The invention discloses an adjustable two-dimensional
beam scanning element
grating leaky-wave antenna and an analytic solution method, and belongs to the technical field of leaky-wave antennae, the antenna comprises an upper element light layer structure and a lower element light layer structure, an embedded
liquid crystal is integrated in the lower element light layer, and a variable
capacitance diode array is embedded in the upper element light layer. The analytic solution method comprises the following steps: S1, independently carrying out electromagnetic characteristic analysis on each element
grating element, and decomposing a
wave field into discrete space
harmonics; s2, calculating and modeling adjustability provided by the embedded
liquid crystal and the variable
capacitance diode array; s3, integrating each
individual analysis result into a complete multilayer
electromagnetic model; and S4, verifying the analysis solution. According to the invention, scanning in two
radiation directions of a horizontal plane and a
vertical plane can be realized, the efficiency of a
communication link in a complex
urban environment can be improved by adaptively adjusting the
beam direction, and the method is of great significance for realizing performance targets of
high data rate,
low delay, connection of a large number of devices and the like.
