摘要

提出了一种具有周期缝隙的波导型漏波天线。通过连接到槽的开关二极管，可以以单一频率扫描光束。所述槽的组合被选择性地激发，以使光束向所希望的方向移动。通过改变光束的组合，可以在60度到120度的范围内对光束进行离散扫描。测量的辐射模式与理论预测一致。二极管损耗相对较小。

Waveguide-type discrete beam-scan antenna with switching diodes

A waveguide-type leaky wave antenna with periodical slots is proposed. The beam can be scanned at a single frequency by switching diodes connected to the slots. A combination of the slots is excited selectively so as to make a beam to a desired direction. By changing the combination the beam can be scanned discretely from 60 deg. to 120 deg. Measured radiation patterns agree with theoretical predictions. The diode loss is comparatively small.
