【摘要】 本文基于开口圆波导结构提出了一种双模共口径辐射天线。天线工作在8 mm波段,具有定向辐射与锥状辐射两种辐射模式。定向辐射模式由圆波导主模TE11模式作为基础,具有约10 dBi的增益,而锥状辐射模式则依赖于圆波导高次模TM01模式,增益约为6~7.5 dBi,两种模式均采用耦合馈电的方式进行激励,从而尽量避免安装误差。两种辐射模式同时覆盖33.2 GHz~36.8 GHz频段,端口隔离度超过43 dB。
【Abstract】 In this paper,a dual-mode shared-aperture radiating antenna is proposed based on the open circular waveguide structure.The antenna works in the 8 mm band and has two radiation modes:directional radiation and cone radiation.The directional radiation mode is based on the circular waveguide main mode TE11-mode with a gain of about 10 dBi,while the conical radiation mode relies on the circular waveguide higher mode TM01-mode with a gain of about6~7.5 dBi.Electric way to stimulate,so as to avoid installation errors as much as possible.The two radiation modes simultaneously cover the 33.2 GHz~36.8 GHz frequency band,and the port isolation exceeds 43 dB.
