This paper presents a design approach for a dualpolarized planar antenna array for use within a polarizationagile radar system operating in the frequency range from 76 GHz to 77 GHz. A multilayer stack of organic microwave laminates is used to reach a dense integration of antenna elements and feed lines. This allows to fit individual antenna elements capable of radiating in two orthogonal linear polarizations into a near half-wavelength grid to form a two-dimensional, dual-polarized, planar antenna array.
