Abstract
A fingerprint sensor comprising a plurality of electrically conductive sensing structures arranged in a sensing plane for capacitively sensing a fingerprint of a finger placed on the finger receiving surface of the fingerprint sensor arrangement, the plurality of electrically conductive sensing structures including: a first set of electrically conductive sensing structures, each sensing structure in the first set of electrically conductive sensing structures covering an area in the sensing plane being within a first area range; and a second set of electrically conductive sensing structures, each sensing structure in the second set of electrically conductive sensing structures covering an area in the sensing plane being within a second area range only including areas greater than the areas within the first area range.
