1. A method of manufacturing an assortment of radar sensors in different variant embodiments, the method comprising:
in a single production run, producing a plurality of identical base structures, each for a respective one of the radar sensors, the plurality of identical base structures each including:
a housing; and
a circuit board equipped with at least one radio-frequency module;
subsequent to the single production run:
applying a planar antenna structure on a first side of the circuit board of each of one or more of a first subset of the plurality of identical base structures, wherein each of the one or more of the first subset has a respective radome arranged over the respective first side of the respective circuit board so that the respective planar antenna structure faces the radome, with the at least one radio-frequency module of the respective radar sensor facing away from the radome; and
applying a hollow conductor structure on a first side of the circuit board of each of one or more of a second subset of the plurality of identical base structures, wherein each of the one or more of the second subset has a respective radome arranged over the respective first side of the respective circuit board so that the respective hollow conductor structure faces the radome, with the at least one radio-frequency module of the respective radar sensor facing away from the radome.
