Abstract

An antenna includes a probe capable of transforming electrical energy into electromagnetic energy and inversely. It further includes an assembly of elements made of at least two materials different in permittivity and/or permeability and/or conductivity within which the probe is arranged, the arrangement of the elements in the assembly ensuring radiation and spatial and frequency filtering of the electromagnetic waves produced or received by the probe, which filtering allows in particular one or several operating frequencies (f) of the antenna inside a frequency band gap (B).
