Abstract
The problem of the analysis and design of planar antennas on a dielectric slab loaded with a metal-strip grating is solved. Such antennas are capable of emitting of directional electromagnetic radiation in the millimeter-wave band. The two-dimensional diffraction model of the antennas is proposed. According to the model the radiation and scattering characteristics of the antenna are treated as a result of dielectric slab surface mode diffraction by the grating of finite extent. The analysis is based on the electromotive force technique. Some numerical results concerning the antenna characteristics in the specific case of a finite-periodic grating are given. An effect of an air gap between the slab and a metal ground plane is readily illustrated. Moreover, the problem of the antenna design aimed at the reduction of side lobes is considered. Applying the proposed analysis to the designed antenna, one can determine the deviation of the actual antenna characteristics from the desired ones thus correcting the design procedure if necessary.
