Design of elliptically polarized millimeter wave antenna arrays

Józef Modelski , Jacek Jarkowski , E. Yashchyshyn


The results of design and investigations of elliptically polarized millimeter wave antenna arrays are shown. A presented leaky-wave antenna array consists of the waveguide structure and a finite diffraction grating. The diffraction grating is excited by an E-type surface wave, which is the eigenwave of the waveguide structure. The diffraction grating consist of rectilinear and parallel nonhomogeneities, which are disposed at an angle of alpha; in the direction of surface wave propagation. The angle alpha;, widths and distances between nonhomogeneities are chosen by using special optimization algorithms in order to obtain the necessary electrodynamic characteristics
