适用于 EMC 测量的宽带定向天线

线性极化的 R&S®HF907 双脊波导喇叭天线是一种紧凑型宽带收发天线,适用频率范围介于 800 MHz 至 18 GHz。天线具有高增益和低 VSWR,可以测量微弱信号和产生高场强,不会引起任何严重的回波损耗。相较于传统的宽带喇叭天线,R&S®HF907 的独特之处在于整个频率范围内的辐射方向图仅有一个主瓣而没有明显的旁瓣。天线适合在 EMC 实验室中使用。

特性和优点

宽频率范围

只需单个天线即可覆盖整个频率范围

天线覆盖 800 MHz 至 18 GHz 的宽频率范围。只需单个天线即可覆盖整个频率范围,显著减少了测量时间和总测量成本。

恒定的高增益

用于测量微弱信号

天线设计精密,可在整个频率范围内实现恒定的高增益,支持在 EMI 测量等应用中测量微弱信号。

低 VSWR

用于产生高场强

天线具有低 VSWR,可以产生高场强,不会引起任何严重的回波损耗。因此,天线非常适合 EMS 测量。

辐射方向图仅有一个主瓣

定向方向图确保精确测量

天线采用独特设计,E 平面和 H 平面的辐射方向图在整个频率范围内仅有一个主瓣而没有明显的旁瓣。明确的定向辐射方向图可提供精确的测量结果。
