Decoupling methods for dielectric resonator antennas:a systematic review and emerging prospects
摘要
Abstract
Dielectric resonator antennas(DRAs),characterized by their compact size,high radiation efficiency,and flexible degrees of design freedom,have emerged as promising candidates for highly integrated wireless communication systems in the 5th and 6th generation mobile communication technology(5G and 6G).However,strong mutual coupling among elements in densely-packed arrays severely degrades system performance,making decoupling techniques a key research topic.This paper reviews the advances in DRAs and their decoupling methods,and classifies the decoupling approaches into two categories:structure-based decoupling strategies and self-decoupling strategies.The former include field-blocking,polarization-orthogonality,and field-cancellation methods,whereas the latter encompass mode-cancellation methods and other DRA-specific self-decoupling approaches.The operating principles of these methods are described in detail,and their representative designs and performances are analyzed and evaluated.The analysis shows that,owing to the rich modal characteristics and design flexibility of DRAs,self-decoupling strategies can achieve efficient decoupling without introducing external structures.Finally,major challenges are discussed,including the limited bandwidth of high isolation,the difficulty of balancing isolation and radiation performance in broadband high-isolation designs,and the increasing number of coupling paths as well as the growing complexity of mode control in multi-port arrays.Future research directions are further outlined,covering coordinated multi-mode and multi-path decoupling,systematic self-decoupling theory for multi-port systems,and robust engineering implementation.This review is expected to provide a useful reference for the design of high-performance DRA arrays.关键词
