A signal sensor is provided that includes a substrate, an input port formed on the substrate as a substantially linear conductive element, and a sensing port formed on the substrate adjacent to the input port. The sensing port is influenced by magnetic flux emanating from the input port such that a sense signal is generated in the sensing port. The sensing port can have as little as one sensing loop disposed on one side of the input port, but preferably includes at least one sensing loop on each side of the input port. The sensing loops on each side of the input port have an opposite sense of turn so that the sense signals in each loop are additive. A cross-over connector provides an electrical connection between the loops of the sensing port on opposite sides of the input port. The cross-over connector can be an underpass crossing below the input port or an overpass crossing above the input port. If desired, multiple sensing loops can be formed on each side of the input port. These sensing loops may be formed at the same fabrication level or may be formed on multiple fabrication levels. In the latter case, multi-level interconnects provide electrical connections between the sensing loops on each level.
