| 摘 要： | 为了抑制波导窄边缝隙阵列天线交叉极化电平,采用一种在波导外壁开非倾斜缝隙、在波导内壁开倾斜缝隙的方法。利用电磁仿真软件HFSS进行仿真,得到孤立缝隙与阵中单个缝隙的电导函数。设计了一个47单元X波段波导窄边缝隙均匀直线阵列,与常规缝隙阵列相比,天线交叉极化电平降低了6.8 dB。

| Abstract: | In order to suppress the cross polarization level of the waveguide narrow-wall slot arrays, the waveguide with untihed slots on the outside wall and tilted slots on the inside wall is adopted. HFSS is used to do the simulation to get the conductance function of the isolated slot and the single slot in arrays. A 47-element X-band waveguide narrow-wall uniformly linear slot array is designed. The cross polarization level is suppressed by 6.8 dB compared with the conventional slot arrays. |
