According to the design method, the scattering parameter of a single slot isobtained through direct measurement, the operability is high, and the calculation of a beam pointing adjustable antenna directional diagram without depending on simulation software is realized; meanwhile, weighted calculation of a beam pointing adjustable antenna directional diagram is realized; key information including slot unit forms, slot unit combinations, slot unit arrangement modes and thelike can be globally optimized, and optimization of slot unit selection, arrangement, combination, spacing and the like in antenna design is greatly saved so as to focus on the design of slot unit structure forms; besides, the wave control codes of the conduction and cut-off states corresponding to the slot units can be calculated according to the beam pointing deflection requirements so that guidance is provided for regulation of beam pointing and thus rapid forming and switching of the beams can be realized.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a method and device for calculating the direction diagram of an antenna with adjustable beam direction. Background technique [0002] The waveguide-based beam pointing adjustable antenna (leaky wave antenna) has the advantages of low cost, long life, low profile, full shielding to eliminate internal complex scattering, etc. The key factors in the design of adjustable beam pointing antennas include: slot unit, slot spacing, slot arrangement, slot turn-on and cut-off control, etc. Among them, in order to achieve precise control of specific beam pointing and low sidelobe control in the working frequency band, it is necessary to optimize the linkage of the above key factors. [0003] The design method of the beam-pointing adjustable antenna with traditional regular slots is relatively mature, and factors such as slot size and spacing are related to the antenna pattern forme...
