| 摘 要： | 本文介绍了一种能在平行板波导中产生旋转模式的共面波导馈电方式.用这一馈电方式馈电的同心径向线缝隙天线可以产生前向波束.该馈电方式具有平面结构、易于集成化等优点,还可用于毫米波波段.对馈电点位置及幅度相位的适当调整,也可用于空心锥形波束的馈电.计算机仿真和实验结果说明了本文的设计思路和设计方法可以满足工程需要.

| Abstract: | A planar feeding circuit is proposed in this paper,which is str uctured by co-planar waveguide and excites a rotating mode in parallel plate waveguide.A CA-RLSA fed by this circuit has a foresite beam.The structure is planar and available to integration and minimization even in millimeter wave band .It is also suitable to excite a CA-RLSA with a conical beam if parameters are properly changed.It is proved by the simulation and experiments that the mechanism and principle are reasonable. |
