Dielectric Grating Antennas.

Abstract
We present in this report a comprehensive and systematic study of dielectric grating antennas for use in millimeter wave systems. First of all, the feasibility of grating surface-wave structures for use as millimeter wave antennas is positively established on the basis of extensive numerical data for the case of infinitely wide gratings with uniform surface wave excitation at normal incidence. Secondly, a new approximation technique is introduced to obtain analytic formulas that are simple and useful for the practical design of grating antennas. Thirdly, the results for the normal incidence case are extended to the general case of oblique incidence, so that antennas of finite width can be rigorously investigated. (Author)
