A low profile Planar Inverted-F Antenna comprises a radiating strip, an inductive tuning portion, a vertical feed portion, and a retracted ground plane. A control node partitions the interference diagram between the communication of the first couple and the communication of the second couple, into different areas, each area being associated to a type of processing of the interference. An illuminant epitaxial structure is provided, in which the illuminant epitaxial structure has a first surface and a second surface on opposite sides, and a substrate is deposed on the first surface of the illuminant epitaxial structure.
