摘要

提出了一种基于衬底集成波导的平面偏馈卡塞格伦h面喇叭天线。由于副反射器和进给器位于主反射器的孔径之外，可以避免阻塞效应。通过对两个反射镜的合理设计和进给角的合理位置，可以实现相位的基本均匀分布。在27.5 GHz ~ 32.1 GHz工作频段内，可实现H面窄波束宽度和E面宽波束宽度，且辐射方向图稳定。

Offset-feeding cassegrain H-plane horn antenna based on substrate integrated waveguide

A planar offset-feeding Cassegrain H-plane horn antenna based on substrate integrated waveguide is proposed in this paper. Blockage effect can be avoided because the sub-reflector and feed are located out of the aperture of the main reflector. Almost uniform phase distribution can be realized by proper design of the two reflectors and the location of feeding horn. A narrow beamwidth in H plane and wide beamwidth in E plane can be achieved, and the radiation pattern is stable in the operating band from 27.5 GHz to 32.1 GHz.
