<p>The invention concerns electronic radio frequency identification in the ultra-high frequency (UHF) range, to mark a product (2) for identification in a metallic environment. For this purpose, an electronic device (1) comprises at least one arrangement for adjusting impedance (15) in the shape of a meander with conductor length (L) compensation. This meandering conductor arrangement (15) is connected to a first antenna (8) dipole (16) on an emission face (10) and to a conductive layer (12) of an earth face (7), while an electronic component (3) is connected to the first antenna dipole (16) by an internal interface conductor (9) in the form of a plated through hole (11) and to a second antenna dipole (18) by another internal interface conductor (9) in the form of a plated through hole (11), passing through the thickness of an upper level (4) of substrate.</p> |
