摘　　要：对卫星便携站的馈源喇叭进行了研究,并设计了一款新结构的介质加载馈源喇叭天线,以替代该卫星便携站原有的波纹喇叭馈源。该介质加载馈源喇叭天线的特点是结构简单、组装简易、成本低廉。通过比较和分析,该天线具有增益高、反射小、交叉极化低、波束对称及波瓣尖锐的优点,尤其是天线的口径效率最高可达到95.7%。可见介质加载馈源喇叭非常适用于卫星便携站的馈源以及卡塞格伦天线的初级辐射器。A type of portable satellite station feed horn antenna is studied. A novel feed horn antenna loaded with dielectric is designed in order to replace the original corrugated horn antenna.The feed horn antenna loaded with dielectric is characterized by simple structure,easy assembly and low cost.Through comparison and analysis,the proposed antenna has such advantages as high gain,small reflection,low cross-polarization level,symmetrical beam,and sharp lobe. In particular,the antenna aperture efficiency can be up to95.7%.Therefore the feed horn antenna loaded with dielectric is a perfect candidate for portable satellite station and primary radiator of Cassegrain antenna.
