The invention discloses an antenna near-field
coupling partitioning method for scattered
radiation collaborative design of a planar antenna, and relates to the technical field of antennas. The method comprises the following steps: acquiring
electromagnetic field distribution data of an antenna under a target working frequency; then, according to the
electromagnetic field distribution data, calculating a
field function partition criterion index of the space around the antenna, so as to divide a function area of the near field of the antenna; and finally, according to the
field function partition criterion index, dividing the function areas of the near field of the antenna, and loading different electromagnetic function structures in different function areas. According to the method, a systematic and quantifiable design criterion is adopted, the method is used for near-field
coupling partition of the planar antenna, the
layout of electromagnetic functional structures with different functions is guided, and therefore the collaborative decoupling design of the
radiation performance and scattering performance of the antenna is achieved.
