| 摘 要： | 利用阵列天线的不均匀性可以实现对辐射单元幅度和相位的控制以达到特殊波束赋形目的。传统设计中,基本没有考虑微带不连续性对微带传输线长度的影响。本文采用仿真方法获得了微带贴片单元的等效参数,综合考虑了微带不连续性对贴片单元长度以及贴片间传输线长度的影响,设计了双层X波段32元串馈矩形微带贴片阵列天线,实现了余割平方赋形波束。运用电磁仿真软件CST对该阵列天线进行仿真,制作了天线实物并进行了实验,结果与预期指标吻合较好。

| Abstract: | The amplitudes and phases of radiating elements of nonuniform array antenna could be controlled in order to
achieve special shaped beam. There was little discussion about the influence of the nonuniformity to the length of microstrip
line in the conventional design. In the paper,a simulation method to obtain the equivalent parameters of microstrip patch is
presented. Comprehensively considering with nonuniformity's effect,a 32 series fed microstrip antenna array at X band giving
the synthesis of a cosecant square pattern is designed. And by use of the software CST,the antenna array is simulated and
measured. The results agreed with the requirements. |
