摘要

本文介绍了辐射槽的光束倾斜特性。在电磁干扰/电磁兼容测试中测量辐射场强时，由于接收天线或探头的波束倾斜特性，必须沿其垂直轴移动。用近场测量系统测量了辐射方向图，并用时域有限差分法(FDTD)进行了验证。利用近场数据进行近远场变换，得到远场图。在10.82 GHz时，波束倾斜约为18 /spl度，FDTD法测量结果良好。

Analysis of beam tilting behaviour for the measurement of EUT radiating slots

In this paper, beam tilting behavior of radiating slots is introduced. When the radiating field intensity is measured in EMI/EMC test, the receiving antenna or probe must be moved along its vertical axis because of its beam tilting behavior. The radiation pattern is measured by near-field measurement system and verified by the finite difference time-domain (FDTD) method. The far-field pattern was obtained from near far field transformation by using near-field data. The beam tilted about 18 /spl deg/ at 10.82 GHz and the FDTD method provides a good result to this measurement.
