Abstract

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 as that in the prior art, and the method has higher engineering practical value. The method can be applied to optimization design of the directional diagram reconfigurablepixel antenna.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to an antenna optimization method, in particular to a method for optimizing a reconfigurable pixel antenna of a pattern based on a built-in multi-port algorithm, which can be applied to the optimization of a reconfigurable pixel antenna of a pattern, and can improve Stability of the non-reconfigurable part of the antenna. Background technique [0002] The rapid development of wireless communication has made wireless systems increasingly complex. Faced with more complex requirements, the system is often required to work in multiple scenarios. Reconfigurable antennas can adjust the resonance length and current path of the antenna without changing the overall structure. Realizing different radiation characteristics can well meet the needs of current wireless systems for multi-scenario work. [0003] The radiation characteristics of the antenna mainly include the reflection coefficient ...
