本公司提供的OBS系列背腔螺旋天线是专为ECM,侦察,定向,遥感以及航行器齐平安装应用而设计。

这些螺旋天线可作为单独的天线组件使用或作为反射面卫星天线的馈源使用。
 

背腔螺旋天线结构紧凑,轻巧,在其整个工作带宽上均具备优越的阻抗匹配和辐射方向控制性能。

它是幅度匹配以及相位、增益跟踪的理想工具。天线间的性能一致性和频率无关特性使之成为航空器检测接收系统的理想首选。


背腔螺旋天线采用了两种极化方式:右旋或左旋圆极化。

背腔螺旋天线在设计上采用了极其严格的环境标准,可在恶劣的环境下稳定、可靠地工作。

我们可以根据客户的需求定制各种特殊规格,特别是对频率有特别要求的带宽螺旋天线。
