【摘要】 本文介绍了一种带天线罩的毫米波单极子天线。该天线通过同轴馈电,天线由振子、天线罩、地板组成。天线地板采用了凸台形结构,这样有利于改善天线方向图上翘的问题。其机械结构的轴对称性保证了其电性能的轴对称性。这种天线结构简单,占用空间小。加工并制作了天线实物,实测结果表明天线具有良好的性能。更多还原

【Abstract】 In this paper,a monopole antenna is designed and the radome is also considered..The proposed antenna is fed by 50 Ohm coaxial connector.The antenna comprises of a monopole,a radome and a ground plane.The ground plane has a convex structure,which is good for improving upwarping of radiating pattern.The axial symmetry of its electric performance is guaranteed by the axial symmetry of its configuration.The antenna is fabricated and measured,the results show good performance.更多还原
