Abstract

The invention relates to the technical field of suspension surface improvement methods, and discloses an adjustable axial ratio circular polarization decoupling improvement method for a suspension surface, and the method comprises the following steps: S1, selecting a dual circularly polarized antenna array; s2, reducing the array element spacing d; s3, formulating a same / different polarization hybrid decoupling scheme and corresponding design parameter indexes; s4, axial ratio adjustable improvement and corresponding design parameter indexes are formulated; s5, building a circular polarization decoupling suspension surface with the adjustable axial ratio; and S6, selecting an air dielectric plate as a support plate, setting the distance h between the suspension surface and the antenna array, and setting the length wpx of the reflective metal patch. According to the invention, the hybrid decoupling capability is improved, the axial ratio and the cross polarization are improved, the miniaturization and integration design is supported, the adaptability of broadband and multi-band operation, the communication efficiency and the system reliability are improved, the large-scale array scanning and satellite communication are supported, and the processing and cost challenges are reduced.
