Abstract. The problem of matching of array of planar dielectric waveguides with free space in a wide range of angles is solved. Infinite array of planar dielectric waveguides is considered. Array is excited by free space plane waves that incident on an array surface under the arbitrary angle of incidence. Numerical solution of boundary problem obtained with help of periodical boundary conditions and finite elements method is considered. Specific features of numerical model are discussed. Approximate solution for array of planar dielectric waveguides is considered. Comparison of results obtained with help of numerical and approximate solutions is presented. A way to improve the array matching with free space is proposed.

Keywords: integral millimeter wave antennas, planar dielectric waveguide, parallel plate waveguide, array of planar waveguides.
