Antenna arrangement for a radar measuring device and radar measuring device

Abstract

An antenna array (200, 300, 400, 500, 600, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600) for a radar measuring device (40) and a radar measuring device (40) with an antenna array (200, 300, 400, 500, 600, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600) are provided. The radar measuring device (40) has a radiation source (10). The antenna arrangement (200, 300, 400, 500, 600, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600) comprises at least one input lens (102) and one output lens (103). The input lens (102) is configured to focus electromagnetic waves emitted by the radiation source (101) towards the output lens (103).A distance between at least the input lens (102) and the output lens (103) along a longitudinal direction of the antenna arrangement (200, 300, 400, 500, 600, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600) depends on a frequency of the electromagnetic waves emitted by the radiation source (101) such that the antenna arrangement (200, 300, 400, 500, 600, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600) provides electromagnetic waves for an external component based on the output lens, which have a substantially planar wavefront (206).
