Abstract
A device for receiving and/or emitting an electromagnetic wave having a free space wavelength λcomprised between 1 mm and 10 cm, comprising a medium () of solid dielectric material and the free space wavelength λcorresponding to a wavelength λ inside the medium, a plurality of conductor elements () incorporated inside the medium and spaced apart from each other of a distance lower than λ/10, and one antenna element (). The conductor elements form small 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 an electric resonance frequency corresponding to the wavelength λ.
