Abstract
A waveguide antenna for a radar antenna array, particularly for use in motor vehicles, includes a metal waveguide extending in an x direction and having a longitudinal axis, which, for the propagation of a radar wave of a first mode in the x direction, delimits an inner space, wherein in order to specifically convert the first mode to a second mode of the radar wave which is different from the first mode and to couple the second mode out of the waveguide, a plurality of structural elements arranged in the x direction are provided which extend into the inner space and wherein adjacent structural elements have a distance which is larger than half a waveguide wavelength of the radar wave of the first mode or larger than half a free-space wavelength, depending on which of the two wavelengths is smaller.
