Three basic problems associated with dielectric grating antennas are investigated. First, the radiation characteristics in the stopband region are carefully analyzed, showing the range of blindness of the antenna in the broadside direction. Second, a new perturbation procedure for grating antennas is shown numerically to yield accurate propagation characteristics including the changes in phase as well as decay constant. Finally, the scattering of a plane wave by a dielectric grating at an arbitrary incidence angle is analyzed showing the coupling between TE and TM modes. Author
