摘　　要：根据紧耦合阵列天线原理,本文提出了1种加载V型开口环结构的超宽带低剖面单极化紧耦合天线。该天线通过集成超宽带巴伦结构实现平衡馈电,加载V型开口环和介质匹配层结构实现宽带及宽角扫描阻抗匹配,可在6~19GHz频带内实现E面±60°的波束扫描(ActiveVSWR<2.0),同时剖面高度仅为0.069,,为低频6GHz处自由空间中波长,天线单元尺寸为3.75mm×3.75mm×3.45mm。According to the broadband principle of tightly coupled array antenna,an ultra wideband low profile monopolar tightly coupled antenna with V-shaped split ring structure is proposed in this paper.The antenna achieves balanced feed by integrating UWB balun structure,impedance matching by loading V-shaped split ring and dielectric matching layer structure,and E-plane can be realized in 6-19GHz frequency band±60°.At the same time,the profile height is only 0.069 Aj,A,is the wavelength in free space at low frequency 6GHz,and the antenna unit size is 3.75mm×3.75mm×3.45mm.
