Directional diagram reconfigurable pixel antenna optimization method based on built-in multi-port algorithm

The invention provides a directional diagram reconfigurable pixel antenna optimization method based on a built-in multi-port algorithm, which is used for solving the technical problem of poor stability of a non-reconfigurable part of a reconfigurable antenna in the prior art. The method comprises the implementation steps of determining the structure and an optimization object of a to-be-optimizedantenna, calculating the radiation characteristic of the to-be-optimized antenna by adopting a built-in multi-port algorithm, optimizing the structural parameters of the antenna by adopting a particleswarm algorithm, and optimizing the on-off state distribution of the antenna by adopting a binary genetic algorithm to obtain an optimized directional diagram reconfigurable pixel antenna. Accordingto the method, by adding the optimization process of the structural parameters, the stability of the non-reconstructed part of the reconfigurable antenna is improved on the basis of ensuring the optimization efficiency the same
