- Abstract
This paper describes a method for the synthesis of one-dimensional scanning leaky-wave antennas based on metasurfaces with modulated surface impedance. Such antennas consist of a chain of subwavelength resonant elementary cells with two degrees of freedom, one of which is used to modulate the impedance of the metasurface and the other to dynamically change the radiation direction of the leaky wave. As an example of the proposed method application antenna based on a metallic corrugated structure was synthesized, which allows scanning in the range from 4° to 42° at 27 GHz and has a directivity from 26.4 to 30.1 dBi. Antennas of the described type allow to realize one-dimensional electronic scanning in a much simpler way than phased array antennas
