Abstract
A differential filtering device with coupled resonators, including: a pair of coupled resonators disposed on one and the same face of a dielectric substrate, each resonator including two conducting strips positioned in a symmetric manner with respect to a plane perpendicular to the face on which the resonator is disposed, these two conducting strips being joined respectively to two conductors of a bi-strip port for connection to a line for transmitting a differential signal, wherein each conducting strip of each resonator is folded back on itself so as to form a capacitive coupling between its two ends, and wherein the two resonators of the pair are coupled by the disposition opposite one another of their respective conducting strips disposed on the same side with respect to the symmetry plane, over respective portions of length of these folded-back conducting strips.
