Abstract: Embodiments of the present disclosure provide an array antenna bandwidth enhancement method based on phase regulation and control, an apparatus and an array antenna, a reflection coefficient of the array is calculated utilizing a one-time-reflection model calculation formula determined based on a small reflection theory, thus saving a full-wave simulation time of a large-scale array, and greatly improving a design efficiency. Enhancement of a bandwidth of the array using the array bandwidth enhancement method based on phase regulation and control may save a time for stepwise increased and matching adjustment of the large-scale array, and reduce design complexity. The provided method is simple and efficient, and is beneficial to realization of a wideband design of the large-scale array antenna.

Abstract: The present disclosure provides a method and apparatus for determining an antenna array and an electronic device; the method includes: determining a first target reflection coefficient of each radiation element forming the antenna array based on a pre-acquired antenna array design index; determining a model structure of each radiation element based on the first target reflection coefficient; extracting an amplitude and a phase of a first reflection coefficient from a simulation result of the model structure of a specified radiation element; determining a second target reflection coefficient of each power divider forming the antenna array in a preset calculation mode; determining a model structure of each power divider based on the second target reflection coefficient; and determining the antenna array based on each radiation element with the determined structure and each power divider with the determined structure.
