La bande d'isolation est disposée verticalement au-dessus du substrat diélectrique, et le centre de la bande d'isolation coïncide avec le centre de l'antenne MIMO. Dans la présente invention, l'antenne MIMO est formée de quatre éléments d'antenne identiques disposés selon une rotation de 90 degrés autour du centre, et un procédé de chargement d'une tige métallique de court-circuit d'antenne planaire est utilisé, de telle sorte que l'aire de l'antenne est réduite de moitié par rapport à celle d'une antenne planaire demi-onde classique, et la structure de celle-ci est compacte; une technologie d'impression microruban est utilisée, de telle sorte que l'antenne présente un degré d'intégration plus élevé, est plus légère, moins coûteuse et présente un cycle de traitement plus court; et l'utilisation de la bande d'isolation verticale permet au coefficient de corrélation entre les ports d'antenne d'être réduit, et, en comparaison avec d'autres techniques de découplage, la structure est plus compacte tout en garantissant un effet d'isolation élevé.
