators (3).
