Abstract (en)

Compact multiband antenna (1) comprising at least one metallic element (2), for the reception of radio-frequency signals relating to a plurality of frequency bands, and a multilayer printed circuit (3; 103), combined with the metallic element (2), provided with a first end layer (4; 104), made of conductive material and on which a plurality of electronic components (5) are arranged to create at least a first electronic circuit, and a second end layer (6; 106) opposite the first (4; 104), also made of conductive material and on which a plurality of electronic components (7) are arranged to create at least a second electronic circuit. The multilayer printed circuit (3; 103) comprises at least one intermediate layer (8; 108), made of conductive material and separated from said first and second end layers (4, 6; 104, 106) by one or more layers of insulating material (9; 109), said at least one intermediate layer (8; 108) constituting an earth reference electrically connected to said electronic circuits and suited to electromagnetically separate said first and second end layers (4, 6; 104, 106) from one another.
