1. A sensor package comprising:
a non-conductive substrate;
at least two electrically conductive coils located at a first side of the non-conductive substrate;
an evaluation circuit located at a second side of the non-conductive substrate opposing the first side of the non-conductive substrate; and
conductive connections between the at least two electrically conductive coils and the evaluation circuit,
wherein the evaluation circuit is configured to determine a position of the target and/or a change of position of the target,
wherein the at least two electrically conductive coils include a transmitting coil and a plurality of receiving coils,
wherein an area covered by the transmitting coil is larger than an area covered by at least one of the receiving coils,
wherein the plurality of receiving coils are arranged on an outer circumference of the transmitting coil which has a shape of a circle such that the areas of each of the plurality of receiving coils at least partially overlaps with the area of the transmitting coil, and
wherein center points of the plurality of receiving coils are distributed along the outer circumference of the transmitting coil.
