A method for determining a distance to a target comprises: receiving a bitstream of binary digits corresponding to a time-varying signal based on light transmitted by a light source being reflected by the target, wherein each binary digit in the bitstream is defined based on the time-varying signal at a time instance represented by the binary digit being above or below a threshold; comparing the bitstream to a set of stored reference bitstreams, wherein the set comprises pairs comprising a first reference bitstream and a second reference bitstream representing a common distance to the target, wherein the first reference bitstream is phase-shifted in relation to the second reference bitstream; and determining the distance to the target based on selection of a pair of reference bitstreams based on said comparing.

Method and a device for determining a distance to a target

Example embodiments relate to monolithically integrated antenna devices. One embodiment includes a monolithically integrated antenna device that includes a substrate having a first surface and a second surface. The monolithically integrated antenna device also includes a transistor component layer that includes at least one electronic component therein. Further, the monolithically integrated antenna device includes at least one antenna structure formed on the substrate or the transistor component layer. The antenna structure is configured to operate in a frequency range of between 30 kHz and 2.4 GHz. The substrate is configured to have a size that is the same or larger than the at least one antenna structure. The at least one antenna structure is formed in a stack with the transistor component layer and the substrate. The monolithically integrated antenna device is configured to shield the at least one electronic component in the transistor component layer from electromagnetic interference.
