Antenna inlay for a document and document with such an antenna inlay

Antenna inlay for a document, comprising:

• an inlay substrate foldable along a folding line;
• an antenna formed on or embedded into the inlay substrate;
• and
• a bridging substrate almost completely covering the inlay substrate for completely overlaying the antenna, wherein at least one bridge material portion is defined in the bridging substrate by lateral cutout gaps along the folding line,
• wherein the antenna comprises a first antenna portion routed outside the folding line and at least one conductive bridging portion routed to extend across the folding line,
• wherein the at least one conductive bridging portion is electrically connected with the first antenna portion,
• wherein the at least one conductive bridging portion is routed at the folding line so as to cross the folding line at an inclination angle unequal to 90°,
• wherein the at least one conductive bridging portion is routed in a zig-zag or meander-like or triangular or sawtooth or sinusoidal shape relative to the folding line, and
• wherein the lateral cutout gaps are formed as zig-zag or meander-like or triangular or sawtooth or sinusoidal shaped cutouts matching a routing shape of the at least one conductive bridging portion and aligned therewith.
