本文讨论了一个实验性的Ka波的(37GHz)透镜天线,它在最小实用锥角之外具有—40分贝或更低的旁办电平。将结果与最佳台劳方向图(以同样的口径,在满足上述旁办要求的情况下,视轴方向性最大)作了比较。测量了厚的均匀球形天线罩对旁办的影响,并与普通的反射面天线作了比较。 This article discusses an experimental Ka-wave (37GHz) lens antenna with a side-by-side level of -40 dB or less beyond the minimum practical cone angle. The results were compared with the best-fit workaround pattern (with the same caliber that maximizes the boresight direction when meeting the by-side requirements above). The effect of a thick, uniform spherical radome on the sidewalk was measured and compared with a conventional reflector antenna.
