Abstract:
1. A device for receiving or emitting an electromagnetic wave having a free space wavelength λ 0 between 1 mm and 1 m, comprising: a medium of solid dielectric material having at least a substantially planar first surface, the free space wavelength λ a plurality of conductor elements incorporated inside said medium, each conductor element being a wire of a predetermined length extending along a direction intersecting said first surface between a first end in proximity to said first surface and a second end away from said first surface, and two neighbour conductor elements being spaced apart from each other by a distance less than λ/10, wherein the second end being distant from the first end by a distance greater than λ/10, and wherein the conductor elements comprises a first point and a second point that are distant from each other by a curvilinear distance along the conductor element greater than λ/4, said first and second point being also distant from each other by a straight line distance greater than λ/10, at least one antenna element intended to be connected to an electronic device for receiving or emitting an electric signal, wherein at least one tuned conductor element among the conductor elements has its first end at a distance from said antenna element which is less than λ/10, and said tuned conductor element has a length H wire adapted to generate an electromagnetic resonance along said tuned conductor element corresponding to said wavelength λ.
