Abstract
A device for receiving and/or emitting an electromagnetic wave having a free space wavelength λ0 comprised between 1 mm and 10 cm, comprising a medium (11) of solid dielectric material and the free space wavelength λ0 corresponding to a wavelength λ inside the medium, a plurality of conductor elements (12) incorporated inside the medium and spaced apart from each other of a distance lower than λ/10, and one antenna element (13). The conductor elements are not loop elements. A tuned conductor element among the conductor elements has a first end at a distance from the antenna element which is lower than λ/10, and has a length Hwire adapted to generate an electromagnetic resonance in the tuned conductor element corresponding to the wavelength λ.
