Abstract应用矩量法对波长为0.70m的P波段抛物柱面天线进行了分析和计算,该天线的馈源由7元半波振子阵列构成.分析了馈源阵列偏离抛物柱面焦线时对天线增益、输入阻抗等性能的影响.计算表明,馈源阵列沿径向向内偏离焦线时,主要对天线的前后比产生影响,沿径向向外偏离焦线时,对天线的主瓣和前后比都产生影响.此时,天线输入阻抗的变化比方向图的变化明显.同样,馈源振子直径的变化对方向图的影响较小,而对输入阻抗的影响则较大.还对天线的波束扫描进行了模拟.
Other AbstractA numerical simu lat ion is conducted to analyze a parabo lic cylinderical ref lecto r an tenna w ith 72 half2w ave2dipo le array as feeder u sing the method of momen t s (MoM ). The inf luence of offset t ing the feeding array f rom the focal line is numerically studied. Resu lt s show that m inu s o r p lu s offet t ing of feeder along the radial direct ion induce differen t effect s bo th on the pat tern and on the input impedance. Resu lt s also show that differen t diameter of dipo les impactmuch mo re on the inpu t impedance than on the radiation pattern. Beam steering is also simu lated.
