在电磁辐射领域，"波束宽度"一词通常指的是两个关键概念：半功率波束宽度（Half-Power Beamwidth, HPBW）和第一零点波束宽度（First Null Beamwidth, FNBW）。它们在工程实践中扮演着重要角色，但它们之间确实存在差异，而非简单的同义替换。</ 首先，让我们澄清一下术语。在天线方向图的讨论中，我们通常...
讨论天线的波束宽度，常涉及两个概念：半功率波束宽度（HPBW）和第一零点波束宽度（FNBW）。HPBW定义为天线主瓣在某一剖面上功率下降至最大值的一半（即3dB）时的宽度。这是工程上常用的波束宽度衡量指标。FNBW则定义为主瓣功率下降至最大值的某个特定点（通常是0dB或最大值的一半）时的宽度。FNBW在...

The half-power point is the angle off boresight at which the antenna gain first falls to half power (approx. -3 dB) from the peak. The angle between the -3 dB points is known as the beamwidth. Customer Service Sales Phone:400 820 5857Landline:800 820 5279 Technical 400 820 3793 ...
