5 GHz to 70 GHz Double Ridged Broadband Waveguide Horn Antenna, V-Female Connector (1.85mm)
喇叭天线是面天线，波导管终端渐变张开的圆形或矩形截面的微波天线，是使用最广泛的一类微波天线。它的辐射场是由喇叭的口面尺寸与传播型所决定的。其中，喇叭壁对辐射的影响可以利用几何绕射的原理来进行计算的。如果喇叭的长度保持不变，口面尺寸与二次方相位差会随着喇叭张角的增大而增大，但增益则不会随着口面尺寸变化。在射频、微波和毫米波应用中，天线必然是最多被涉及到的元器件类别之一。这其中，诞生自20世纪初的喇叭天线一直沿用至今。从本质上说，喇叭天线属于波导的一个分支：一端为尺寸较大的矩形或圆形波导，另一端为尺寸较小的波导或同轴端口。
