Abstract
A leaky-wave antenna using a grounded dielectric-artificial dielectric (AD) slab is described. The propagation constant of this structure is evaluated by solving the dispersion relation. Various modes supported by this structure are discussed. This type of leaky-wave antenna is capable of producing extremely narrow beamwidths. An antenna using the dielectric-AD is compared with the AD antenna reported in [1]. It is found that for similar characteristics this modified antenna structure requires smaller thickness than the AD antenna. Theoretical and experimental results for radiation characteristics of this type of antenna are compared and found to be in good agreement.
