摘要：
A leaky-wave bifocal linear array focused in the Fresnel zone is considered. The structural parameters provide perfect focusing of the field at two points corresponding to two different frequencies. An approximate theory of antenna arrays is used to analyze the bifocal array, to study the shape of the frequency scanning arc, and to determine the field distribution in the focal spot. An electromagnetic simulation is performed for a strip array with slotted radiators. The scattering parameters of the array and its radiation characteristics are presented. The design features of a strip antenna that suppress the effect of normal are discussed. The results of an experimental study of a strip bifocal array are presented. The possibility of implementation of a symmetrical scanning arc and a relatively low level of optical aberrations is shown.
