摘要
This document describes techniques and systems to generate a point-source model for simulating near-field effects from structures of an antenna. The techniques and systems generate, based on near-field values extracted from electromagnetic simulations, respective far-field radiation patterns for active elements and, in some cases, passive elements of the antenna array. The far-field radiation patterns account for electromagnetic interactions between the active elements and an antenna structure, which can include passive elements of the antenna array. The techniques and systems output the far-field radiation patterns, which are effective to simulate, using an asymptotic numerical method, electromagnetic interactions between the antenna array and at least one interaction structure. Using the described point-source model, engineers can quickly and accurately simulate electromagnetic interactions between the antenna array and the interaction structure for various configurations and applications of the antenna array.
