Claim:
1. A high-impedance passive device to provide a given radio-electric decoupling between two separated antennas operating at least partially in a common frequency band and already arranged on a surface of a carrier structure, comprising a substrate comprising a flexible dielectric material layer of a predetermined thickness with patches disposed on a surface of the flexible dielectric material layer, the patches being made of conducting material exhibiting a predetermined geometry and a predetermined arrangement; and an attachment layer to fix the high-impedance passive device on a ground plane on the surface of the carrier structure such that the flexible dielectric material layer formed by the patches is separated from the surface of the carrier structure by a substrate thickness, which is determined as a function of the predetermined geometry, a number and the predetermined arrangement of the patches, and aerodynamic constraints imposed on the high-impedance passive device exhibiting an impedance to produce the given decoupling in the common frequency band.
