Filtering antenna design method

The invention relates to the technical field of antenna design methods, in particular to a filtering antenna design method which comprises the following steps: S1, a classification module classifies functions of a to-be-designed filtering antenna to obtain information that the to-be-designed filtering antenna belongs to a low-loss filtering antenna or a lightweight filtering antenna, and transmits the information to an antenna material performance evaluation module; s2, an antenna material performance evaluation module evaluates the performance of a dielectric material according to the information that the to-be-designed filtering antenna belongs to the low-loss filtering antenna to obtain the information that whether the dielectric material is qualified, and evaluates the performance of a conductive material according to the information that the to-be-designed filtering antenna belongs to the light-weight filtering antenna to obtain the information that whether the conductive material is qualified; and S3, s
