摘要
介绍了采用准光方法激励圆波导产生旋转TE6 2模式的设计原理、测试方法和实验结果。该模式产生器由毫米波光学系统和开放同轴波导谐振腔系统组成:毫米波光学系统由角锥喇叭天线、双曲面反射镜、抛物面反射镜、修正抛物面反射镜等部件组成;开放同轴波导谐振腔系统由开放同轴波导谐振腔、圆波导、测试辐射喇叭天线组成。通过网络分析仪和毫米波近场自动测试系统测试表明:该模式产生器在频率为96.4 GHz附近产生的圆波导旋转TE6 2模式的纯度达到97%。
Abstract
The design, measurement technique and experimental results of rotating TE6 2 mode generator are presented. The source includes millimeter wave optical system and open coaxial wave guide system. The millimeter wave optical system consists of pyramid antenna, hyperbolical reflector, parabolic reflector and quasi parabolic reflector. The open coaxial wave guide system contains open coaxial wave guide cavity, cylinder wave guide and output antenna. It is tested by network analyser and millimeter wave near field pattern auto-test system, and the purity of rotating TE6 2 mode at 96.4 GHz is about 97%.
