摘要
提出了一种宽带双极化微带天线,应用于5G(Sub-6)通信和无线通信频段,双极化微带天线加载了周期性结构作为附属,提高了天线的阻抗匹配和增益特性,天线相对带宽分别为63.82%和61.70%。2个端口采用双孔径缝隙耦合和改进型馈电结构,避免了两端口馈线的交叉,实现了35 dB的端口隔离,3.1~6.2 GHz的工作频带完全覆盖5G(Sub-6)通信系统的工作频段且覆盖无线通信频段,对5G移动通信和无线通信的发展具有重要研究意义。
A broadband dual-polarization microstrip antenna is proposed for 5G(Sub-6)communication and wireless communication bands.The dual-polarization microstrip antenna is loaded with a periodic structure as accessory to improve the impedance matching and gain characteristics of the antenna.The relative bandwidth of the antenna is 63.82%and 61.70%,respectively.The two ports adopt dual-aperture gap coupling and improved feed structure to avoid the crossover of two port feeders,and a port isolation of 35 dB is achieved.The working band of 3.1~6.2 GHz completely covers the working band of 5G(Sub-6)communication system and wireless communication band,which is of important research significance for the development of 5G mobile communication and wireless communication.
