Abstract (en)
[origin: EP2184801A1] The device (10) has resonators (12, 14) coupled on a same plain face (16) of a dielectric substrate. Each resonator includes conductive strips (LE1, LE2, LS1, LS2) positioned in a symmetric manner with respect to a symmetry plane (P) perpendicular to the substrate plain face. Each conductive strip of the resonator is folded on itself in a manner to form a capacitive linkage. The resonators are coupled by arrangement of their respective conducting strips disposed on a same side with respect to the symmetry plane, over respective portions of length of the folded conducting strips. An independent claim is also included for a differential filtering dipole antenna comprising a radiating structure for integrating a differential filtering device.
