Abstract
A radar sensor device having at least one planar antenna device that includes a plurality of vertically oriented antenna columns which are configured as a sparse array in one plane in parallel at defined mutual distances and which each have at least two line-fed patch elements, the sparse array of antenna columns is designed to have such a minimal redundancy that the amount of defined distances among the antenna columns in the sparse array is at least equal to all of the different distances between any two antenna columns of a corresponding non-sparse array of a planar antenna device having the same antenna aperture and the same characteristics of the antenna columns, but is the most minimum possible number.
