Abstract

A multibeam antenna based on a Morgan double-layer lens in the form of plane waveguides coupled via a frequency-periodic array is investigated. The lens synthesis problems are considered. The analytical model of coupled plane waveguides is constructed. The model uses the equivalent boundary conditions. It is verified using the electromagnetic modeling in the HFSS system. An approximate electromagnetic model of the antenna is proposed. The model is based on the representation of the structure electromagnetic field inthe form of radial waves of coupled plane waveguides of the fundamental type. It is shown that, in the doublelayer lens, the effect of its shading by irradiators is substantially attenuated. This fact makes it possible to form the system of rays with fan-shaped patterns, which provides for the space view in the azimuth angle sector of 360°. The possibility of formation of narrow rays with the low level of the side and back irradiation is demonstrated.
