A dielectric leaky-wave antenna (DLWA) coupled with a metallic diffraction grating is experimentally investigated in millimeter-waves. The interaction between dielectric line and grating is from the narrow-face of dielectric and it is contactless. Measured patterns are compared with simulated ones. The antenna parameters (HPBW, side lobe levels, etc.) are also obtained. The most significant achievement of this antenna is to obtain broadside radiation without any suppression, which occurs due to the periodicity of grating. This situation is not available for the most of the periodic leaky-wave antennas. This antenna type can be used as a broadside radiator by this property as well as a frequency scanning purposes.

“…There are some differences between our proposed structure and known DLWAs in the literature such as inverted-strip DLWAs[2,3] and periodically metal-strip loaded DLWAs[4][5][6][7][8][9][10][11][12][13][14][15] in terms of the perturbation style and physical constructions of the antennas. These differences were explained in[16] 2.…”

“…In this structure, bound surface waves (slow wave) interacts with the periodic diffraction grating and some part of this wave transforms to the volumetric propagating wave (fast wave). This type of structure can be classified as a leaky-wave antenna [3,4] in general and dielectric leaky-wave antenna (DLWA) [5][6][7][8][9][10][11][12][13][14][15][16][17] in particular. There are examples of DLWA in the literature.…”

The millimeter wave radiation of a dielectric leaky-wave antenna (DLWA) coupled with a metallic diffraction grating with a sinusoidal height profile is experimentally investigated. The interaction between dielectric and grating is contactless and it is from the broad-face of the dielectric line. The measured field patterns are compared with the simulated HFSS patterns. Antenna parameters such as polarization, HPBW, crosspolarization and side lobe levels are measured. The effects of the geometrical parameters of the grating to the radiation are also investigated. Some results are compared with a DLWA which has another diffraction grating profile shape (rectangular). The investigated antenna can be used as a frequency scanning antenna in mm-wave radars because it has low cross and side lobe levels and narrow beam width.

The radiation characteristics, main applications, design techniques, and practical implementations for the class of leaky‐wave antennas are considered. The basic relations between the propagation properties of open waveguides, on which these antennas are based, and the relevant features of the radiation patterns are discussed, exploiting the leaky‐wave concept. The principal radiative properties as main‐beam direction, beamwidth, radiation efficiency, scanning behavior, and sidelobe level are described. The various steps of a practical design are outlined. Examples of proposed structures derived from metallic, dielectric, and printed waveguides are reported. Accounts for measurement procedures and practical operation are given.
